Kxable RCA Y-Adapter Splitter Cable 15 Feet, 1 RCA Male to 2 RCA Male Stereo Audio Subwoofer Cable, Bi-Directional, for Home Theater, Hi-Fi System, Amplifier, Speaker, 24K Gold Plated, OD:5.0MM

👍 Forgot to mention theres 2 types of Y cables, theres a male or female end going into the green Subwoofer out. Make sure you get the right one. Of course you'll have to look at your green sub wire plug to see if its male or female. Here's a couple as examples https://a.co/d/04pPFv65 https://a.co/d/0btPZdqk This is pretty cool, it's a built in RCA Y Cable so if you buy this you won't need RCA cables. It's 15ft long so long enough from your headunit to amp in trunk. https://a.co/d/0fztSm51 By the way, always fish your RCAs on the opposite side of your amps power cable. If you have power cable running down the drivers side from battery to amp, then fish your RCAs down the passenger side from headunit to amp. Good luck let me know if you need anything else
