An amplifier that does 37.5x4 at 12v, probably does around 50-60watts at 14.4V. So, it should be equivalent to amplifiers rated around 50-60watts RMS per channel. I would try it without bridging first.we'll see how things go. the only thing is i'm a bit low on power for these things. my amp (mtx 6304) is rated for 37.5x4 and i have it bridged on rear channels for my sub. it says 150x2, and it supposedly makes that @ 12v and has no real ratings for 14.4v, my guess is probably around 180ish. i'll try them running off just the front two channels and then try with the channels bridged. hopefully that'll give me enough power to really see what these things can do!
so, yeah, in short, should be able to have a short review of my experiences with these up on friday. hopefully it all goes according to plan!
first things first, i installed my kdc-x995 head unit since my clarion cz500 screen went bad and i didn't want to deal with that piece of garbage. i had a lot of gripes with it and at the end of the day, decided it was worth it to just get rid of it and get a new unit. the x995 is awesome, btw, i love it. menus are easy to navigate, it's fast, and sounds good. tons and tons of audio adjustments as well, which is always great.
sound impressions are very good. the x995 has a 5 band eq and i cut the 4th band down to -2 to tame the tweeters a bit, but i assure you that it wasn't that they were harsh, just slightly overpowering. they were still very enjoyable, and this is with the 0db setting on the crossover; the -3db setting on one of my crossovers has a bad thread and i don't have the tools to rethread it, but i'm completely happy with the 0db.
