NEED Help with LOC in 07 Tahoe. All help is welcomed.

[Pyrofan]

So, tapped into the stock sub wires per 2007+ Tahoe Add-an-Amp - Chevrolet Forum - Chevy Enthusiasts Forums and put my LOC in and was testing the RCA cables. I had the DMM on AC voltage and got zero. So I thought my wires were not hooked up to + and - so hooked my LOC + and - connections straight to the battery. Still read 0 on the DMM. What do yall think? LOC bad?

I'm assuming that you had the radio turned up to listening levels? What loc are you using?

How high does it need to be turned up? Its a LOC2SL. Is from Wally World.

Depends on how sensitive your dmm is. Also, have you adjusted the gain on your loc? My limited experience with loc's is that they do not put out a strong signal. Is your factory sub still hooked up? Or are you just running the speaker wires into the loc? I can not find anything about that particular loc as far as specs go.

When you are testing the RCA; are you only testing one at a time with the postive lead touching the middle pin, and the negative touching the outside circle shield of the RCA?

Its hooked to the "sub wires". They are apparently not full range but just for subs. Ill try maxing the gains and higher volume.

Yes I know that. Thanks for the input though!

Try hooking the factory sub back up and see if it works, then try connecting the loc while the sub is still connected. if the sub plays but you still don't get output from the loc just get another cheap one, I think I spent like 10 bucks on mine.

And don't max out gains on the LOC, I did that for a while and whenever I turned off my radio my subs would play a constant loud bass note until I turned it back on. (I guess whatever interference was picked up in the speaker wires)

Well LOC didn't work. Got the PAC unto to work though. All is good
