Cheaper/Older powerful amp
 

Hi

Im looking for a cheaper amp that has over 3000 watts at 2 ohms or that is stable to 0.5 ohms something like:

MA AUDIO HK4000D
Audiopipe 3000d
Visonik 4000
Crunch 3000gp pro
Crescendo 3k

or anything else that is relatively cheap, used is ok must be in working order cosmetics no a huge concern

Thank You
