Get the right wire for your amp

The PA8BX wiring kit from EFX will supply your car amplifier with the wiring necessary for receiving its signal and powering up. The 8-gauge power and ground cables ensure that your amp gets all the power it needs to play music at its full potential. The ground cable features EFX's Ultimate Ground Terminal, which attaches to your vehicle's chassis by way of 2 self-tapping screws (included) to make sure you get a tight physical and electrically secure ground connection.

This wiring kit works with amplifiers with between about 250 to 450 watts RMS of total output power. Please check your amplifier's installation instructions to confirm the proper size wire to use. The kit includes a stereo RCA patch cable, remote turn-on lead, in-line fuseholder, fuse, and an assortment of connectors and hardware to help with your amp's installation.

This wiring kit does not include speaker wires. You will need to purchase those separately, in order to complete your amplifier installation. This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps.

Twisted pair construction gives you maximum noise rejection and better sound quality. The RCA plugs have a micro barrel design and integrated strain relief.

Can't beat the price

Crutchfield Customer Review (What's this?)

Well, even at retail price this wiring kit is more than adequate. It was plenty of wire, all the needed connectors, grommets , ties and a good fuse holder. The ground wire is just under 2 feet, which can be limited, however most amplifier companies recommend a ground as short as possible. I would order again if I ever expand my system.

Pros: One kit is all you need.

Cons: ground wire could be longer....

Looks like the difference is also the Fosgate kit has 3' longer rca versus the efx. and the ground wire is also 1' longer at 3' instead of 2'. I used the efx and mounted a sub in the trunk of a crown vic. I would have liked the extra length on those rcas and the ground also, but it was enough to get it done but if my box slide around my trunk from one side to the other, I would tear wire loose because there isn't enough slack. With the efx, I did have to pull the rca cable fairly tight as I routed it along the door trim so that I had the slack I wanted at the trunk. I said to myself that "they could've made this just a little longer." A crown vic has some decent distance from head unit to trunk. Anything longer and the extra 3' might be necessary. [ James  Nov 14, 2014 ]
This kit is a good deal, and includes some well thought out cabling. I really wouldn't waste too much money on brand-name wiring, since a connection is still a connection. All that matters is 1.) how much copper/aluminum is in the wire, and 2.) how well shielded and insulated that cable is. For expensive, name-brand cabling, you might be getter a little more metal for the advertised gauge, but for the extra you pay it's not really worth the investment. When we talk about power and ground cables, it's just insulation, not shielding, so if the gauge is up to par, buy the cheapest wires. When it comes to signal cabling, such as the RCAs in this kit, the shielding comes into play. And from what I can tell, the shielding is just fine. Don't waste your money on paying for a brand name, as this kit works just fine. [ Cathrine  Nov 13, 2014 ]
Oxygen free cable is oxygen free cable, no matter whose name is on it. My only comment is how big is your amp? I used this kit to go from the power dist. block to the amp. I ran O gauge from the battery to the pd block. [ FLIP E  Nov 13, 2014 ]
This is a nice kit just paying for the name [ ZACHARY  Nov 13, 2014 ]
This one is better as it comes with more and a bigger gauge kit. Better if future plans on multi amps [ DERRICK  Nov 13, 2014 ]
Quality of wiring always makes a difference. But quality amps and head units always matters most. I have this kit for my Mustang, all Alpine equipment and it is beautiful sound. [ EDWARD  Nov 13, 2014 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Greg  Nov 13, 2014 ]  Staff
