How many of youhave upgraded your 15' audio? How did you add a sub? which door speakers?

 

Just dropped in a 10" kicker L7, and have two pair of cerwin vega v465 door speakers on order. Running an eclipse ea3422 for the door speakers and fosgate PBR500X1 for the sub. Running the sub was incredibly easy. I pulled the head unit, installed a LOC by splicing in and soldering wires, tapped the radio on wire, ran power to the battery through the firewall, and then grounded out on a bolt in the trunk to the body.

All in all the sub took around 2.5 hours to do, however i had to DMM all of the wires and pins, plus the head unit is a little bit tricky to remove if you don't look it up first.
