Everything except for my sub works great. Looking to spend $500 tops between sub and amp. I want a 10" DVC sub that has some good sound and kick. I'm looking into the 10" Alpine Type R subs, they make them in 2 ohm and 4 ohm. The 4 ohm is like $10 more, but whats better? Then the amp. It says 600W RMS and 1800W peak. I can get a cheap Pioneer mono amp which is 400W RMS and 800W peak, is that ok? Then Matt and I would build a box due to great sucess from the last one we made. Anyway...opinions please.
