Alright I'm going to be getting an explorer this week and wanted to see what people thought of my possible setup. I am going to use a 4 channel amp for my highs/mids and a 2 channel amp to push a single dual voice coil sub. Probably a 1000 watt 2 channel amp and maybe like an 800 watt 4 channel. Right now I'm thinking of looking to get 2 pairs of MB Quartz 5.25" components and am now looking for a sub that doesn't take a huge box, preferably a 12, and doesn't cost $500. Whats a good sub for the price? Anything else that compares to MB Quartz's components for less money? How is Infinity? Let me know. Thanks.
