Speaker noise after AMP install

[Mdoiron]

I have a 2018 SX210.

Installed a PYLE Marine AMP on my stock radio. I hear regular interference in all speakers when the blower is on but I also have a very loud clicking noise coming out of (only 1) speaker to a point I needed to disconnect it. The sound is a loud clicking/thumping noise that's bouncing the cone part of the speaker. I'm at a loss for trying to fix it as it's only 1 of 4 speakers. Any ideas what the cause could be? Also, is interference with blower on an easy fix?

I would start by checking the ground wires to make sure everything is good and tight. PYLE equipment can be a gamble. Their components and quality control seem to make for some quirky products. It will help if you share more detail on how you are powering the amp.

Powered with 8 gauge wire direct from the battery with a fuse between. The manual only called for 12 gauge.

I would start troubleshooting by cutting the stock head unit ground and connecting it to the amp ground, assuming you ran new + and - wire from the battery.

Where is the amp located? Your rcas may be picking up interference on route to the amp. I suspect that's the clicking noise (and why it's so loud - it is being amplified). The background noise is likely a ground loop between the amp and head unit.

Did you use a quality RCA cable? I had the exact problem and it was a crappy long RCA cable that I had coiled behind the helm. I’m sure that didn’t help because it creates a current transformer. I went to Best Buy and spent $20 each on 6ft long cables and that solved the problem.

Amp is located behind my head unit.

Is there a way to test RCA cables? Thought quality was decent but never know. Bought a kit on Amazon.

Yeah. Unplug all of them and then try each one on the channel that is popping. If they still do it, it's a bad amp channel. If it's just one cable i would try swapping a different cable on that same channel from the head unit to rule out a head unit issue. Using the same power and ground as the amp is always a good idea.
