JL Audio 4 AWG Amp Kit

Amplifier installation kits can save you time & money when installing an amplifier in your vehicle. Instead of purchasing everything you need separately like power/ground cables, remote turn-on cable, fuse blocks, fuses, and more, you can get an amp kit that already has the cables & accessories in one package. Amplifier wiring kits come in various gauge configurations depending on the wattage of your sound system and include all the necessary components you need to successfully install an amplifier.

This JL Audio 4 AWG Amplifier Power Connection Kit includes all the necessary hardware and wire to power one amplifier and is designed specifically for car audio systems up to 800 watts. The included premium power/ground cable is made from 100% silver-tinned oxygen-free copper and is true-to-gauge for ultimate power transfer. This XD-PCS4-1B power amp kit includes 19-feet of 4 AWG frosted blue power cable, 3-feet of 4 AWG black ground cable, 20-feet of 18 AWG blue remote turn-on wire, Maxi Fuse holder, 80 Amp Maxi fuse and more.

Great Product, Didn't Include Everything I Wanted

I'll start off with the good and say this is very high quality product. There was plenty of wiring to reach the subs in the back of my Yukon XL. However, the wiring kit did not include an RCA cable or spade terminals (I believe that's what they're called). I cannot dock the product any starts because of my lack of reading, but I really feel like for as much as I paid for this product it should include everything you need to install an amp. I'm happy with the product, but I wouldn't buy it again just because it didn't include the RCA cable.

well worth it

this is some top notch kit I have it ran in my pt cruiser about a year half ago from my local installer and I recommend it to all my friends and anyone who asks but buy it here because a installer will get double the price for this kit (pros) true gauge wire delivers the power my system needs to pound (cons) none I had it for over a year now
