I have a channel on my amp that I am not currently using, and I am looking to build a sub. So, what I am wondering is this. Can I use this amp for my sub? I have been looking over old posts here, and I have seen references to a rumble filter. I would assume that amps intended for use with a sub would have this filter, and other amps would not. Do I need to do anything, or are there any potential concerns, with my proposed project? T

Other than adequate power and a low band pass filter (crossover) I can't think of anything. Both of my subs are passive and share channels on a two channel pro amp. Works ok for me.

If you build a sealed sub, you don't need the rumble filter. If you build a ported sub, you just need to be aware that frequencies below the tuning point will push your sub way too far.

I ran my sub with a regular receiver for a while, it worked fine. Just be realistic with your volume level during extremely low bass signals.
