[QUOTE="WIN27, post: 8709576, member: 677344"] I’ve been troubleshooting an issue in my truck for a while now. Here’s where I’m at. 2014 Toyota Tundra crewmax. Stock speakers and head unit. Aftermarket amp and two subwoofers behind the backseats. I had the amp installed when I bought the truck in 2014. A year or so after I wasn’t getting much power. Turned out to be a bad ground. Everything was fine after running a new ground until around the beginning of the year. The bass just wasn’t there like it used to be. At low volume I couldn’t hear it, or sometimes it will pop and distort (only in the subwoofer). I tried connecting my phone directly to the amp. I still got the distortion. So I ruled out LOC or wiring issue from head unit. I then tried an old amp I had lying around. It sounded much better for a couple weeks. Then it started doing similar. Last night I took another subwoofer down to test if it was the subwoofers. Different wires to different subwoofers. Same thing. At high volume they sound great. At low levels there’s distortion, they pop. The subs in there are JL 8”W3 from 2014. The first amp was probably 15 years old, the second was about 20.
