Alpine MRD-Mxxx mono sub amps? Good?

[sqguy 0]

I'm looking at an alpine class D sub amp and wondered if anyone has used them. Its the smaller 301 but might maybe be large enough for me not sure. Anyway, it looks to have a parametric eq in it even...that would be nice. Anyone used them?

I guess I'm wondering if one would work ok for my sort of SQ system, instead of an older class AB that takes more power. My kicker class d seems to work ok, but assume the Alpine is better quality yet.

I have used the M300, and my brother still has one. A buddy has the M1001 as well.

Good amps.

I can get a good deal on it....thinking about taking the kicker out and just going back to amps. That way I can use more quality on the highs, it just po's me this kicker is not working well in the 4ch. I can run it 3ch but that kind of defeats the reason why I put it in there.

The 301 is just a tiniy amp power wise. It's really got no go to it.

Right it is not that big, but my subs are IB anyway. May take out the 4 12s and see if 2 15s fit, more efficient ones, then try this alpine on those. It is mostly SQ but I like to feel it a little at times.

hopefully 350w @ 2 ohms is enough for that.

I've been trying this kicker 700.5, it is 420wrms @ 2ohm. My conclusion is that the high side I wanted to run at 4ohms x 4ch is too weak for me. Could bridge it and run the 8s (mid bass I want to put in), but not sure because it is hard to tell when it breaks up. The sub side is pretty good, but the 4 infinity DVC 12s could take more (& figured they would not, I was surprised). Infinity says half wattage IB so that would be 150rms, maybe they are right.

So I was looking at two cheaper 15s that are 99db, higher than the Infinity at 93db. The 4 subs and the amp; that baffle weighs a ton and I don't like it at all. That was one reason I went IB because it would be lighter than a box, plus don't have room. They hit the bottom nice though, and the high side will wash out long before they do. Maybe the two 15s would put out about the same (if the amp was the same)?

I can always pedal it and look for its bigger brother. I have some other 300/500/maybe larger amps I can try if the kicker comes out, but they are all class AB.
