Yes, I know about tubes.
I do not want to have to remove the sub, though. The car is a daily driver that I just built from scratch to cruise with. My wife and I want to throw a few days of suitcases in the trunk and cruise. The space is at a premuim which is why I do not want to take away from trunk space. Removing the tube to go cruise for a few days beats the purpose. And as you may or may not know, once you open the top the bass goes out the window, per sae.
Looks like it will be going to the shop and let them have at it. I just thought someone here had already tackled the issue without throwing the big boom box in the rear seat.
I had also asked around about the Kenwood wOOx and the Infinity Basslink, but it doesn't appear as if those will cut it according to opnions that I have received.
