That seems about right..

For all those that are thinking of doing this in the future...dont bother. The stock amp cannot be bridged because it uses a common - for the rear channel which..after 3 wiring sessions I am convinced is simply chassis ground. On regular signal, turned all the way up, it barely makes some noise in the woofer, nothing even considered bass.

So what I did is I hooked up the stock amp to the speakers as before (still surprised by how much sound the 6 speakers make on that crappy little amp. I guess treble doesnt need amplification: it sounds the same with the stock amp 12W/ch amp and the 50W/ch kenwood). I grabbed the kenwood and attached it directly to the woofer itself and ran a 5 wire pack, splicing into the left rear speaker's output for the amp signal (Most bass signal seems to be on the left channel....maybe this is a coincidence but it always seems boomier on the left channel) . Amp wires run directly to the battery. The woofer is now a self contained unit.

Earthshattering bass and plenty of treble. I think it is either 150 or 200 watts when bridged and the gains are all the way down so I dont crack the paint or blow out the rear window.

Do any of you good folks know where you can buy pairs of wiring connectors like the stock harnesses have. I need a quick disconnect more elegant than wirecutters in case the mustang gets requisitioned for cargo hauling.
