Has anyone made any aftermarket improvements to the EX audio system? It sounds pretty clear, just doesn't have any guts down low. I am wondering if there are any decent subwoofers (decent, meaning not the Honda one) that will fit under the front seat. Is it worth running an amp from the factory head unit to the factory speakers?

Any other suggestions?

 

you shoud replace all of your speakers with Rockford Fosgate Punch speakers. The only thing i can think of that will fit under your seat is a Buttkicker (theres a link below), its most commonly used by drummers, but it sould work in this case. If you are willing to give up some space, I recomend a single Rockford Fosgate 12" P2 subwoofer in a bandpass box. As far as an amp, i think rockford fosgate makes a small mono amp that would work if you only want a little more bass.
