Soundstream Reference 644S/Alpine MRD-F752 5 channel - which one is better quality??

[redcalimp5]

I have one of each amp mentioned in the title, and wanted to get some opinions on which amp would produce a cleaner sound through a set of components in the front, and coaxials in the rear?

Both amps in 4 channel spec are 100X4 @12 volts.

Thanks!

All things being equal (gain, distortion, etc) you won't hear an audible difference.

If they are both similarly rated, then pick the one that has more features, fits the install better, or was cheaper.

That Alpine is a Tripath, right? Well you can expect a lot more efficiency than that SS Ref amp. If you ever plan to run a sub, then that's something to take into account.

PLEASE don't put coaxials in your rear doors!
