Hi,
I'm torn between the Kenwood 558 and 308 units. Main difference is pre-outs. 558 has loads and 308 only one. As I have no intention to replace the stock amp, do I need the extra pre-outs on the 558 ? Also, I seem to remember that the OEM amp requires direct speaker outputs to drive it ? If correct, no requirement for pre-outs ?
Are the speakers behind the seats subs or just basic bass speakers ?
