Update: I replaced the door speakers with Infinity Kappas and the audio no longer cuts off at high volume. I guess it wasn't really a power supply issue I was having, the stock speakers just could not handle the power coming from the Clarion amp.

What would be the best place to spice in a Line Output Converter for a subwoofer amp, at the Clarion amp inputs or at the Clarion amp outputs?

Inputs because it is lower wattage

Can you please elaborate, I'm new to this?

You want to use a signal before it is amplified therefore tap the wires before the amp for a cleaner signal.

I see, thank you.

I put this harness together with a alpine ktp-445u last week. Everything worked great and I have a kicker hideaway tied in before the amp. Driving home from work yesterday it cut out- no difference from any source, and now there is just a constant 'thumping' from the right rear speaker. I can't adjust volume or fade. I can't turn the thumping off. Its constant whether the truck is running or not. It even stays on after I take the key out for a few minutes, after I open the door. I pulled the radio fuse which makes it turn off.

All the wiring was soldered- yellow lead from harness going to red lead of the amp. Ground to ground. I left the blue turn on wires unconnected and it worked fine without it. I cut the bluetooth fuse off and just used the amp fuse.

I'm going to go dig in and pull the harness today. Any ideas what might be going on?

EDIt: Pulled the harness and hooked everything back up stock. Works fine again. Truck is a 2014 FX4 with the 8" MFT.

Sounds like the Alpine amp is blown. Did you ever figure it out?

After the amp blew I pulled the parrot harness out. I figured with my limited knowledge of audiosystems and unwillingness to cut into any factory wires I'm better off leaving it stock.

I have been doing performance audio for years. Personally I think running the amplified power from the head unit into these small amplifiers is likely the reason people are experiencing amplifier failure. I recommend using a good quality line out converter from AudioControl to bring the signal down. Even if they say it is ok to run power into these small amps there is no way it can be good for them in the long run.
