So I am thinking about finally upgrading the factory speaker amp. I already have an aftermarket sub with amp using a line out converter straight from the the original sub location. My question is, will I have to move my LOC to where the stock amp is once I splice into it to run the aftermarket amp??

 

Not necessarily. Pick up an amp that is known to accept our low voltage, balanced-diff signal and play without a problem. JL hd and xd come to mind. XD's are cheap right now. What's your budget?

 

I took the post amp signal and it works just fine. If you have a loc already and your amp has pre-outs you could try it out to see if you like it. The processing in the stock amp does make the speakers last but also makes them sound good.

 

About $400.
All I'm worried about is cutting the signal to the sub once I take out the stock amp.

 

Leave the stock amp in for rear fill and center channel.

 

No need to remove the stock amp. Most of us still have it for a few things (HFL, Center Channel, Rears, etc).

 

Wow I hadn't thought of that...

so just rewire the front then I'm guessing? BRILLIANT!!

 

Leave your sub LOC in tact - don't change it.

Tap into the front speaker wires near the stock amp - pre-amp if you want better sound quality (might need a line driver, signal converter, or an amp capable of doing both), post-amp if you want less trouble.

You will need two different sources unless you want a lot of work. The current signal and LOC will not play above 80 hertz, or so, and is not capable of driving components.

I would buy used JL slash amps before you get XDs... might be just me, though, with too many bad thoughts of TMA and e series JL products in my head. Go all the way, or go home with JL - their cheap stuff is still cheap IMO.
