The PW-1/0GA-50RD is a 50-foot spool of 1/0-gauge power wire for car audio installs. The spool is red. Buying by the spool is cheaper per foot than buying kit lengths for multi-amplifier builds.
1/0-gauge sizing follows the American standard, so it matches published amperage and run-length charts instead of the undersized 'true gauge' many cables use.
A 50-foot spool covers a full install with wire left over, at a lower cost per foot than buying pre-cut lengths.
The red jacket makes polarity obvious at both ends of the run, so you are not tracing wire behind panels to confirm which is which.
Fine-strand ultra-flex construction routes through door boots, under carpet and around tight bends without kinking or fatiguing.
