I'm going to say 130 + shipping for each. Or 250 + shipping for both. I will take offers on these though because I'm not sure how much they're worth. PENDING SALE
2.- Directed 1100D. This amplifier works perfectly, but has some scratches on the heat sink. It's also missing one of the mounting pegs. It doesn't come with the bass remote. 150 SHIPPED, or best offer.
Specs:
Output Power at 14.4V (20 ∼ 250Hz):
1 x 425W @ 4 ohm (0.5% THD)
1 x 750W @ 2 ohm (0.75% THD)
1 x 1100W @ 1 ohm (0.9% THD)
S/N Ratio: >85dB
Freq. Response: 20Hz ∼ 250Hz (+0,-1dB)
Damping Factor: 50 (typical)
Fuse: 2 x 40A
3.- MTX Blue Thunder Pro 752. This amp is also missing one of the mounting pegs, but it works perfectly. I heard this amp is very underrated, it's suppose to do around 75x2 @ 4 ohms. 50 SHIPPED.
Specs:
Output Power at 12.5V:
2 x 37.5W @ 4 ohms (
2 x 75W @ 2 ohms (
