Ok guys, since I have a regular cab and I'm not looking for a huge amount of base. I think I'm going with this enclosed sub from pioneer. It will fit and not take up all my room and give me all the bump I need. Amazon.com: Pioneer TS-SWX251 10" Flat Subwoofer with Enclosure 800 Watts: Car Electronics I don't know a whole lot about subs and amps, besides what I have been reading online. So I am looking at an amp to power this unit. I know it is nominal 200 watts (RMS) and a peak of 800 watts. From what I have been reading it would be best to go with a 2 channel amp and bridge it. I read that mono amps go better with 2 ohms and this one is 4 ohms. Anyone have any suggestions on an amp that would go well with this? I have found a few but I am wondering what amps I should go with. I know you are supposed to match them if you can, but would a 500 or 600 watt amp work?
