Your power cap will do beans, sorry. You need to give the technical data of the subs to someone who knows what they're doing. It's about matching the sound wave with the length of the box and the resonant frequency. . It's not an easy thing to just work out. Plus you'd need a box the size of the boot

try getting hold of infinity on the web and they ul give you the correct specs for the box as most 12" subs from different company's have different dimensions and do you have the correct sub for a box or is it a open air sub for a saloon |

What RMS are whose amps? You can get cheap amps with around 100w RMS and 1200w MAX and we know which figure goes on the box. |
