2 Ohm & 4 Ohm system

[99 sierra]

Hello,

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.
