My KAC9105D wont turn on? i had this amp stolen from me a week ago, purchased a new one and hooked it back up to the same wires that had been running the old one the exact same way, and it just lies there lifeless..im at a loss as to what could be the problem

I think you are good to go. Those are options, not mandatory.

Tipical for that amp.Did you buy it used?

if you bridge it i believe you run at 4 ohms instead of 8 even if the subs are wired together i would not bridge it for fear of blowing the subs. if you where to bridge it it would be the left channel on one terminal and the right on the opposite terminal. but i highly advise against bridging it as they are wired together. its running at the proper impedence NOT bridged.

First of all, how are your subs wired to the amp. Make sure your amp is not bridged or you'll fry it, it only has one channel. If that doesn't work you probably already fried your amp.

you rca hookup, back of cd player is rca out, at the amp it is rca in, make shure you hook up blue remote wire, also make shure you have a good ground if not amp will not turn on. if you run wires make shure you run power wire down one side of car and remote and rca down the other, This will keep all motor noise out of system.

Yes it is. it runs to the blue and white striped wire coming off the head uni.

it might be ur ground check the gound wire

make sure you run your ground and power wires on one side of the car and the rca's on the other, keep them sepparate. if you have all wires running to your amp(rca's/12v power/remote), then you run the chance of either getting interference from the alternator, or if you have a pinched wire(usually by the door step) it may short with your battery wire. Double check your rca's and make sure they're ok and also check for corrosion on your wires.

on the back of the stereo you should have an rca inputs in the back, it should say either rear, subwoofer, or non-fade. all of these are acceptable, run rca's to the amp from the deck.
also on the deck in the wire harness is a blue wire with a white stripe.
hook a wire up to this and run it to the REM. terminal of your amp. this wire tells the amp to turn on when you turn on your key.
these are the only two wires you hook up the back of the stereo.
hope this helps
