Well im having a hard time making a decision on what to purchase i could use some help im looking to spend around 500 and will either be powering a revo or axis not quite sure yet all opinions appreciated

so far ive looked at a few amps a t2000, powerbass 3000, xxv thor, xxv collosus, and the new ia 20.1

Can't go wrong with sundown amps.

yah i know that but if i went that way i was looking at the 3000d because i want to increase power fom my md2d and the 1500 is the only one in my price range

I've heard good things about IA but never seen or used one personally.

yah so have i im just looking for some info on if they will do more than rated i need something to run an axis

The IA is on crazy sale for a little bit longer, if that helps at all.

You won't hear that extra couple hundred watts when you're already around 2000. Plus if you build your enclosure a little larger you can still hit the mechanical limits of the sub with a lower powered amplifier.
