cuz i wanna know if its cheaper to get the 2 subs for $182 each and the box for however much it is or get it all together for $730 but i think everything together is a little expensive
You can usually find fairly simple ported boxes for L7s at any car audio shop, prefabed for about $150-$200. If you are looking for a bandpass, it'll cost a little more ($300 range)
