FS:MTX Thunder 2150x 2300x 4300x Old school power

[vwtoby]

I have a MTX Thunder 2150x, 2300x, 4300x for sale.

I have for sale a little collection of old school goodness.

Sourcing these amps took me a while, and they are all in very nice condition for their age.

I am reluctantly selling due to bills to pay, but I am not looking to be low balled on them either.

Excellent sounding old school power house amps, ones that have been a favorite for many for years.
