i have a rockford punch 100a that i want to put in my car along with two pioneer 12's how do i go about hooking up the amp with my stock hu? should i tap into my rear speakers or is there some kind of output on the radio? and where to hook the remote wire?

 

you can hook a hi/lo converter up to the speakers to give you the rca connections you need. As for the remote wire you shouold be able to find a 12v ignition wire under the dash usually a pink wire in the ignition harness under the dash.

 

You can hook up both your LOC and remote wire to the radio harness too if you want instead of going to the accesory wire under the dash.
