Amplifier Wire Terminals

Hi all, I was wondering are there any terminals that can be used for these types of amps? or are you just supposed to squeeze the wire in there? thanks

I'm more concerned about the power and ground wires

Thanks

Strip the insulation from the end of the wire and tin it with solder.
Crank the screws down, then check torque after a few weeks.

I've never seen them for cables that large.
The power interface module for my traffic signal battery backups have a terminal crimped onto the #10 wires.
It's like a butt-splice crimp connector, but the non-insulated part is more of a pin.

But on a large amplifier feed, it's just introducing one more unsoldered failure point.

Looks like they are available for some pretty large conductors, but the secondary problem is that you can't use a basic hardware store crimp tool on anything much larger than #8 or #10.
The crimp tool for #4 looks like a pair of bolt cutters (and I have seen some DIY tools made from bolt cutters).

i guess if it's not typically done, then there is no need for me to do it, I'll most likely go the solder route, thanks for your help!

to echo what Rich said, you really don't need a pin connector for this type of application. i've installed many amps that use the same connections and have had zero issues cranking down the screw on bare wire. also when you screw onto bare wire it will deform and become "flat" giving the wire more surface area contact with the amp terminal. more contact surface area equates to more current transfer. pins are pretty hard metal and will typically stay a rigid barrel.

my only word of caution is not go to town tightening the screw onto bare wire. over tightening the screw can compress wire strands to the point that they will break. that's where it's a good idea to solder.

GL!

They do sell terminals that will "crimp" onto a 4ga wire. check out Stinger Electronics. They do alot of car audio accessories

cool thanks, I actually tried it last night, and it's a really solid connection

yea the amp kit actually came with some, but they were just the fork or ring kind, I was just wondering if they made any specifically for that screw down terminal

or is this it?

damn that's almost as much as my amp wiring kit

They sell terminals that will crimp onto 0000.

But you are not going to be able to PROPERLY crimp anything larger than 8-10ga using typical hardware store/auto parts store tools.
6ga and heavier require a heavier tool:

For wire in the #2-#6 range, you can get by with a pair of bolt cutters with the cutting edges ground flat and a hole drilled through the edges of the blades to shape the lug.

That one is the same kind of compression terminal that you have on the amp, with an adapter to allow it to fit under a 5/16 terminal strip
