Dispute it!!(it appears to be wrong)

B/c I just checked the specs and the only preamp output appears for a potential powered sub.

I can't believe that they're still making HU's without preamp outs......

He would've had to buy the 9831 to get a preamp out, and that woulda been a 4 ohm out.

The fosgate amp pretty much needs a fosgate hu, because they are the only ones that I know (off the top of my head) come with the 2 ohm output.

I'm sure he'll be fine as long as he bypasses the amp.
