Review on Stinger SPT521 Gauge Reducer Input by Brad Blake

Excellent product. Arrived quickly and quite heavy for how small they are. Comes with 2 red and black stripes as required (NOTE: I BUY 2 OTHERWISE IT ONLY COMES WITH ONE RED AND ONE BLACK) Even after reading the specs and making sure I'm buying the right product I've always had still small problems. . My Rockford Fosgate R1200-D has 4Gauge entry points for B and Neg but still won't fit in. I had to trim a bit to make sure they fit properly and snugly. In general, when it comes to speed, price, and quality, you can't go wrong.
