Question about amp for speakers

[Dyke]

Ive got 2 Inifinity Kappa 60.5CS for front speakers and 2 Infinity Kappa 693.5I 6 x 9s for the back. I was supposed to get a Infinity REF7540A amp for the speakers which is 520 Watt 4-channels. The person i told to order them online selected the wrong one (i would have done it myself but it was his credit card) and he accidently got a Infinity REF5760A 560 Watt 6-Channel Power Amplifier instead. What im basically wondering is if i can still power my speakers with that amp even though its 6 channels. Or would i be better off returning the amp and getting the right one.

If i bridge the speakers for all 6 channels will the quality still be the same and will it still sound as good if not better?

Yeah, why wouldn't you be able to use it? Doubt you want to bridge anything. You're just going to have two empty channels....throw a sub or 2 on there.

i was just concerned about the quality of the sound knowing that there is going to be two open channels

Doesn't make a difference.

im not even sure you can bridge a 6 channel to 2 channels.. normally its 4 + 2 so you can run the 4 speakers then the subs...
