Powered sub's

[RamAirZ]

I'll just take your word on it too because I'm looking at it from an RCA stand point. RCA's send the audio signal to the amp, the amp provides the power based on it and the subs resistance etc. Changing RCA cables wouldn't increase the power output, might get you a clearer signal path but measured output should be the same either way. In this instance I'm looking at it this way, the rear speakers output might be cut by 50% but why would the subs output be cut since it is only using those speaker wires to get audio signal and not power?

BINGO

The rear speakers will only be getting 1/2 the power that you were getting before. The powered subs will boost the power back up for it's own need ... but ... subs suck at pumping out mid to high range. You'll be getting plenty of base but you'll prolly hafta tweek up the treble a bit to compensate.

Are you starting to see why sound engineers get paid so much out in Hollyweird?

BTW, I'm not sure what you mean by RCA cables. Typically audio signals are on wires with RCA connectors and line signals are on wires with mini-phono jacks. The connectors make very little difference on resistance until you get up into VHF & UHF (i.e., shielded cables).
