I have two PG RSd65cs in the front and two Infinity 462.9cfp in the rear side panels.

the RSD65cs is 4 ohms 60 watt rms

the 4629cfp is 2 ohms 60 watt rms

my question is can you configure a multi channel amp to power all four or do I need to get 2 amp.

thanks a ton

yes you cna. if you find a 4 channel amps that is bridgeable to a 2 channels @ 2 ohms
you can run the PG's on two channels then bridge the other two speakers parallel across channels 3 and 4
but the amp has to be stable at 2 homs bridged.

Also some 4 channels have a 2ohm load rating and a 4.
you might be able to just run each speaker in its own channel but two speakers will see more power. i would make that the fronts

most , if not all, 4 channel amps are 2 ohm stable per channel. just turn the gains down on the rear speakers to bring your soundstage to the front.

if youre on a budget, profile california amps are well worth checking out.

Leave the back speakers out. Best thing you could do

I use all 2 ohm speakers mainly because of the deals I can get on them and the increased power benefits. I have 2 profile ap1040s. They only run about 85 BNIB warrantied. The build quality is surprisingly good.... the crossovers are way better than amps in its price range... and they sound decent.

80x4 @ 4...125x4 @ 2...225x2 @ 4
