Painless Performance Products. Established in 1990, Painless Performance Products has been providing the performance market with painless solutions to automotive wiring

This kit is made to insert between a power cable on your car, since I am upgrading my wire to a 0AWG you will see me installing a new wire.

n "SKY HIGH CAR AUDIO 1/0 GAUGE OFC", the "OFC" stands for:

Oxygen-Free Copper

This means the wire is made from high-purity copper with very low oxygen content (typically less than 0.001%). It’s considered higher quality than CCA (Copper-Clad Aluminum), which is a cheaper alternative.

Why OFC is better:

Lower resistance – better conductivity
Less heat buildup
More durable and flexible
Higher power handling
resistant to corrosion.

I upgraded to the switch

The Painless Performance kit includes everything you need. However, since I'm adding an aftermarket switch with a light, I had to create an additional power circuit to illuminate the blue LED, which is not included in the Painless Performance kit. This modification enhances the setup.
