Our take on the T-Spec Pos/Neg 4-Gauge Battery Terminal

by Buck Pomerantz

Compact and heavy-duty

T-Spec designed this Pos/Neg battery terminal to be extremely compact, so you can make the battery connection for a 4-gauge power cable in almost any vehicle. The other outputs accommodate your vehicle's OEM factory wiring — and there's even room for upgrading that. This heavy-duty black nickel-plated brass terminal can be used on either positive or negative battery posts. Requires Allen head wrenches for installation. Warranty: 1 year.

T-Spec terminal

Written By 122Viper, Lowell, IN on Saturday, March 08, 2014
Crutchfield Customer Review (What's this?)
I had a bad battery and corrosion ate away the wiring so I needed a new connector. This is a nice product, but it did not fit my battery terminal. It was waaaay to tight. There is a sleeve in the clamp, and the fit was so tight it would not seat so I ended up using a rubber mallet to pound it down. Needless to say, the clamp screw was useless since it was now too small. Not like it's not on there tight though, but if I need it off, it'll have to be pried and I'll have to get a new connector. The allen wrench screws seemed a strange size or stripped. I have multiple sizes, and one fit two perfectly, one a bit loose, and the other screw the wrench just turned and the next size up was too large. Weird. I managed to get all the wiring in and tightened to the point where hopefully nothing will pop out, especially the one wire on the bottom. If that comes out, I'll have to pry this thing off to get to it and since it's a car wire, I could have a major issue if it comes out. Fine for now, but I'll be looking to replace it. Given my experience, I would not recommend this.
Decent construction
Bad fitment, screws not all sized properly.

Battery Adapter

Crutchfield Customer Review (What's this?)
Nice and clean looking adapter to get power to my amplifier. Wish it had three 8-guage openings instead of two.
Easy installation and looks good.
