I think you would be better off running with the MRD500. Being a class D amp it will be least taxing on your electrical system. And puts out a nice amount of power to run that 15!! Also the MRV 1507 is one rather large amp!

Also if you were to go with the MRV 1507 you would only be feeding your sub with 225 watts per voil coil as this amp isn't 2ohm mono stable.

Well are you just looking to run the one sub. Is there any chance in the furture you may want to run a second cause then you might want to look into getting that JBL BP 1200.1.

I only just noticed that you have the 2ohm version. So are you intending to run these subs at 1ohm? If so i'm not too sure if the MRD-500 is 1 ohm stable. I'm sure someone else will shed some light on that though.

MRD isnt 1ohm stable..... i actually got it on special price... i might have to use 2 amp to run it each at 2ohms...

Yeah that could be a way to go. Not entirely safe but a few ppl do it. Otherwise i would keep looking into that JBL if you can get it anywhere in this darn country!

well yeah, but at the moment i have to bridge my Sub to 4ohms and then bridge my amp to 4ohms load then i can use it for a while

i am still looking for some amp... and some stuff i am looking a really good amp that will feed my 15" 2ohms.... might need to get a 2 ch with 300w x2 @2ohms... something like...JBL is good..but just cant get it in australia.. Alpine MRD500 or MRV-1507 ? -- posted image. .

if it said on my sub DVC 500w and peak 1500w , does it mean each voice coils need 250w to run??

Yeah that is 250 per coil to run. Yeah it would all be a lot easier if we could get JBL in Australia.
