Im mostly looking for SQ. this will be put into an 02 Subaru Impreza WRX
MB Quart RSC 213 5.25" Separates
Alpine MRP-F200 4/3/2 Amp
Image Dynamics IDQ12 D4 V2 Subwoofer
JBL BP600.1 Mono Class-D Amp
wire the sub in parallel, and wanted the stock HU because it has a 6 disc changer and i want to keep the stock look. also going to be protecting all this w/ the Viper 500 security system. whats everybody think?
