Just another one of those "is this amp compatible with these subs" threads

[Umbra]

I've got two Rockford Fosgate Punch He2 (12") subs currently powered by a Kenwood KAC-9103D. The subs have a power range of 100-400W RMS each and 800W peak. Since the subs are 4 ohm DVC subs I've got them wired at 4 ohms as I'm not comfortable wiring it to 1 ohm, as there's some debate to whether or not this amp is 1 ohm stable and the electrical is stock. So the amp puts out 500W RMS @ 4 ohms to the pair, so that's 250W RMS each?

It's nice, but there's this cheap Alpine MRV-1507 on Craigslist that I've been eyeing. It's definitely an older amp, but it seems the people who've owned them in the past love them. I can't find a nice spec page like I can for the other two, but it looks like it does 900W bridged @ 4 ohms (and even more according to some pages I've seen where they were bench tested), so that's 450W each RMS?

My question is this: could I use the MRV-1507 to safely run my subs, or is it too powerful?

Due to the nature of music and factoring in rise, you'll rarely ever see the full 900 watts. So, yes you'll be fine to use that amp. Just make sure to set the gains properly, a clipped signal will kill those subs.

Here's a manual with full specifications from Alpine. http://vault.alpine-usa.com/products/documents/OM_MRV-1507.PDF
