I got 2 12" Kicker XPL's in the trunk of my 560 powered by a 400 watt Auidobahn amp. I took out the first aid kits for ports. You can hear me coming from a block away. The bass is awesome.
I recommend getting Kickers, Cervin Vega, or Rockford.

Supposedly Solaris bulbs are Piaa bulbs in different packaging with a new name. They had trouble selling Piaa's so they made up a new name and said they were better in order to sell them.
The pictures that websites post of new bulbs lighting up the road are fake... Different web sites use the same picture for different bulbs. Dont believe what you see.
