hello, im looking to add a sub and an amp to my 1991 suburban. i listen to music with lots of double bass (Slipknot, Chimaira, In Flames) i want it to be loud, very loud but still clear and i was wondering what would work the best. i was thinking about a 12" sub and some kind of amp. space is not a problem yet budget is. i only have about $350-$450 to work with, maybe a lil more. thanks for any suggestions and advice
