    anyways... if you got an electrical service manual for the car, scan up the pages for the audio and I'll look at it for you, and test on his car... it's the easiest way to figure it out.

    As far as amps... there's alot of good amps out there... it really depends on what you want to spend/what kind of power you want.

    I've got a soundstream reference 405s for sale
    WoW thats some good free Mods have any pics of the GS what size rims?

    Im sure i can get that manual from lexus? that would be great if you can let me know whats what, Maybe your friend wants to do the same thing

    Now as far as AMPS is the one your selling gonna work with my car(replace my stock AMP)can i hook up a USB AugilyNX to it or use any kind of 4.1 sound card?

    Im really not into the sound that much, i think it sounds fine w/stock speakers and sub, how many watt AMP is that

    If the numbers are right ill take it off your hands

    Here is a PIC of my car(lots of Mods), If your friend has any questions let me know, there are sooo many Mods you can do to this car, look me up at CL (under same screen name here) See the Thread i started at CL about this

    I suggest you buy 2 amps, a 2ch (bridged for sub), and a 4channel (all your other speakers), or one 5 channel amp (like mine, but I have a 2 channel as well). Crossover points can all be set internally via the SB audigy 2 NX software, and it's really quite good. I had active crossovers on the amps and just used those in the end.
    yea I think ill go with just one 5 channel AMP
    One of the electronic guys over at club lexus said
    "Be careful in that the stock speakers (front) have 2 ohm impedance values. Rears are 4 ohm and the sub is a 2 ohm"
    Can this be done? not even sure what that means

    Now when u say Line-Inputs this means if i keep my stock AMP, correct?

    If i cant do it this way, i wont bother doing it at all(too good to be true)....i think this is a great idea, better then having the stock NAV option, ALOT cheaper too
    How would i power the touchscreen?

    I did a seperate volume knob, just desoldered the unit off the audigy nx board, and extended it to the LCD trim panel. Seems to work really well, even has a nice overlay volume bar when you change the vol.
    Thats good to know,maybe you can ask him a question for me can i use a factory AMP without the STOCK HU
    see what he says would be the best way on doing this

    That seperate volume knob is a great idea, but you can also control the volume through the touchscreen(windows) , right?


    thanks again guys for all the help

    Yes, I'm not sure if your stock amp as line level inputs. a 5 channel amp like mine, the APX500.1 Clarion is pretty affordable anyway. Remember one thing though, the sub channel, cannot run in fullpass mode, only low pass (meaning, it can only really be used for a sub, no center or surround speakers).

    How would i power the touchscreen?

    You can do it, there are lots of helpful, knowledgeable people on this board, the questions you are asking are the right ones, even though they show you are inexperienced with this stuff. Do some searches for ohms, and speaker basics, move on to the groundloop page at http://www.epanorama.net/documents/g...oop/index.html , and find a friend that knows how to configure weird drivers in windows XP . The touchscreen I used, and lots of other people use, is the lilliput XGA touchscreen, sometimes there is an ad about it along the top/right of this boards pages (lilliput now). It comes with a 12v cigarette adapter, just cut the cig part off, and wire it to a switched 12v source from your car somewhere.



    Thats good to know,maybe you can ask him a question for me can i use a factory AMP without the STOCK HU
    see what he says would be the best way on doing this

    He said the car's AV stuff is very very integrated with the car, setup for AVCLAN even if you don't have GPS/Nav. He hinted that the amp might be controlled by a "bus" of some sort, and turn on digitally, instead of a simple 12v switched turn-on. i'd say ditch it. The factory speaker wiring should all be at that amp location, and those should be fine to tap into with your 5 channel amp.


    That seperate volume knob is a great idea, but you can also control the volume through the touchscreen(windows) , right?

    Right. I haven't had to use the touchscreen part yet, except one time when the music was louder than the GPS voice prompts.

    the amp is a soundstream reference 405s
    it's 1/2 ohm stable..
    here's the values at 4ohms 12v (it will give more power at 14v)
    25x4
    100x1
    it has builtin crossovers.

    I had this running my full system in my old car and it sounded great
    4 - 5 1/4 mb quart
    4 - 10" rockford subs @ 1ohm

    rock solid... slightly low on power, but has never failed on me.

    my roomate wants to pretty much get rid of his deck too.

    as far as his rims, they're just the stock 17's

    see im really not to sure what all the numbers mean
    will this AMP work in my car?

    what im prob. gonna do is build the pc,indash frame for my 7" then get it installed by a installer

    or do you think i should just get the amp installed by an installer so everthing is working w/stock speakers and HU
    Then I can remove the HU and plug my soundcard into the amp........would it be that easy

    does your roomate wanna do a carPC ?
