its your fuse box. i would bypass the fuse box and wire this amp directly to the battery via monster cable. make sure you attach a 30wieght fuse to the monster cable that is running from the battery to your amp. ground the amp against the trunk. scrape the paint of a section and drill a hole in the trunk. use this for the ground for you amp. this will fix the no power issue.
"how do i made amp ohm instead of 4" What? I think you're asking how to make the amp 2 ohm. If your 12's are already wired for 2 ohm, just connect the 2 leads to the bridged terminals on the amp. There will be 4 connections on the amp. One for each channel. Usually, the two outside terminals (one positive and one negative) are the bridge and it'll be noted with a line painted on the surface above the terminals. That's all you have to do. If it is overheating, you should put cooling fans on it.
Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.
