Kicker, Bose, Audio Pipe, Kenwood, Pioneer. All seem to be good brands for speakers. I ran two Sony 6"x9"s and they were ok, not exceptional. They sounded very crisp and clean, but were not able to go too loud. Im not sure how Audio Pipe is on speakers, but they are exceptional on subs, as I had two 750w 12"s. As for the amp, I used an Autotek and was pleased with it, but again, it was not incredibly exceptional, but was $150. Just stay away from Pyle for amps. Basically you pay for what you get. The more you pay, most likely, the higher quality.
