Crutchfield Customer Review (What's this?)
Great while it lasted. This is the first time i have ever used a breaker in car audio and the last time. Had installed for about a year, when I started noticing my amps cutting in and out at high volume. Took the old multimeter out and noticed I had a 10% voltage drop from the input to the out put of the breaker. Un hooked from the batter checked connections for corrosion, none in the wire. Cleaned the inside with contact cleaner, doubled checked amp grounds everything was still good. Installed back in still had a 10% voltage drop. Called Crutchfield and they told me to just bypass it too make sure it was that, I am not going to bypass my breaker or fuse when I have 4 ga OFC cable. went out to my local car audio store bought a new fuse holder and fuse no more voltage drop, no more random amp cutout.
Pros: simple to use
Cons: only lasted a year.
