I don't recall this series being one of phoenix Gold's outstanding or exceptional series, but none the less a solid amp. So either sell it here and take the highest amount or off to e-bay where you might start the listing around 175-200. At least that's what I would do. Here is a link for a four channel on ebay..https://cgi.ebay.com/Phoenix-Gold-QX-150-4-Car-Audio-Amplifier_W0QQitemZ5820116085QQcategoryZ79820QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

What did you pay for it originally?

Picked it up from a friend on trade. I gave him my MTX251D and $75. So basically $200.

This amp has been excellent. I have it running 1 S12L5 in a vented enclosure at 2ohm mono and it never even gets luke warm. I'm just thinking of increasing my power to a 1000 watt Memphis amp. Don't know yet cause I like this amp. just wanted to get a feel for what its worth. Apparently not as much as I thought. :)
