6x9 speakers with a nice base sound wanted

I have a pair of Pioneer 6X9 tri-axles under the rear shelf.
I think they have as good a bass response as any 6X9.
I want a Bazooka brand bass cannon. The smallest one they offer will suit me. These have their amp built in but powering it is optional.
I owned one years ago. The amp in it was fried. I used it with the stereo in the house for a long time. Wish I hadn't sold it.
