Hey guys I was searching on ebay for like 2 weeks now for a best subwoofer for me and Im not sure which to choose. At the begining I wanted to buy Audiobahn , but now most of you say that these sucks so i dont know my range is 200- 300$ for a sub. I need best SQ, but I wanted it to kick it hard to. I was thinkin about building a sealed box in my sedan BMW. Pleeeeasee help me!!!
