I have 4 X8 V.2 D4's in a ported box. Im looking for advice on what amp to use and should I drop them to 2ohm? And should I run them off of 1 amp or 2. And what amps are recommended. Help me OB1.

First thing comes to mind is why didn’t you figure all this out before you bought equipment ???

Well I though I had. But obviously I had made a mistake in my caculations. Mine you this isnt by far my first install. But is my first experience with Sundowns and A system with 8s. Im used to running multiple 15s,12s,10s ect.

Is your enclosure optimal for the drivers and custom fit for your vehicle ??? 

I’m not a bass head so please don’t troll me.

No difference between 8s or 15s in the questions you had.  First enclosure and cool specs are needed
