Hello all, I've been out of Car Audio since probably the early part of the 2000's, but I recently got fed up with bad quality audio and decided to put together a reasonable priced SQ geared system. I'm going to be powering 2 Eclipse SE8365's and 2 MB Quart OKC116's. Both sets are rating 80W Peak, 40 RMS. I've been looking at lots of Amps from the Infinity Reference 475A, to the MB Quart OA400, OA600 and OA800's. I'm not sure if these amps are good for my application so I'm reaching out. Back in the day I'd find the first 4 channel Eclipse Amp I could find, but they are not too common anymore, neither are the old Nakamichi USA made amps I was also familiar with. Any suggestions would be appreciated. Thanks
