Run a dual 2ohm sub on it. Bridged parallel. That will give you your max. 600rms/1200max

There is nada wrong with your preamp and changing it will accomplish nothing. If your channels are allegedly clipping it is due to the fact that it is being over driven. A bad preamp could not over drive your amp!
Have to be careful with tone controls at high levels. Every 3db increase compels amp to double power at that frequency. So if you are blasting at 2000 watts and you boost a control by that amount, your amp will put out 4000 watts and clip. If plus 6db then it is 8000 watts!

Overdriving the output can cause it to go into protect mode. You will not be able to restore normal operation until failed components are replaced.

That will require an amplifier and enclosure, as well as "audio out" connector(s) on your TV or set-top box.
