Hey, I've been looking at Fi car audio for a while to help fix my BMW's horrible lack of bass. I was originally looking at the 12" Q but after reading around I decided that the BL would better suit my needs, I now am at this problem I know my trunk can fit the optimum box dimensions for the 10" and 12" but I dont really want to sacrifice all that space but then I want it to also to be hitting pretty hard. Also whats a good amp recommendation for the best price/performance
