Well, speaker level inputs aren't a factor, because that particular amp doesn't have them. I was considering that model for when I upgrade my car audio. 85x4 on 12.9v - how can you go wrong? Just the thing for a kid with a Civic who doesn't want to go overboard like everyone expects him to.

Unfortunately, I know next to nothing about setting up an amplifier; I still have my empeg running through my crappy CD receiver (AUX IN is 1/8" stereo jack on front panel; blech).
