I upgraded to Boston Acoustic speakers front and rear but don't have much bass.

I tried adding a 6-1/2 Bazooka tube but could not find a place to mount it.

Would you recommend adding an amp to bring the bass out of the speakers or adding a powered sub?

I don't want to lose storage under the seat or interfere with the ability to fold the floor flat for hauling stuff. I have a power driver's seat and would be willing to relocate the tire changing stuff under the passenger side if there is something that would fit in either of those two places. What about behind the rear seats?

Can anyone offer a solution to help fill in the missing bass?
Add an amp only?
Add a powered sub?

 

You could replace the center console with a box and mount the lid of your console to the top of the new box. Build it as big as you need. I went long and tall. I have 2 12's in the center console and 2 12's in a fox box...
