I am not sure what that amp is, but seems like a small one. Maybe time to upgrade ?

With prices on CDT, talk to Ross directly. You can find him under username Ross on here, and send him a PM.

You need a much bigger amp to run one of those Phoenix Gold subs, or two of any kind. Any of the subs I suggested are excellent for the money. You only have to decide how much you wanna spend. If I were you, I would get two subs, and any of the choices are excellent. Seems like Exodus and Sundown are your cheapest choices, and you will not be disappointed with either. CDT's are incredibly clean and tight, but CDT is not a cheap brand name, and I believe the lower models have been discontinued, and for 2008 only the high end stuff is being manufactured. I use 3 tens by CSS myself, and love them to death. Two tens is borderline output for me, but sometimes I like to blare it, so I need more for that reason. Like I said all these choices are excellent, and you will be happy with any two tens you choose. If you are on tight budget, it seems Sundowns cannot be beat on a sale thay are on now.
