Ok, since it's my car in Taylorfades clamp test I'll chime in. These amps are in a Saturn Ion so there's not a whole lot of alternator in the car. It will only make 145 amps under perfect conditions. lol
I've had these amps in my car since June. They have survived low voltage. They have survived burnt coils. They are still running strong and I haven't had any problems with them.
I also have the 1200.4 Pure in my car. It's class A/B so it gets a little warm, but other than that they sound great and seem to deliver more than they cost.
My car with two 12s in the trunk turned in a 144.7 legal at it's first show. Considering we just put some 12s in a dd box that was just hanging out and is way too small for the subs I'm using, I don't think I can complain for the price.
I'm in the process of getting a more efficient enclosure built and making changes to account for rise.
In case Taylorfades article was too long for you. I am very nearly deaf and use Bone Anchored Hearing Aids. I turn them off in the car so these things have been well used beyond what a normal person would use them for. lol
