Im thinking to get the JBl Ms-8 for my 04 TL

Just had a question about the install
If i take the Pre amp (gray connector) to the MS-8 input do i need something to boost the signal

also

if i do this will i loose my Nav voice or HFL

 

Dude, you can ask more than 1 question in a single thread and people will answer.

If you omit the center channel completely, you will lose you your voice. If you include the center channel signal, you should be fine. A line driver shouldn't be needed.

 

my bad man just kept posing as questions arised

so if i wire the pre amp signal to the Ms-8 then i plan to use two amps a small one for the center and one bigger one for sub + 4 speakers i will be good

i dont need a line driver for any of the signal

 

Pre-factory amp to the MS8 requires a line driver. If you use the setup CD it will say "signal low" even with the head unit turned all the way up.

 

have any recommendations for line drivers?

Or is there any way to do the tl with either a just line driver or just a processor

 

Rf bld

 

But im looking to keep my center and sub channel thats only a two channel driver right?

 

I think you have been advised already to keep your center channel and rear speakers on the OEM amp. use a line driver and feed your processor and amp they will take care of separating the sub off. bridge your 4 channels to the front components sub channel to sub. your done easy easy. check my thread " Mild grade fever"
for the same setup except no processor.

 

ok got it thanks
so this can be done without the processor?

 

If you go with an MS8 all you need is a left and a right full range signal and the front left and right gives you that. If you do run an MS8, you can't run other speakers off the stock amp or anything not through the MS8. It has a built in time delay on all speakers making this impossible. The MS8 does some very neat things with a center channel and rears in Logic 7, one of the coolest things I've heard in a while but you have to let the MS8 control the center.

I've posted how to retain your center and HFL through the MS8. The center channel has to be used as the 3rd input during the setup disk. Once it "sees" the center it uses it as an input. When the navi prompts pop up, the navi plays over the entire system, not just the center anymore. When you use the HFL, the voice is over the entire system, not just the fronts anymore. I have some threads on the MS8 if you want to read them.

 

could you post up those threads for me

 

I will say I hate how you have to "mute" the MS-8 to use BT without having the other person on the line having an horrible echo.


OP -- You'll take the FL and FR (pre-amp) wires and wire them into the RF BLD. Take some long RCA's and run them from the BLD (try to put this as close to the source as possible. I fit mine up by the stock amp. It's VERY tight lol). RCA's from BLD to MS-8 input. Then run RCA's from your output channels to your amps. When you go through the MS-8 setup it will have you dial in the voltage so you can raise/lower the gain on the RF BLD until it tells you you're in the prefect range for the MS-8 to use. Then it's cake from there on out. You're done.

Don't forget to run the wire for the MS-8 display while you have everything out and being wired. Trust me lol. It's annoying to break it all down again just to run the damn display cord.

 

so thats the only input i need (FR and FL to BLD to MS8) then i can use all the outputs on the MS8
i was cofused thought that you had to have 8 inputs to use 8 outputs

 

nope, only FL and FR and it will distribute the full range signal over all 8 channels. You'll make your crossover settings while setting it up

 

ok got that lol thanks

what about keeping the center and rear speakers on the factory amp and changing the fronts and sub what are my options there Do i need a processor, or how can this be done

 

JBL - belongs in the round can under the desk.

 

Your gonna need the center channel also if you want your voice prompts or just keep the center on oem

 

Hmm, I've had my MS8 for over a year now. When I run the setup, I get an OK signal around 34 volume on the head unit. I'm using the preamp, do I still need a BLD?

 

1. I'm wondering if you're using the post-amp

2. That means you don't see a 2v signal (or possibly not even a 2v signal) until volume 34 on the head unit. I've always heard the ms-8 can get weird with too low or too high of signals coming in

 

I've thought of that at times but I'm positive I'm using the Pre-Amp signal. I'll double check some time.

 

Well as long as it works for ya. I know IHC said it wouldn't work and with my BLD turned all the way down I get a "low signal" or whatever it is on the MS-8 setup. I like to have it not go past 20ish unless I'm really looking to crank it.

I'm not sure of the issues that would arise with having to take your volume to 34+ to get a decent signal. I can't remember if someone proved or disproved that the factory HU has some EQ built in when you get into the higher volumes

 

The above is why everything has to be run through the MS8, nothing can be run off the stock amp that's not run through the MS8. The center should be run off of the MS8 since it's one of the benefits of running an MS8.

 

Im all confizzled

 

If you have a MS8 you have to run every speaker through it. If you try to run the center or rears or sub from the stock amp or aftermarket amp without going through the MS8 you will have an echo.

Use only the front left and right inputs to the MS8. From there the MS8 will split the signal for the appropriate output channel. It does neat things when you use the center and rear speakers. Using at least the center channel will give a good center image in both seats.

If you want navi voice, use the factory center channel input into the MS8 in addition to the left and right signals. When the navi prompts come up the music will be muted as normal but the navi voice will come over every speaker instead of only the center.

 

where does the BLD come into play

 

It boosts the pre amp signal! Thats why you started this whole thread???

 

So, will I only need one RF BLD to run two amps (no processor )?

ID Q450.4 for components and JL XD600/1 for sub.

 

Yes if you're running into a processor because they split that FULL RANGE (20-20kHz) signal from our FRONT LEFT and FRONT RIGHT PRE-AMP signal into however many channels you're going to use (aka however many the processor has) You can use all 6 channels, 8 channels, 4 channels...whatever! on the processor by using our FRONT LEFT and FRONT RIGHT PRE-AMP signal as the INPUT

05NBP- Without DSP, i dunno lol. I'm not sure if you'd be able to daisy chain the amps (if possible on the amp(s)). Never done it that way so I couldn't be any help here. Hopefully someone will chime in for ya
