    • Solid
Been in Car Audio for nearly 30 years these are really well made out of all the brands I've used. It also one of the best I've seen made by Rockford. Very clean looking.

    • Great pair of connectors!
They work well, and make running multiple cables to your terminals trivial. When I'm working on the electrical components on my truck, I like to disconnect the negative cable from the terminal and flip the cover over so I don't worry about the connector coming back into contact with the terminal. I just wish I didn't need the adapter for the negative terminal, because I have to be careful not to drop it every time it's disconnected. ... show more

    • These are great, but they don't fit the large battery posts in my diesel truck.
Great quality parts here. Very solid, only that's also the only issue I had. It was TOO solid. I couldn't bend them open even a little bit. These will likely fit your car perfectly however, they do not fit on the posts on my TRUCK battery. Other than that, they fit 1G, 4G, and 8G perfectly.

    • Very strong pieces with no worries from tightening.
Really like these a lot better than the Kickers they replaced. Strong clamps with no worries about over tightening the battery mount bolts or the wire mounting set screws. There’s plenty of room for my added circuits for the 4gauge stereo power and grounds as well as for the added on electric Flex a Lite fan, HID headlights and the MSD ignition. Great product and it matches all my Rockford Fosgate gear. ... show more

    • Nice, robust, and clean appearance.
These are nice. Would rather have three 1\0 than two 1\0 and two 4 gauge. The cover seems more durable than a thought it would be. I got these to relocate the auxiliary battery in my truck. I liked them so much that I ordered a second set for my negative terminals.

    • Sturdy and feel well built
Sturdy and feel well built. Bought these to put on a Kinetic HC 2000 battery AFTER I had purchased the KnuKonceptz 0 gauge battery terminal. The KnuKonceptz would not fit on the positive post. These fit both the positive and negative. Very well built. Would buy again but don't think I'll need to. Nice job Rockford. ... show more

    • Wrong One
With my 4 gauge Rockford Fosgate amplifier installation kit, I got a very nice version of this which had a 100 amp fuse integrated right into the unit. The fuse was too large for my 50 watt x 4, 4 ohm setup. I installed a 50 amp fuse and it's perfect. Now I would like a 3 output version if I can get it, so I can plug the other 3 small power wires into their own seperate channels, but all I am finding are non-fused versions! I know Rockford Fosgate makes a fused one with 2 outputs as it came with the kit. Lines need to be fused as close as possible to the battery, so avoid these non-fused units and use the difficult to find fused units. ... show more

    • Exactly what it was marketed as !
This connector is exactly what it said it was. All of the wires ran very neatly and work and acted very well to the battery thank you for a good product !
