You have stray RF that's getting into the keying circuit on the amp. Double check all connections and coaxes and make sure everything is tight, and there's nothing pinched, cut, or scraped. Make sure all your devices are properly grounded as well. It'd probably help too if you ran just one of the 102's, instead of both. Hope this helps!

yeah loose the 2nd 102... co-phasing is a waste of time/money imho
try a new patch cable... it might help

I believe the best thing you can do is to make sure the shielding on your coax has a proper bonding to the body/chassis of the vehicle and not depending on the coax's connection to ground through the radio's mounting/power connections to ground and if common mode currents are present this will show up in all devices connected to the feed line.
Best place to bond your coax is very near where it connects at the antennas' mount and if you have extra coax going to the antenna that it is coiled up and thus creating a choke to stave off cmc's/

noted on the 102s i really like running them both one on the front bumper one on the middle of the bed i was wondering if im reflecting a lot of rf back on the cable bout to check it now
Off hand should be one of the below or a combination of.
1) Your antenna setup needs help. Are you using a proper 75 ohm co-phase harness?
2) An amp that does not want to un-key needs better ground.
3) Double check your jumper, use at least a 6 foot jumper.
4) That janky dual 102's really bugs me. Dump it for A pedator 10k or single 102"
You might bench test the amp on a base to rule it out as a cause. Then you know the antenna and grounds need attention.

Yes thats what HD stands for. The radio is your driver. Thats all that amp needs.
installed grounding straps on the antennas works great now adjusted how i had the amp plugged in now close to 200 amps thanks guys
