Review on Enhanced Stinger SPD511 PRO Series Power/Ground Distribution T-Block: Triple 4 Gauge Inputs for Optimal Performance by Jason Sergeantson

I have ordered 4 of these. 2 I'm using now, 2 are for a future update. They (positive and negative) are between my main power distribution center and split to go upstream to the appropriate amplifier/capacitor for their circuit. They accepted my 4 gauge wire with no problem and tightened it neatly. I would buy them again if I had to as they worked great and kept my rig clean.
