My Busking Rig

Here's a busking rig that I put together. Pictured above is a Dual Car Audio amp (< $50) that delivers 150 watts to a 4 ohm Acoustic Image cabinet. The battery (< $20) is 12V 7Ah, the same battery used to power a Crate Taxi/Limo. I can easily get 3 hours of use out of this setup which is great when you're playing a double bass and need sound support in the NYC Subway.
