I still have a NIB Solid Audio F2500D. Only powered up once to test output, then put right back in the box. It does come in the original box with an owner's manual and bass knob.
This thing really is a monster, and uses the same board as an American Bass XD3000. Stats are as follows...
1200 @ 4ohm
1700 @ 2ohm
2500 @ 1ohm
3000+ @ 1/2ohm
I'm sure it'll do 1/4ohm for burps, so long as you can keep the voltage above 11V.
I'll accept trades for 3 used Batcap 2000's, 2 new HC2400's, 3 HC2000's or 1800's....or partial trade if you only have one. Of course, these trades figures are negotiable, and condition/age of the batts may affect what I'm willing to do as far as trading.
