You wont accomplish anything with stuffing the sub with pillow fill. If anything, it will be worse.

Also the subs & amp are 2ohm which is why they are wired the way they are. If you wire the amp up to a 4ohm head unit you will risk blowing the amp, HU, speakers or a combination.

The Bose sub shelf is designed as a ported system. If you want to use an aftermarket amp and/or HU then you need to use 4ohm speakers....NOT the Bose ones. You can get 5 1/4 subs in many component systems and run new wires to the amp using the sub channel or a mono amp.

I have 2 bose subs left from an upgrade I did if anyone wants them, but they have to be used with the factory amp & head unit...wont work right with aftermarket.
