4 channel amp doing 4ohm AND 2ohm

[Chris Braun]

Hi,

I was just wondering about 4 channel amps and haven't been able to find an answer to this question.

Can you run lets say ch 1 and 2 @ 2ohms for fronts (more power) and ch 3/4 @ 4ohms for the rears and vice versa (guessing not).

You can bridge ch's 3/4 of a 4 channel amp and not 1/2, but just want an educated answer.

Thanks and appreciate it!

I have a DC 175.4 running my comps. Channel one and two are at 2 ohm. Three and four are at a 4 ohm load. I have not had any issues with running the amp this way what so ever. As long as the amp is 2 ohm stable you should not have any problems.

Edit: cant spell

Not sure what 4ch you are using but in my experience you can bridge channels 1/2 together and 3/4. You could also run the fronts at 4 and rear at 2 or vice versa. If you bridge say the rear channels together just don't run an impedance less than 4 ohms.

^^ spot on

Thx for the replies. Kinda figured it should be ok. Won't be bridging it, this is about the 2 ohm JBL speakers I bought for my lil bro, and just general knowledge. Didn't buy an amp yet and just had the idea that the front and rear ch's on a 4 ch amp were separate but wanted to make sure. Possibly will be buying 4 ohm for the back (cheaper ones) later so was just wondering.
