Hi, this is my first post, even though I have been lurking for a few years.

Recently, I added the following upgrades to my car:
HU: Pioneer DEH-P350
Front doors: Kenwood KFC-X688C
Rear doors: Pioneer TS-680R

These upgrades are a dramitic change, compared to the "premium" sound system that came with my car (98.5 SVT).

I am not sure if my next upgrade should be a sub, or an amp, as my system sound good now, but I am missing the bottom end.


Thanks,
