Rockford fosgate question

Hey all im looking at geting a rockford fosgate punch 501x amp to fix my problem with every thing cutting out. Its a 4 channel 65w x 4 @ 4 ohms RMS. 2 questions about it

1. What do you all think of this amp herd any thing bad about it?

2. would it be possible to have 4 full range speakers on it and a sub or would that go right back to what my problem was before with every thing cutting out

Found it on a website some one here gave me thezeb.com i think it is for $200 the other amp i was looking at is a profile for 120 so i figured for a little more cash i could get the fosgate

The older fosgates (late 90's) were very nice, the quality has gone down over the years though. It would be better than the Profile, but I'm not sure if it would be worth $80 more. And no you can't power 4 speakers and a sub unless you put all 4 speakers on the front 2 channels and the sub on the rear 2 channels. But if you do that you lose the ability to fade to the front and back, if that matters to you.

thanks man your awsome

yes go with the rockford amp i have a 400x punch (2002 model) and its a really good amp but no i would run 4 full range and a sub
