Review on InstallGear 100A 4/8 AWG AGU Fuse Holder Distribution Block - 4 Gauge In To (2) 8 Gauge Out For Auto, RV, Motorcycle & Boat by Jack Robi

Does what it's supposed to do, but beware! A couple of the screws on the underside that hold the fuse holder to the metal block where the wires go were loose on mine. Didn't notice until installing it and a day later, one of the amps is not turning on and you can smell / hear the sparking from this distribution block because of the loose connections. All in all, a decent unit, but I would strongly recommend checking the screws that hold this thing together and using a thread locker to keep them in place.
