is everything wired correctly? grounded correctly? is your remote wire correctly installed?

Is that a stock head unit.

did you hook everything up right? amp needs a Power positive to the battery. a chassis Ground, and remote power turn on from the deck.

Have you hooked up the speakers yet. You should wire then up and see it the get output when the amp is on no matter which rca terminal you use. The owners manual should tell you which is from the deck to the amp and where it goes.

everything is hooked up correctly... do you think a new wiring harness would work?

is this thru a stock HU tho?

wow I have no clue what you're doing. by everything is hooked up correctly please explain in as full of detail as you can how everything is hooked up. IE Remote wire to HU to remote on amp, Power wire from batt to + on amp, ground from sanded chasis location to - amp. these 3 things are the most important, as far as the amp turning on that pretty much soley has to do with the remote wire being properly wired to the HU or an ignition location.

post some pics.

I was briefly reading through the manual and it mentioned some thing about a master/slave switch. Amp will not work if in the slave position.

Yeah some HUs have features you need to turn on/off in order to get your amp working properly. The more info you can give the more likely we can help solve your issue. model numbers on the hu,wires stuff like that.
