Review on Audiopipe 4 Gauge Wire Reducer: Maximize Power Efficiency with this Effective Product by Robert Tirona

These adapters have made my installation so much easier and cleaner. The 4 gauge cable fitted perfectly and the set screw secured it with no problem and then slid right into the amp's power and ground jacks with no problem. I will note that if your power supply and ground on the amp are close together look into the bias reducer. They are large where your cable enters and may touch once installed. Mine were spaced apart so that wasn't a problem, but the amps I've had in the past required offset to avoid contact. My only complaint was that one of my packages didn't have a set screw so I couldn't use one of the ends as intended on my terminal block, but that wasn't a big deal since I just had the wire plugged directly into the block. and closed it as usual. Otherwise it was great. Note: For those who don't care about audio, you can use (for example) 4-gauge wire for an amp that only accepts 8-gauge. I hope this helps anyone looking to try their own setup for the first time.
