Building a bass system for your vehicle is more complicated than buying some subs and hoping for the best. You've got to get the right sub for the size of your vehicle, the right amp to provide the right amount of power, the right box for everything and the right wiring to provide the right amount of current. Man, you just want some bass! How can you make this easier? Belva BPKG212v2 Amplifier and Complete 8 Gauge Wiring Kit Enter the Belva BPKG212v2.
