Has anyone experianced this problem? The higher the volume on the radio the lower the bass goes? I just installed Alpine Type-R subs along with the Alpine 1000watt amp. And when I go over 20 on the volume the bass drops out. Anyone know whats going on?

 

Actually I believe it cuts Treble and Bass to neutral levels starting at the volume of 30.

Its very absurd having extra bass at 15 and none at 35

i need a system

 

you slut

 

you whore!

 

lol:P

 

is that treble/bass neutralizer crap part of the headunit or the factory amp? anybody know?

 

any pics of the install?

 

I will post pics as soon as its all complete.

 

So no i am going to have to throw a new deck in =X

 

are you running the subs off of the stock amp signals?

 

I have no lack of bass at high volume settings...

 

Im running the subs off of the Alpine m1000 amp (1000 watts)

What do you mean by the stock amp signals (Im not audo knowledgable, so...)

 

i mean is the signal for your subs coming off of the rear speakers. i have no drop in bass and either does slo007 and both of us eliminated the stock amp.

 

So the radio has no control over the bass limiting, the audio guy is telling me that I cannot bypass the stock amp.

 

Where is the stock amp located? Maybe I can find out what's going on myself.

 

Jigga and Slo.. Are you guys using the leads to the rear door speakers as the input to your amp? Where are you getting the input to the amp from.
Just picked up some alpine S for the (4) 6.5's and (2) 6x9's. Circuit City has a sale right now, buy a pair get the 2nd half price. Now I'm thinking of amping the 6x9's and one pair of 6.5's

 

For "raw" low level signal, you can...

 

so what's going on now is that I have to buy a bew deck with 3 preouts one for fronts one for rears and one for subs, and this is the only way to get the best use of my stuff right?

 

Of course you can. It's located behind the "not an ash tray". Pull the large center bin with caution not to scratch nearby surfaces (no screws involved) and you'll see the wiring going to the OEM amp just below.

An electrical drawing for the wiring is located somewhere in this forum. Run a search for it.

The crossover for the bass is located in the OEM amp. Bypass the amp and you'll have no problems.

EDIT: The OEM amp takes off all the engine noise from the audio signal that comes from the OEM head unit. You'll need a very good LOC or line driver to get rid of the noise. Several threads have brand/model suggestions. Tuan209 has some good suggestions.

 

That will make the best audio, but it's not necessary.

No, I pulled the audio signal for my set of front speakers and sub from the HU.

The rear speakers (still stock) run from the OEM amp.

 

I'm in a good mood:

 

Found another pic:

 

Alpine S are good because they fit easily. No cutting required. Good choice!

I used the low-level signal from the HU: lot's of engine noise there, but no ups and downs in frequency present elsewhere. For woofers (6.5), you'll have to bypass the stock amp to amplify it. Otherwise, you'll get distortion since the signal is already amped. A good LOC or line driver will cut the noise away. ** Emphasis on good, not the $20 stuff. **

See the drawing I posted above for the wires you'll need. Make sure the audio wires are in the opposite side of the car as the power leads to the amp you install.

 

So you think if i bypass the amp i should have no problems with this bass?

 

wow that's the first time i've seen the stock amp. isn't it cute. haha.

 

Correct.

 

thanx for all the help guys!
