2 channel big power amp

[babsuhl81 10+ year member]

My question is I listen to a lot of metal that has fast double bass. It seems to me like my single sub can't keep up and it sounds like its trying to do 2 different things at once. I'm thinking a 2 channel amp would keep the bass cleaqner by keeping it separate. Is this right? Or am I doing something wrong? I plan on running a pair of subs. And any info on what kind of amp with like 500+ rms per channel. Any help is appreciated

its not gonna make a difference , because the subs would be summed into one channel .if your missing some of the higher bass notes then it may be the tuning of your box ,bass filter ,or even the wrong size subs

I'm talking about running 1 sub on each channel. Its running on a mono amp now and just doesn't quite sound right on some of the faster songs

Running two subwoofers in stereo should not help much if at all. First, it's common to record the lowest frequencies in mono to begin with. Second, even if your bass is recorded in stereo, I don't see how that would help. If bass is recorded in stereo, then the drum set is either in the center of sound stage (both subwoofers play equal content), on the left (mostly the left subwoofer plays, so the sloppy double kick is reproduced with a single subwoofer), on the right (mostly the right subwoofer plays).

Your problem sounds like you have run into a subwoofer with bad transient response, which refers to how fast the subwoofer responds to instantaneous changes in signal. This is something that separates SQ subwoofers from the rest, as you can't fix bad transient response by designing a custom box. A box design can certainly influence transient response a little. If you use sealed box, then box qtc should be at about 0.7, add or subtract 0.1. High qtc makes transient response worse. Low qtc makes transient response better, adds low end, but reduces power handling. Too many subwoofer manufacturers recommend a box that's too small for a resonable qtc number. I assume transient response could be made worse in a ported box as well if group delay is too high.

I can suggest and sell you an amp but I don't think it will solve your problem

Ok thanks. So when I build my system later on what kind of subs will be good for metal and rock music? I want the drums to pound my chest hard.

What is a low number when it comes to qtc?
