Anyone have experience with underseat subwoofers? I want to fix my shitty bose system by changing the tweeters and adding subs but i'm not ready to give up space in the boot/trunk. So the answer would be an underseat subwoofer. Does anyone know if one fits?

 

How often do you have 4 people in your car? I didn't want a sub to take up trunk space and I have never had more than 3 people in the car. I ended up putting the sub on one of the rear seats. It does have quick disconnects in case I need to carry a 4th person I can just throw the sub in the trunk.
