okay so here is the issue, I have my toy car's motor coming out the shop in the next few weeks. I need to fill space in the car with my stereo. I'm planning for 4 Powerbass L-15s in a ported box. Powerbass recommends 6 ft3. with my experience with the "recommended" box size, all the companies usually go a bit small. can I go to 7 or 8 ft3 or is that too big? should i look to go with just 2 b/c of the size of the vehicle? any help is welcomed.
