Sorry for all of the questions on the forums. I recently installed my first audio system into a 2000 Chevrolet Tahoe with the 9 speaker including a sub woofer and stock amp. I decided to upgrade and get the Kenwood KDC-BT558U headunit along with a precision power ppi 900.4 powering 2 Infinity Primus PR6500cs component speakers and finally a Image Dynamics ID12 D2 V.3 in a sealed 1.5 cu ft enclosure. I have the rear channels bridged to power the sub. Now for the PROBLEM there is a switch on the amp that goes between 4ch and stereo. In stereo the subwoofer plays, but very quiet and has highs in it. In 4 channel, which I think is what it needs to be in the sub produces nada only a stock sub in the side plays that i thought i didnt even have hooked up. Is there something i need to unhook at the headunit or what? I have no clue and am no professional with this. Could somebody more experienced assist me. If so that would be great. If you need any more info let me know. Thanks for your time. Jeff
