what is a better amp the alpine MRV-F345 or the jl audio 300/4 their around the same price. also the mrv says 75x4 at 14.4v, so what do you think it would be at like 13.5-13.9v

Yeah the only Alpine amps I've liked were the old V12's and they needed a good amount of input voltage to perform well.

As far as what the Alpine would produce at 13.5v, it depends if it has a regulated power supply or not. Most likely its unregulated if they're quoting a power figure at 14.4v so you probably would get a lil less power at 13.5. Whether you'd notice the difference is another story.

All things being equal I'd still say the 300/4 would perform better and more reliably.

I'm glad people are no longer worshipping Alpine amps. I remember a while back, everyone liked/wanted them.
I might've been the first to say they were way overrated and over priced. Although JL is over priced, it's still great amp.
It's good to see more open minded thoughts/opinions now.
