Ok I'm having a lot of trouble. Here's the rundown of the setup in my 2019 ram with 8.4 screen and no upgraded factory speakers. Local stereo shop sold me the RF 2ohm dual voice coil subs and mono block 500 watt amp..also the PAC LP7-2 converter which...I suspect may be wrong. I installed everything and spliced into the rear left speaker..also disconnected the 4 ANC speakers wires under the driver's side seat at the factory amp as suggested. Everything powers up but even when turned up...you can barely tell the subs are beating at all. Turn the bass knob to full blast and you see the subs thump once and then nothing. Can I make this setup work or was I sold the wrong LOC and need to start over? Also my LOC is connected at the amp under the back seat as I was instructed was the easiest way to run it incase that matters
