This customer came to us asking to add a big bang to his little car, we were happy to help. We helped him pick out a system that included two 12 inch JL Audio subwoofers in a custom JL Audio box the CP212-W0V3. We then powered this with a Kenwood Excelon mono amplifier, the X500-1. This system was just as loud and clean as he hoped it would be, he was very happy with the results. This Fiat subwoofer system was recommended and installed by the tech crew at Audio Express 4509 E.
