I want to replace the stock amp and speakers in my GS400 w/ nav. Could I simply pull the amp out and replace it with the aftermarket one. In that case would I need a 4 or 2 channel amp? Second could I just pull and replace the speakers up front and those in the back, excluding the sub. If so what size speakers would I need to purchase and how deep of a speaker can I get. Any issues I should be aware of before attempting this?
(I couldnt find the answers to some of these questions using "search".)

Thanks,

Jackco

is a long process but u can do it ,just remember that u have to do and extra speaker for your navi or else one of the guys here did a thread abut burning the ecu unit for the navi sys. so just becareful when u do this are you going to the meet this weekend on Long Island I'be there and let you check out what I did but if u don't I will be happy to help u. u have to strip the doors panels apart , the rear seats ect... it took me about a month to do this but you have to understand between work , family and my house.but i did it .

That looks like a good job.....but what is that? It doesnt look familiar.

this is what I am planning when I get some free time, since the amp and the nav computer will be in the trunk (all the audio signals are in the trunk for all speakers already from your amp installation), it should be easy to get an audio sense unit ($10), when it senses that NAV computer audio output, it will trigger a relay($2) to switch the driver door speaker wires to the NAV signal.
This is simple and quick. I just don't know how fast the sense unit can activate the relay yet, but it's simple enough to try, instead of adding new speaker.

I think it just easer to add the extra speakear the wires that come the navi to the front left speaker are undernet the rear seat is simple you cut put the one line from your front left to go to the back aftermarket amp and the other line to the new speaker I will try to put all the pic later i just don 't know how on my profile we can do this right guys?

angelslex,
from your picture, I can't figure out where you mount the extra speaker? in the glove box?

angelslex

is on the drivers side under dash by the parking cable release you will no problem listening to the voice fron the navi. Bananas have you ever or someone you know use that unit they call pb-1and the pionner tv tuner or something like that to play dvds on the factory screen?

BananaGS

Yeah Im pretty curious about that device also ( to play DVDs on nav screen).

ANGEL what size speakers did you install? One shop says 6.5" another says 5.5" inches and this site says 4". I have no idea who is right.

Also I would greatly appreciate some advice from all of you out there, II dont know what to go for,

I have one shop quoting me $1k for MB Quart componants front and Coax. in back with a PPI amp.
Another $1k for kicker k6 componants up front, pioneer coax. in rear and pioneer amp.
Another $900 for an all pioneer system.

I am at a loss of what to do. I am thinking of just going with the MB Quart...whcih Ive had before and enjoyed.

Thanks all,

Jackco

you can put as much as 6.5 if you want to but I went with 4" my self i just need it some better than the stock speaker Im an Alpine guy my self and seen Im in the business I got them for like $45 a pair .But check out bananas site he went all out. I can't really do that anymore man I got 2 kids and man they always telling me daddy lower the bass.

angelslex

you guys think that a 12" solobaric L7 dual voice coil with vented box new for $310 no tax is good ?
