    People with NO HeadUnit, Recommended AMP!!

    This is what i plan on doing, no HU, carputer goes right to AMP - My stock AMP has no RCA plugs and found out my stock AMP wont work without the stock HU,

    So basically I have to ditch the stock AMP and HU
    I now nothing about how all this audio/AMPs get hooked up
    In gonna get it professional installed,but i dont know what to look for on the AMP,
    i think my car is a 4.1(2 fronts,2rears,sub) so the AMP i get, should have 5 RCA "inputs"??

    what AMPs are you guys using without the HU??
    Dont want to spend more then $100 - 150(if possible)

    Now let me get this straight - once my AMP is hooked up with the current stock speakers i just plug my lineout on PC to the rca inputs on the AMP, & I should have sound???

    I just want to get an idea before I go to the install shops, alot of then here(NYC) BS ya alot

    thanks

    your going to have trouble finding an amp at that price.

    you dont NEED a 5 channel amp (they cost more) you can live with a 4 channel amp... but it has to be a good one, or 2 2 channel amps..

    if you use a 2 channel amp for the 4 speakers inside, and a 2 channel amp (bridged to 1 channel) this will give you the most cost effective solution.

    or if your really trying to keep it under 100-150.. you may want to keep your head unit and stock amp.. and use a rf modulator or a aux or cd input converter for your stock head unit.

    If all four speakers (all 4 corners) are 4 ohm, you can get away with a 2 channel amp as long as it' 2 ohm stable.

    (front) have 2 ohm impedance values. Rears are 4 ohm and the sub is a 2 ohm

    Can a 2 channel AMP be good with this?

    Na that would be no good, the whole purpose of this project is for me not to use a HU

    No that's not gonna fly. Are you sure the fronts are 2 and the rears are 4? What kinda car do you have?

    what makes you think you cant use your stock amp - as long as it has inputs behind the dash you can convert each RCA into a +/- speaker wire, and if you can grab a switched 12V you can turn your amp on without the HU...maybe an idea if you REALLY want to save time/moeny.

    what kinda car do you have? my audi's BOSE amp can work without a HU....just takes some tweaking....

    Face it... you're going to need to spend more than 150 bucks. You'd need at least a 4 channel amp and then a 2 channel in bridged mono. Not to mention that you'd need either a build in x-over for the sub or a seperate one. Since you're speakers are wierd impedances you're going to have a hard time finding 2 ohm stable amps for that cheap a price range also. Plus, using stock speakers with upgraded amps usually isn't a good idea since you could potentially fry your speakers. All in all... you're in over 150 bucks.

    Why do you want to go through the trouble of installing a versital sound system, that you apparently have in mind, only to short yourself in the department that actually makes the sound?

    i know cause many people who are VERY familiar with lexus audio systems and who actually tried different setups said it cant be done , Here is one response i got :

    "He said the car's AV stuff is very very integrated with the car, 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"

    see when i first came onto this site, i thought i could just use my stock speakers and AMP w/no HU, when it comes to car audio systems i know very very little
    i guess my best bet is to just take it into a professional install shop and make them do it. the PC part i have no prob. doing(setting up,running wire,making custom fabircation for indash LCD screen,etc..)
    just trying to get this audio figured out is a pain

    never said i wanted/had in mind a "versital sound system"
    Im no biggie on sound , my stock speakers and sub are fine to me
    The reason i didnt want to go over $150 is because i rather put the money into other things for the PC,GPS Software....like i said sound is not that important for me cause i think my stock speakers sound fine(if they didnt sound good then id be in a different situation)

    thanks guys for all your info/ideas
