The CT 150 is a sealed design and chances are the original amp had some degree of boost in the 30 hz range. Since the measured response of the sub starts to drop off at 25 hz a replacement amp is going to need a sub sonic filter in the mid 20 hz range. The Bash 300 is up to the task if you're willing to change 2 resistors. The amps default subsonic filter is 17.7hz but it can be changed to 25 hz wth 2 db of boost in the 31-35 hz range.

With the sub being 15 years old I would not recommend a 500 watt amp.

The Bash 300 would be your only option for this sub due to the requirements I previously stated. You would need to find someone experienced with soldering, you don't want to make a mistake and fry the amp.

But first things first. Since the sub is old, what shape is the drivers surround in? Is it showing any signs of deterioration?

The BASH amp is good because it's easy to mod if needed. Being that this is a ported sub, it would be good to know what the tuning frequency is. That's a good place to start for the amp mods.
Agreed. If you could tell us the internal width, height, and length of the port it would be a tremendous help.
