i just bought a hcca 15.4. i need help with the size of the enclosure, what amp would best work, and anything else that would help me get the most out of the sub. i drive a 97 2 door cavalier. so i have to build a custom box to fit in my trunk. the trunk is roughly 32"W, 24"L, 18"T. i could build a box to fit but i know if i got the right dimensions for a box it would sound better. i also don't know what amp i should get. i was thinking a rockford t1500. i don't need a super loud system so i figured it would probably work. anything else that would help me out would be much appreciated.
