i want to install some subs and amps. i wanna go all out jl. 1000 watt amp and 2 jl 12"s. now my question is since i am keeping the stock headunit. how do i go about hooking up the amp to the factory stereo? i know how to do it with an aftermarket stereo. but not with the factory stereo.

their probably is posts answering this or this is a recurring question but i would appreciate it if i could get a straight for answer or a link to another post. thanks. no flaming plz.

 

Get a LOC, cut the wires to your stock sub, and tap into those wires, that way you have FULL control of your sub via the stock head unit.

I also recommend removing the stock sub

 

what is a loc and where can i get one ?

also, the method of cutting into the wires to the head unit. is that called an amp bypass ?

 

an loc is a low level output convertor. it takes your stock sub wires and converts it into the rca outs that it needs for the subs. you can get it at car toys for a bout 20 bucks if you dont wanna spend a lot. they range from 20-about 150ish for a high quality one. i have a solo baric and a 900 watt monoblock soundstream amp. the 20 dollar loc is doing its job

 

I think you'll want to hook up ALL the stock HU speaker wires to the LOC, run the RCA outs to your amps, and then speaker wire from the amps to the speaker locations. Otherwise, your interior speakers will be getting run just from the HU and you'll have TONs of base from your amps/subs. Won't sound right. The LOCs with multiple outs (front, rear, sub, etc.) cost a little more - the one I'm looking at is about $160.

 

Does anyone know which wires are the sub and center channel? Doing my amp bypass with LOC but I don't know the +/- for the sub and center channel.
