Get the right wire for your amp
The PA4BX wiring kit from EFX will supply your car amplifier with the wiring necessary for receiving its signal and powering up. The 4-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 3 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 450 to 1100 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.

Really nice kit. Not a big fan of the style of the fuse holder at first, but I figured it out and it works well. Wire is very easy to work with and high quality.
