None of the above, MB Quart Onyx OA1100.5, zero regrets..

What do you like about it over comparable amps?

Wattage, zero noise, no turn on pop, very loud and extremely clear..

The PDX has more power (rated), and I really like the way the wire plugs. The footprint is nice, and with the exception of very mild turn on noise, they are very quiet. I don't know what the price is on the MB Quart, but it's less powerful than the Alpine, looks bigger, and the wiring is a bit less convenient.

At 2ohms, it looks like the MB has more power, but for 4 ohm speakers the PDX is in my opinion a better option.

The OA1100.5 does make more power, 150 x 4 @ 2 ohms + 500 x 1 @ 2 ohms.

IDK what you mean about wiring difficulties, it's pretty straightforward with power and rca's on one end and speaker out on the other side..

It's also a lot bigger than the Alpine, the OA1100.5 is 16" wide x 9-7/16"D x 2-1/4"H.

And the MB Quart symbol on top of the amplifier is backlit and glows red when the amp is turned on, it looks tough..

It also has pre amp out RCA connections for daisy chaining multiple amps.

It's got all the bells and whistles

.. With regard to wiring, I said "less convenient" not "difficult."

My bad, it was not my intention to misquote you..

.. I think more attention should be given to 5 channel amps especially people interested in upgrading the entire sound system; since many of the best factory systems are under-powered.

Keeps things nice and neat - OEM HU, LOC/DSP, 5 Channel = Done

My father (RIP) taught me the K.I.S.S. principle, keep it simple stupid

A 5-channel amplifier is by far the easiest and most foolproof way to build a 3-way active system..

75 Wrms per channel is more than enough for me but only because my system is full-active, on the same if I was using passive components I would probably want closer to 125 Wrms but then I would only need 2 channels plus the subwoofer so I could just bridge the 4-channel portion..
What we discover is that it's real easy to buy more power than we ever need and finding speakers to handle and fully utilize that power becomes increasingly difficult..
It really all depends on system restraints but I can run most people out of my van with my current configuration before the volume knob makes it to the 3/4 mark..
You know you're doing something right when the passenger is covering their ears with their hands while wearing a **** eatin grin on their face, I just smile and turn it up a lil bit more..

Pick one with a bandpass filter and be done with it..
