Sweet lug

This is a great addition to any build, awesome ground lug

By Brock on December 4, 2020 Checkmark Icon Verified purchase

Gifted this one

I gave one of these to a younger guy at work that's just getting into car audio. Aside from happy, he was also momentarily wide eyed when he saw how exactly this ground lug goes together and understanding what could be done with it.
Totally worth the price.

JL all day

Its a ground lug... what else can be said about it. It's perfect for what it does.

Love it

I recommend this product for that good n tight ground your amp needs to perform. Its big enough for more than one ground connection at a time
Pro’s: Does it’s job
Cons: none

I like the all in one solution

I like the all in one solution. It's a solid grounding bolt. It makes my install look clean if you are a little OCD like me. Once its installed you can add or remove ground wires without removing the bolt from chassis!

JL Audio XB-MGLU

I used this grounding lug to replace the inferior factory battery grounding point. This grounding lug is very high quality. I wouldn’t expect anything less from JL Audio.

Quality piece

I built this to go along with the rest of my sq build. (Actually bought the last two in stock). Perfect for one or multiple amps, it's over built and gives room for expanding if installed in a good central location.
Probably would have bought more if there had been more in stock. Will buy more later for under the hood grounds.
