I am looking into amping my speakers (if you saw my other thread, you know what i mean.) What i will be powering is going to be a set of REV's up front and then either a set of eD 700's or Tang Band 6.5's, or another set of coax/comp speakers in the rear deck. My question is should i get two US. Two Channel Amps, or one alpine four channel Or any other brand. My maximum budget is 150, the only reason i linked to the alpine is because one is in the classifieds right now. any amp and/or rear speaker suggestions would help. I will not be running subs, i am afraid it will be to much of a drain on my current electrical system in my car!
