These TRUCONNEX TCRTFT-4 4-gauge ring and fork terminals provide an easy connection to your vehicle's amplifier and feature gold-plated steel construction to ensure a durable design.
I have a 4 gauge wire hooking up to my amplifier and I wasn't sure if this would fit or not but it did. I had to twist the heck out of the wires to make them as tight as I could get them and spread open the clamp and it was a fight but it fit well enough. No problems at all after hooking them up, I bought them to help organize my amp wires because the positive cable was all over the place and pretty scary. They do their job and I still have extra because it comes with more than I needed.
Upgrade your car audio system with these Alpine Type-S SPS-510 2-way coaxial car speakers, which handle up to 170W peak power and feature 5-1/4" poly-mica woofer cones and 3/4" silk-dome tweeters for a wide range of frequencies.
I bought these because I bought a pair of amazing alpine rear speakers and it is hard to find a 5.25 inch speaker but they do not quite meet what I had expected. They have amazing treble but I'm disappointed in the bass. These are on the cheap side of the scale and I would recommend that you save up an extra pay check or two to get better quality speakers.
