Re: What's the state of the medium-output subwoofer amplifier market?
There's plenty of competitors, fret not. Most warranties don't matter when you buy the cheap stuff though. Crescendo is solid, Sundown is good, Treo is good. All the internet brands are making solid stuff. Skar, DD, DC, Incriminator Audio.
I think the weakest link right now is your box. A sealed enclosure is often said to rob 50% of the potential output. You're not going to notice much of a difference (if any at all), between 1200w and 1600w. Maybe you'll notice something at 2,000w, but at that point you might start needing electrical upgrades. If you buy some of the pricier amps in that power range, they tend to be more efficient, and may save you from electrical upgrades.
