This is a super old post, but I thought I'd update it a little and see what info I could find. I pulled this Memphis audio amp out of my boat this past weekend, and replaced it with a Kicker 700.5 and the existing Kicker 200.4 to run everything.

The memphis audio amp mpodel number is 16-MCA2004. From what I found, it's a 50x4 at 4 ohm, and 75x4 at 2 ohm. 150x2 bridged. Sounds like a decent amp.

My original question on this amp was it's usefulness in powering my tower speakers. I swaped it out with the kicker 200.4 to run my tower speakers, and not much changed. I am thinking that the tower speakers are just kinda junk. From what I can tell, they are Skylon cans, but I'm not sure what speaker is in the cans (4 speakers total). I haven't pulled them out since last year, so I'll need to research those. They just don't sound all that good, more high range sound than anything.
