JL Audio JX 500/1 or Different?

[legaspi89 10+ year member]

My JL JX Audio 500/1 recently went out on me. It is paired with a Single 12 inch JL Audio 12w3v3 (2 ohms). Should I replace with the same amp or go with an Alpine Amp for better performance? If a 1 channel Alpine Amp can give me better performance out of my sub which one should I purchase? Thanks...

What happened to the JX500/1?

I'm getting a rumbling sound on my subwoofer everytime I skip tracks on CD or Ipod. I checked the rca cables and they all seem good. Added a little noise filter device and it got rid of the problem however it lowered the output on my sub, so I took that out. I had a technician that tried to run an external set of RCA cables and Bypass the Bass knob I use but to no avail. The rumbling sound still occured. Good chance It might the Amp.

What's the amp's ground look like? Something the technician should have checked, or at least asked.

Not sure if he checked. The amp's ground is on the metal part of the chassis, sanded down pretty evenly and connected pretty solid.

Ok so how about the amp's wiring? is it the right gauge that it will accept?

I believe so, but I will double check.

Did you have the same audio source when the external set of RCA cables was connected?

Yea, it was on "CD" on the head unit.

Your troubleshooting is not compete. Try plugging in your phone directly to the amplifier and play a video or music file.
