I'd like to get some smaller subs for the cabin because I hate having a trunk full of bass and tons of weight from (big) boxes and stuff, but all I'm finding is cabin air filter replacement and stock sub replacement stuff.

 

you're SOL unless you make your own

an 8" subwoofer can fit under the seats

I used this sub: https://www.sonicelectronix.com/item...nd-SWS-8X.html
and this terminal cup: https://www.sonicelectronix.com/item...minal-Cup.html
stuffed the box with padding, it's about .22sq ft and the sub is "optimal" at .25sq ft in an enclosed padded box

This amp was driving it: https://www.crutchfield.com/S-4fDZGx...KAC-M3001.html

I was very happy with the results. i just wanted a little low end and i hate giant trunk rattling subs. this was perfect and took up no space

 

Wow never seen someone set out to put subs in the cabin. I have a 12 inch in box in truck and it could hold a party in a huge empty car park. Looking forward to seeing this.
