Push Terminals are chrome plated, and are marked with a red and black colors to designate the positive and negative terminals. They offer the simplest installation and provide a nice secure connection.
Standard Push Terminals are made to accept a single 8ga wire and use a tab soldered directly to the push pin, to which the leadwires from the voice coil are soldered.
LARGE Push Terminals are made to accept a single 4ga or dual 8ga wires and use a heavy duty, extra-thick tab bolted to the push pin, to which the leadwires from the voice coil are soldered.
Direct Connect wiring offers the very best connection directly from your amplifiers output wiring to the voice coil of your subwoofer. Our direct connect wiring is securely attached to our interwoven braided lead wire via high temperature solder, then covered with heavy duty heat shrink. You can make your connection to the wiring via the twist and tape method, large wire nuts, crimp connectors, or solder.

This is the best sub I have ever owned. I have thrown everything I possibly can at it and it still works perfectly. This sub has great sound quality no matter how big of a box you have it in. I’ve personally had it in 3 different boxes and the sound quality has been amazing in all of them. I would highly recommend this sub to anyone

Best sub I’ve owned so far! I have 1 upgraded and even running just a hifonics amp right now. it still hits harder than both of my 2 old c2 audio 15s. I can’t wait until I get a better amp to hear the subs full power!

I have one of these in a box in the back seat of my pickup truck and it’s crazy. I have a hifonics 4k brutus running it at 1 ohm and this sub has not even flinched at it. Thanks PSI for the hook up on the amazing sub and great customer service

I have clipped the hell out of these, ran them with 7 cuft per sub, ran them below tuning and more recently send them over 3000w rms to these for years and they’re still going strong.
