Always a win with Posi
Crutchfield Customer Review (What's this?)
Posi connectors really are awesome. Major time saver. If you're not sure exactly what you're in for on an install, I'd always throw some of these in the cart. They just come in handy.
Pros: Work really well. Hard to create a short
Cons: Wish they still made the butt splice version with wire entry on opposite ends. That one was my favorite.
