post the voice coils of the subs and budget for amp recommendations. as for box, definately ported, thinking 36-40hz. for those would be fine.
have you also already done the charging system upgrades for your vehicle? cause those are what, 1000wrms, and that's alot of strain on a stock electrical system.
dual voice coils as far as budget i just need a few recommendations because i can get amps for cheap but like 500 and no i have not done the charging system upgrade can you give me some info on that
