    3. Description/Condition:

    It is mint now, it was blown. Repaired by 807tubenut on here. He beefed everything up that RD half assed on. tubenut is now an authorized crescendo dealer and his website is ampenstein.com Amp is in full working order, i took a video of it running 2 of my 4 subs (at 1 ohm). One of the mounting tabs is bent upward, you could probably put it in a vice or somethin and flatten it.

    He is warrantying for 1 year, and the warranty is transferrable (you just have to register the serial number with him and the warranty stickers are still on there)

    Here is a thread with pics on what he did:

    I do have the bass knob, not sure if it works. It'll be included but you need to get a 5-pin phone cord.
