10", 12" or 15" sub in box under $150
 

looking for one sub (preferably 15" or 12" but maybe 2 10" but box must not be huge. looking for smallest box possible but must thump hard with deep low bass. maybe bandpass box? doesn't have to be new or pretty but must be able to be played for a long time without blowing or clipping. i will be running a 500 watt alpine (mrpm500) so it wont be too crazy. will be tested before buying. looking to spend under $150
