With "Time Sync" turned on, the clock in my new JVC radio is always displaying the wrong time. I almost never use FM to listen to music - could this be the reason the time isn't being synced ? I emailed JVC and their response was to turn "Time Sync" off and set the time manually. In PA, we have...

Problem Fixed ! But, it wasn't the JVC head unit. After installing the replacement JVC, I noticed the front left door speaker had no sound. I jiggled all the jumpers I installed to bypass the Infinity Amp but still no sound. I banged on the drivers door and the sound returned. Today, I removed...

Update: The distortion returned a couple days later. I called Crutchfield and they sent me a prepaid shipping label and will refund my full purchase price. They are completely out of stock of most JVC head units due to the chip shortage but I managed to find the same exact model listed on Amazon...

Yesterday I finished the Infinity Amp Bypass project. I chose insulated solid copper wire of the correct gauge to tightly fit inside the connector to the head unit. The jumpers won't fall out or short to each other. After tweaking all the JVC's sound settings, it sounds as good or better than...

Antique electronics ? ☺ I agree that buying a used amp isn't really a good idea. If the noise doesn't return in the next few days, I will most likely make my own amp bypass jumper. Recapping the old amp would have been a breeze years ago when I stocked electrolytics but I might pop the lid on...

Update: I managed to bypass the factory Infinity Amp using 2 jumpers. I only have the left rear speaker working but there is no distortion with the engine running. Before I condemn the old amp, I will use just the one speaker for a few days to make sure the distortion does not return. Then if I...

I used the existing ground wire that was connected to the factory radio. It worked perfectly for 6 months until the engine noise started. If the noise continues after eliminating the factory Infinity Amp, I will remove the new JVC head unit and reinstall the factory radio temporarily to see if...

There is no aftermarket amplifier. My Jeep came with the upgraded Infinity Audio system which included a separate power amp under the rear seats. The video above shows someone installing the amplifier bypass jumpers to eliminate the factory Infinity Amp and utilize the head units built-in...

YouTube video showing Xscorpion Amp Bypass Jumpers Go to 32:35 of the video above

I was in contact with Metra today. They do not make an Amp Bypass Harness Kit for the 98 Jeeps. Xscorpion USA has no stock and may have closed since they no longer answer emails. I did manage to locate some in stock at Xscorpion Mexico, but they might not ship to the US. When I emailed them this...

Here is the Infinity Amp Bypass harness that I need. Can anyone locate one for sale ? - Xscorpion CHR-5622

I tried to order the Infinity Amp bypass harness from Xscorpion but they are no longer available. There is a YouTube video showing this adapter and how it just plugs in to bypass the Jeep's Infinity amp. As soon as the weather here (PA) starts to warm up, I'll probably remove the JVC and...

Thanks for the quick response. I don't see how it could be #2 or #4 since the audio is just fine with the engine not running, even for extended times. When this first started, I though maybe a bad alternator but the distortion is not a "whine" and does not change with RPMs. I suspect a bad...

I'm a 70 year old retired TV and Computer Tech. I own a mint condition 1998 Jeep Grand Cherokee and decided to treat myself to a new head unit. I ordered a JVC KD-TD71BT from Crutchfield along with a pre-made wiring harness adapter. Installation was a breeze and now I can stream Pandora music...
