You mean the PP 86DSP? That was my first choice but it couldn't work on my car. The two extra channels could prove to be useful, but I don't know if they would drive the mids in the doors or the carvers. Driving the carvers would be absolutely pointless imo. Another point to note is that the 86DSP only produces 55w per channel, so you may have issues with higher-end woofers if you eventually decide to upgrade.
