2 Alpine 12" Type-S
q-logic box
MTX 4002 400 Watt 2 Channel Amp
Hi-Lo Converter (Because of Navigation System)
Speaker Wire
RCA Cables
Amp Power Kit

Installed at Circuit City for $55

They didn't have to go into the dash, they hooked the hi-lo converter to the stock amp (passenger kick panel)


Subs ^^^


Amp is under the passenger seat ^^^


The knob is the remote bass adjust (came with the amp)


A closer pic of the bass adjust ^^^

The sound and everything is great. The only problem is a trunk/license plate rattle, but that is common for most trunks. The q-logic box is also kinda small for the subs, so if I turn it up close to the max, there is a weird sound from the subs, although you can't hear it unless you open the trunk and go back and listen to them. Im going to get a bigger box or ported box soon though, and it should fix the problem

 

Cool - but take better pics :-D Too blurry!

 

k ill put some more pics up later

 

does it sound good with the exsisting stock speakers??? Can you control the sub's and base from the stock head unit? what kind of music do you listen 2???

 

how much was everything?

 

It Sounds Good With Existing Speakers:

I listen to Alternative Rock to Country to Rap/HipHop

The subs sound excellent with HipHop/Rap at almost any setting
Alternative Rock I just turn the bass knob down a little and it sounds great too
I havent put in a country cd yet but if I dont need too much bass ill just turn it down

The Bass Knob:
It does the exact same thing as the subwoofer control from the Headunit.
At the Moment, the Subwoofer Level in the headunit is set at -3 and the knob is set at 50% for rap
For Alternative rock i turn the knob down to 25%. Its easier to turn the knob than to push the thing on the nav screen, so i just use the knob.

Costs:
Alpine Subs $100 Each. Get online
Q-Logic Box. $100. I dont reccomend the one i got, its too small. Read the Subwoofer specs for the best box type. Get a custom one of you can. They cost about $100-$150
MTX Amp: $220. I got it at Circuit City
Hi-Lo Converter. I got mine at bestbuy, circuit city has them too. $15-$25
Speaker Wire. $10 at circuit city
Amp Power Kit $80
RCA Cables $30
Install. $55 at Circuit City in Frisco, TX

Install was a pain in the ass. I went to 2 bestbuys and 3 circuit cities and a Tweeter. Everyone wanted to charge 120 to "fiddle with the nav system." I was like, im paying you $50 because you have no idea what youre doing? Finally I found a CC where I told them i dont want to take out the nav system, just tap into where the stock amplifier is. They installed the amp, subs, and bass knob in about 3 hours for $55, i tipped the guy $10.

Total about $700

 

MORE PICS:

 

I would just like to add you do not need 2 12" alpine subs in a TL. I went for the excess. When the Volume is at 4 you can feel the subs. Anything higher than 18 with the windows up and I will be loosening screws all over the car

My Subs are rated at 300 Watts RMS 900 Watt Peak EACH

Im only running either 100 watts RMS or 200 Watts RMS to each sub. Im not really sure. The point is, I am underpowering my subs by alot, and i dont even increase the Sub adjustment in the headunit. That means that, if i had 300 RMS to each sub, or raised the subwoofer boost, It would sound even louder

 

sounds good. What exactly does the high low converter do? I have the same exacut car as you with nav

 

With most aftermarket headunits, there are RCA jacks in the back of the headunit that connect to the amp. Stock headunits usually don't have this RCA jack, so what happens is the Hi Lo converter converts the wires going to the rear speakers or sub and turns it into RCA. It just a small converter. Of course there is a tiny bit of distortion due to this, but you probably wont even notice the difference because it is so small.

 

for $100 each u shoulda got the alpine Type-r 12's

 

Looks good there!!! I have the similiar set up like yours except I am running RF 1001bd (1000watts) into a pair of 12 DVC Alpine Type R subs. THey are so loud that my trunk rattles like crazy. I don't know if you have the same problem where the trunk flexes in and out. Yes you can see the sheet metal vibrating like crazy. Thinking of dynomat but I don't think it will solve it 100% tho. You should check to see your box inside if it have a divider so each sub is in there seperate chamber. If not, then maybe that is what is causing the noise when you open up the trunk. A seperate chamber is the way to go and would sound alot better in terms of base and distortion level. Just thought I share that with you.

 

yeah i have a seperate chamber for each sub. The box does look kinda small. It seems to be made for like Low-end subs that Circuit city sells. The Alpines might be too powerful for it.
Also, My trunk does rattle like crazy if i turn the subs up alittle more than normal. Dynomat is definately required. I have not turned the subs past 50% of their full potential, so i cant even imagine what happens if i turn everything up to it's max.

 

I have a question though, whats the best way to put dynamat in and around the trunk?

 

You do not need the hi-low converter. For my car, I just tapped the sub lines before factory amp and attached a pair of RCA's to it. The sigal coming from the head unit it "low level" and "amp friendly". I guess the only good a hi low converter would do is allow you to adjust the gain.

 

update: Each Alpine Sub blew a voice coil for some odd reason... anyways, the i returned the subs for a refund. Now i have 2 Infinity Reference 1230s. I used the extra money from the alpines to upgrade the amp from a 200 watt per channel 2ch amp to a 600 watt mono amp. The MXA6001. The infinity's require a breakin period, so i will tell you how well this goes... Ill update pics tmr.

im pretty sure i blew the subs because i didnt let them breakin. I turned up the volume first thing... and my previous amp was underpowering them, causing a clipped signal. Underpowered subs + No Breakin + Turn up Volume = Blown Voice Coil.

 

Infinity Reference 12" 300 Watt RMS 1200 Watt Peak Subs:




MTX MXA6001 Mono Amp. 600 Watts RMS @ 2ohm:



The Reference Subs are very nice even though they are infinity's entry level subs.
$185 For the pair at Circuit City.
At first they sounded good. After about 5 hours of breakin they have gotten alot louder (The CC guy told me to break them in for about 10-20 hours)
I would definately recommend them if you have atleast a 500watt amp to power them.

 

Nice setup son. I have a single Infinity 1230W in my SSM TL right now. The bass is good, nice and clear. I've also set my amp to pump the bass at 40Hz which is nice deep and airy bass that you can feel. I've been debating whether to get a second one but sometimes it gets so loud and am sick and tired of hearing my sunvisor rattle when I set the volume to 10 or more. So am not sure how 2 of them will sound. I also don wanna have a gansta looking TL with tinted windows and a rattling trunk. Might leave it as it is. How do yours sound? Will you need to dynamat the trunk?

 

Yeah i will definately need to dynamat the trunk. With the trunk closed and volume past 8 it starts to rattle. At Level 24 from the outside it sounds like crap, but inside you are enveloped by bass and it sounds sweet. I don't even need to call my friends when i get to their houses anymore, i just turn the volume to about 24 and pop open the trunk. They usually hear the subs and come outside within a minute. My sunvisor doesnt rattle, but the rear deck rattles alittle too. You can't hear the rear deck rattle unless your in the back seat though because the subs are loud enough.


Hey what is your amp setup to...

I have a 600watt mono, and the crossover is set to 150hz, but i can turn it down to 40hz if i want... SHould i do that?

Also my gain is at 100% but the navi headunit subwoofer channel is set to -4

The Bass Boost on my amp is set to 50%

I also have a remote gain adjuster and it is usually set to 10%-50%.

 

You should turn the gain on the amp down a little (to 50%)and turn up the subwoofer channel on the head unit (to zero)... this will feed the amp a little more signal... it wil be happier not running at full gain and it will sound the same volume w/o running the amp with no headroom... it's like driving your car at top speed all the time.... you'll make the engine very unhappy...

feeding the amp more signal is the same principle as having an aftermarket head unit that puts out a higher voltage at the pre-amp.... the signal stays cleaner and it sounds better because the amp is getting a stronger signal

 

yeah i would have done that except the mtx amp i got came with a remote bass adjuster. It is the black knob thing next to my VSA OFF button. What it does is adjusts the gain. So when my amp is set to 100% gain, and the remote adjuster is at halfway, the amp is only at 50% gain... if i turned the knob up all the way it would be 100% or where i set the actual gain to. The MTX amp is very nice. Very clean signal and great power.

i was able to fix the rattling using peel n seal: https://acurazine.com/forums/acurazine-clubs-meets-15/so-cali-valley-meet-112427/

 

make sure you put grills on front of those kappa, great subs but easily breakable.

 

150hz?? Turbowhat2- bass frequencies are between 25-80hz. tune your amp to a lower cutoff frequency and it will play lower bass notes. With it set at 150hz, your feeding your sub treble and mids-NO GOOD! Pick a good sounding frequency, it might sound quieter, but the bass is lower and the sound of it will actually travel more.

 

Oh by the way, I have the epitome of overkill with my system. I also used hi-lo converter. I have an MA audio hk-602sx amp that plays 1500watt (rms) to two channels, 6000 watt max. I have a poweramper 6 farad 'powerbank' power-cap, and two audiobahn AW1208T's. They are 1500w(rms) and 3000w max-each! I used to be all into spl, but now in my nice new tl I think it makes me look kinda immature. At volume level 1 i can here it inside of my house with the car outside. At any volume level over 10 will rattle the cups and plates inside my kitchen and have my woman come out screaming. Definitely need more mids and highs, sounds out of balance. Overkill.

 

i had those type-s..they blew out, 3 times, so now i got a new kicker cvr rated at 800W rms with a 800W audiobahn sub

one more thing, does anyone feel like their music is more distorted because of the hi-low converter?

 

I have a Rockford Fosgate Hi-low converter and it works great. I can adjust the gain on it and paid only $45bucks for it. No distortion here!!! Very clean and the base notes hits very hard and tight!!

What kind of converter do you have?

 

Hey buddy....your X-over is set way too high dude. Mine is set at 50hz and it is perfect. Unless you like more punchy base then you should set yours at no more than 75hz. Would you say your new subs play louder than the Alpine Type S subs?? You should of gotten the new 2005 Type R subs. I heard they pound even harder and louder. Just my

 

yeah i turned the crossover down to 90. The infinities sound great. I have some bestbuy hi-lo converter and maybe i cant tell what is distortion, but it doesnt seem like i am getting distortion (or i just cant tell).

I have a question. When i put the subs all the way back, it doesnt sound very good if im back tere with the trunk open listening. I think it may be the stock sub resonating???

because as soon as i pull the subs toward the middle or near the trunk opening the subs sound a lot better. Its only when i have the subs way back near the back seats does it sound kinda crappy. From inside of the car there is no difference in sound... everything sounds great its only when i go back and open the trunk and listen.

 

Hey Turbowhat2,

Listen i really want to make my system a bit more loud. Now i dont want 2 12's and all. Basically this is my hopefully simple plan. And i would like yours, and THE REST OF YOU WITH AMPS advidce. This is what i want. I use to own an alpine V12 5 channels amp with a bazzooka. It was great. I loved that amp. lasted me 3 years and then i sold it. Cuz i was "i think going deaf" lol.... because i kept it for hights and baught me a 1800 watt hollywood excursion with 4 12's kickers solo's... but anywhooo.. this is what i want. i got a 3rd gen TL. and this is the amp i want to get. below is the link.

http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW

Basically i want to do this just to add a small 10" sub in the rear. Thats all. But at same time i would like all my interior speakers to sound louder. Becuase i dont want bass to over power the highs. And besides the point that i take my radio volume to 35 now. i would like to just be able to get it to 15 and sound nice and crisp.. What would i need. This is my first car that has this 5.1 dolby sound. all other cars have been plain and simple 4 speakers.. And i know that tweeters can be hooked up with door speakers liek chain. done that before and works great. But my only concern will be center speaker.. What do you gyuys think about this? Need to ask me anything to conclude your opinions? thanks in advance.

 

i had 2 kicker 10in L7's in the back for a few months but the sound from the outside of the car was horrible... i tried everything to stop different things in the trunk from vibrating but the entire trunk lid would make high pitched sounds every time the subs were on. From the inside the rear deck rattled too much so i decided to remove the subs. Im sure you all expereince these sounds 2?

 

with my set up, i still have the center speaker. it's still being powered by the stock amp. all the other speakers i changed and bought 2 more amps, one for the sub and one for the inside speakers. i still have my surround sound, only thing is, i have to turn the center speakers all the way up on the console and when the navi voice talks, it's a lot lower that the rest of the speakers. i could hardly hear the voice when my volume is set to 8.

 

WEll you see. i think that you have an amp for the sub and and a 4 channel amp for your speakers inside right? if so its the same that i am going to do. But just a single 5 channel amp. 4 channels highs and 1 channel sub. sorry to ask. But the voice you cant hear is the NAV voice? or what? did u see the link for the amp i want? i love them!!!! have had awsome experience with ALPINE v12's!!!!!! nothign else for me when it comes to highs!!!

 

\\????

 

check out my sig, it has the model numbers of the alpine products i use

you are correct, 4 channel amp for the inside speakers, 1 mono 400 watt amp for the sub and the stock amp for the center speaker. yes the NAV voice is the one that comes in low coz it's still uses the stock amp. all the stock options are still there. when the NAV voice comes on, the speakers lower. BT phone now comes in a lot louder. though i don't remember whether or not all the speakers were used when i had the stock. with the new setup, all the speakers put out my phone conversation lol

as far as the DVD-A, it comes in great even though the center speaker uses the stock amp. i have the Linkin Park Reanimation CD and DVD-A and i can definitely tell the difference.

 

Sparkz, Do you have wiring color codes or a pin out for the pre-amp signals? I too would like to tap into pre-amp input on the amp as opposed to using a hi/low impedance adapter. My TL is in desperate need of subs. That 8" thing on the rear deck is a sorry attempt at bass... TIA

 

Wiring color codes would be great. I am picking up my new 05 TL this weekend and will need to take my two JL-Audio 12s out of my 3.2CL to put in the new ride.. Anyone have details re: the following?

1. How did you run the power cable from the battery to the aftermarket amp (I would assume which is in the trunk)?

2. When you guys say you are tapping into the pre-amp signal, this would be the wires going into the amp from the HU, right? Where exactly are these located, and does anyone have the color codes for what two wires will be + and - for the sub-woofer channel?

3. What are you guys hooking the remote wire up to for the amp?

4. Is anyone leaving the stock sub hooked up as well?

I'm sure I'll have some more questions, but want to have all my ducks in a row before I go messing with the new ride. Definitely don't wanna mess anything up, and I don't trust a shop like CC or BB to do it properly, so I am going to tackle it myself, I think. Thanks for all the info and guidance!

 

If you guys were smart you would get a 5ch amp and and a separate mono amp.. this way you can amp the center channel speaker.. would help a bit.

 

i building my custom trunk right now with my friend..ill post pics after we're done...its been 4 days and we are only about 80% done

 

port the eclosure thru the pass thru and you won't be dissappointed... NO RATTLES...

Just so you guys know..


I love my install.

ryan

 

which direction are your subs firing? (do they face the trunk, face up, or face towards the cabin?)
