The Power Amp is under the carpet in the passenger footwell. I don't think it has RCA jacks on it, just wires running to a connector block. If you read this entire thread, you'll see that SSSSly is talking about adding RCA connectors to the HEAD UNIT end of this wiring harness at the back of the head unit. Or at least to the adapter harness to preserve the integrity of the factory harness.
There have been a few threads about this very topic. Do some searches.
One more thing, in one of these threads, it was noted that the "pre-out" level of most aftermarket head units is 2.5 volts, and the xFire amp likes to see 5 volts. Hence a lower-than-expected output at the speakers.
