Mikey B's Arc'd out Escalade
Another happy SoundSational customer.
Here's how the Caddy arrived.  Stock wheels and
factory system.  
Eclipse AVN6620 touch screen navigation
unit w/Bluetooth and ipod interface
ARC Audio KS6.5" Components
mounted in the factory location.   
2-ARC KS1000 amps power the 4-15" subwoofers
while a KS300.4 amp powers the highs.
4-15" ARC subwoofers
produce glass shattering bass.
