Crunch amp any good?

What do you guys think of Crunch amps??? v-drive...and blackmaxxx??? Thanks

I actually installed this one ( http://www.sounddomain.com/sku/CRUP804 ) in my sister-in-law's 2001 focus. It's currently running from the factory ford cd player and powering 4 infinity 5x7 2 ways. no sub though It hits pretty hard too. But the speaker's rms rating match the amps rms rating. So it's pretty clear. She's quite happy. so I'd say they are pretty good as long as they are used properly.Duane...

If you think you're confused, imagine how you feel.   

I used a crunck amp to run a couple of fosgate he 12's. i was pretty happy with it. they are a little underpowered though.
