I know I should use a line converter. I'm wonder who has actually done this? how does it sound? thanks.

under normal use, you wont notice much difference, obviously you're not going to enter any SQ competitions so it should be fine for daily use.

I have a MTX Thunder 8000 12" with a Rockford Power 300 pushing it. I am running the amp in 2 channel mode and have them each pushing one coil since my sub is dual voice coil. I had it like this in my 2003 Cavalier too and both sound fine. Use T-taps for the rear speaker wires to your line out converter. You shouldn't have any problems.

What is the best place to get a remote signal?

roccityroller

the back of the head unit.

A remote signal is a 12v signal that tells the amp with the headunit is in use. Look for a wiring diagram of the oem wiring harness and go from there.

in lamens terms the remote wire will conrol if the amp circuit is complete. if the remote has power the amp will turn on. if it does not have power it will not turn on. find a wire in the back of the head unit that has power with the head unit is on.

the rear speakers that you t off of are 2ohm though right? im just trying to figure out if my sub and amp will work with a 2 ohm configuration

That's all well and good except there is no switched 12v wire at the back of the head unit on the Cobalts. The factory head units get their turn on signal from the LAN data signal.

To the OP: you will have to get a remote signal from the fuse box. Most people tap the sunroof fuse (your car will probably have a sunroof fuse even if it doesn't have a sunroof).

good to know. I wasn't aware of that, i haven't messed with the factory audio. Thanks for the information!

I just ran a switch for the amp because i didnt want the subs on all the time heck i hardly ever use 'em. Depending on the amp i didnt even use a line out converter i just used high level inputs that came with the amp and tapped right into the rear speaker line. Sounds great!

I think your best bet would be to use the retained accessory circuit in the car that way when you shut the car off, the amp will turn off with the deck rather tran thekey. this will eliminate turn on thump also. the wire is a thick blue wire in the passenger kick panel. please test the wire but it should remain 12+ when you turn the key off until you open the doors. just a thought. good luck

yeah, reason why I asked where the best place is cause i knew there was nothing on the back of the stock headunit. thanks for the replies

Bandit2941

Or you could just tap the sunroof fuse and not have to blindly probe wires
