[QUOTE="crewd, post: 326207, member: 550460"] I've got an Alpine 7854 HU. Unfortunately it has only one preamp out. I need to power four door speakers and a 10" sub with HP and LP capability. Am I correct in assuming that because the RCA preamp out offers no fader control, I'm better off buying a 4-channel amp (as opposed to 5-ch) and running the door speakers in 2-ohm mode (front & rear connected) and the sub as a bridged 4-ohm speaker? Thanks, Jon Alpine 7854 CD Receiver (amp inserted here) 4 Polk DX7s 6x8" (4-ohm) 1 Polk GNX104 10" sw (4-ohm) [/QUOTE]
