Yes. If you were to bride one set (for example rear) you could run it at 4 ohms only, which im assuming is 140 watts x 1 bc you would be bridging channels 3 and 4, so it would be only 1 channel then ( i think...its late)

If you wanted to run the other 2 channels, you could run them to 2 ohms.

TEDD

damn, now im not sure.. b/c the manual says 140Wx2 @ 4ohm bridged. which probably means when all 4 ch are used combined to make 2 channels. im tryin to figure out what the RMS rating will be on the mono channel in 3 ch mode. :-/

right. 2 channel mode
140x2 @ 4 ohms bridged

4 channel mode would be
70x4 @ 2 ohms, 35x4 @ 4 ohms

3 channel mode is
140x1 @ 4 ohms bridged & 35x2 (both @ 4 ohms)
or
140x1 @ 4 ohms bridged & 70x2 @ 2 ohms

why is it only 35Wx2? the amp is rated at 50Wx2. and i dont think its one of those amps that overrate. its eclipse.

ok 50x2. it's an unregulated power supply then. it doesn't double it's power at half the load.
no big deal.
I was going based on the one spec you offered. I didn't look up the ratings.

sorry for it to sound like i was attacking you kiki.. it was meant to sound more of a question of if you found it was only 35x2

no, I didn't take offense or anything, I just meant I based the figures on the first bridged numbers. if it's 35x4 @ 4 ohms and 140x2 @ 4 ohms bridged, then that's what you'd get in 3 channel mode.
35x2 @ 4 ohms for front speakers
140 watts x 1 for the sub (4 ohms bridged)

Sounds like a stupid question, but I honestly dont know the answer.
What terminals would you wire to when using the 4 channels into a 2 ch bridged configuration? ?

Would you sum the FL and FR into 1 ch and RL and RR into the other channel?
Or sum the FL + RL and FR + RR??
