Had to upgrade the "system" the factory setup is great but I always try and push for a little more.
Kicker L5 10"

Kicker 400 amp, throws out around 470 watts.

And the tsunami wiring kit, cost around $250.
Beltronics 995, its great!

Since I've deployed I have purchased the Scangauge II and the GlowShift triple gauge pillar.
