I currently have a Alpine CDA-9884 HU installed, 4 6x8 Infinity Kappa components, a Kenwood 2 channel 1000W amp, and 1 12" Kenwood 1200W sub. Components work fine with the HU, my amp powers on but the subs dont kick at all. But my friend plugged my subs to his alpine amp and they pumped heavy. Btw i have a 99 Taurus SE no MACH system. I cant figure out the connection problems.
