Pinoneer DEHP2000 and 12" Sound Stream

[95mustanggt]

I have a Pioneer DEHP2000 deck which I've lost the manual for.

My wife has a 12" sound Stream Sub woofer (boxed) and an Alpine 4X25W +80W sub. I was thinking about adding the Alpine Amp and using the 80W sub channel to power the 12" sub to my 95 GT.

Question: I have the Mach 460 Sound system. Is there outputs from my deck for this AMP (like I said, I've lost the manual. If you know where I can find one online PLEASE let me know).

I know the 80W is not a lot for the 12"sub, but it's more bass than I have now.

Thanks.
