I have a pioneer deck that only has front and rear outputs. I bought a ZX300.1 Kicker amp, and Im wondering for the time being, until I get a new deck, if it will sound good using the rear outputs?

 

It will sound okay, but without a sub output you wont be able to easily isolate the low freq. I have one of my subs run off rear, and one off of sub output, and sounds pretty nice. It makes up for the lack of midrange of the stock door speakers.
