Hi, my JP63’s Bluetooth bass knob stuck at “Scn”. It was working fine since 4 months. Now it is not connecting to the amplifier. Is this bass knob faulty or is fault in the amplifier?

Hi, did you ever figure out why it was not connecting?

I cannot recall the model number but another user with BT bass knob issues ended up opening the amp and "unplugging" the BT module. He said it was like a daughter board, so no soldering iron required.

I have heard about the bass knob issue and it is making me not want to buy one.

I called d4s and they told me to completely unplug it power ground and rca then plug it back in and then the bass knob started working again

They still should have the option to run a wire to it. It would prevent most people sending them in for repair

Above is a method posted by Aden Pitre, see if that solves your issue.

In this thread one of the guys had a burned out component on the BT module. Did you buy the new BT knob because the old one get stuck on Scan as well? If yes then the issue may be the BT module inside the amp.
Another question; does your amp still play but has no Bass knob control or is there zero sound?

How much watts to the amps? Make sure the watts matches with the radio you use. Match all the ohms, and the amps, since these are linear power amplifiers, they go up in increments. The power goes up constant functions. Find the correct amount is the key. If you have a 65 watts radio, then the amps you add maybe 250 watts, that is 3.8 to 4 times the power of the watts to the radio. Head unit. The linear power remains constant at 4. It will remain at 4 times the power throughout its voltage input and output readings. And not expect 2000 watts output. You probably have the wrong watts connected to your truck. Also this post is two years ago, I joined this forum under another name, 3 names, 4 names now, on June 2023. Now I'm under google sign up. But that still works too. Changed it 3 times, 4th time google took over the show. Hopefully this will be the last password I use. If not, change it like they have a menu for it. And last of all, how can you fix the amplifier? Easy. Take it to a electronic shop, they'll test it for you. Saturation mode, so shut down. They'll check to see if any mosfets are burnt out. If so, they'll change the mosfets, cut off the two leads, add a new one in the circuit. Nothing to it. Drain all the capacitors to the amp using a light bulb and neg and pos probes touching the two input leads of the circuit. OP AMP. Then test it again if it remains constant using another radio hook up and an oscillator. Sign waves in the correct amplitude. Then give it back to you. About $75 dollars repair fee for the electronics shop.​

Were you just purchase the JP bluetooth bass knob or the module separate? Have you tried to unplug the module from the amp board to see if that’s the problem? If your stuck on Bluetooth knob you can preorder LF Audio/AMP Lab, they are also teaming up with Ruthless audio amps
