It came up with P0562: System Voltage Low, P1DB1: Transmission Control Module System Voltage Excessively Low, and U1267: No Valid Data from ESM on CAN.

Well drat. They aren't going away on their own. I haven't messed with any of it in a week, and have driven it ~20 times, ~50 miles.

I went by an Advanced Auto just now and had them run a battery tester. It came back good, but one surprising thing was that for a 730 CCA rated battery it was coming in around 940 CCA on his reader. 12.67V. I also snapped some pics of all the warnings on startup: Service Antilock Brake System...

I'm not certain if it was "full full" charged, but after an initial jump to get it rolling, I hooked my battery charger up to it for about 4 hours, and then got in it to run errands for about an hour. I've driven it for about a week since then without any electrical issues, other than these...

TLDR: I drained my battery. Lots of dash warnings/codes. Recharged battery. Is there some way to clear these codes/dash warnings that I'm not familiar with? Hey all. I was messing around with my truck's audio system for several hours and ran the battery down to where I was unable to start the...

I tracked the money in a spreadsheet. Other than that final number, I'm super happy with it!

It's tough to give you a good rubric to get there. Unfortunately, the factory amplifier creates quite a bottleneck on any other improvements to get to an 80%+ level due to the factory processing. Going around the factory amp is going to hit the pocketbook pretty hard. If you wanted to skip the...

After finishing up with the frontstage, I put them all together into Dirac 1 (left front) and Diract 2 (right front) and added in my rear midbasses and rear headliner speakers as independent channels. The headliners had to be independent because I was feeding their output as a differential R-L...

I spent about 5-6 hours yesterday tuning things with the C-DSP processor. My approach, sharing with others for any potential feedback or benefit to future DIYers, was to tune the frontstage 3-way system, with the subs, using Dirac Live's outputs to manually set things in the DSP as close as I...

Here's some finished pictures from the third amp install, showing how I used the factory seat bracket bolt locations to help hold it stable. That lump to the back left of the amp is the eTorque battery cabling under the carpet. Also a few other shots of the finished hardware installation. From...

The MLV barrier I installed runs between the factory widgets/dodads and my amplifier rack, so in a way it likely offers some protection to the OEM equipment that is recessed in the lower area. The amplifiers sit outboard of the main upper vertical plane of the truck's structure, but if there...

I've finished getting the rear speakers installed with the new Focal 4 channel amplifier. I also have a new phone, so here's a few pictures of that process. It was a vast improvement by "going around" the factory amplilfier, mainly due to the crossovers and getting DSP on the rears. The rear...

8/06/23 Update: I ran into a conceptual problem with my plan to reuse the factory wiring for the rear doors and the headliner speakers, so I thought I'd share, and I haven't found a product that solves this problem easily for me. The PAC APH-CH42 that is required to make the connections behind...

07/30/23 Update: My GS690s and GS25s came in, and I've finished installing them in the factory rear door and headliner locations and putting everything back together. I'm still waiting on the amplifier to drive them, but they're receiving an amplified signal from the factory HK amp for now. The...

Impressions/Summary I've finished with the main hardware, deadening, etc. and have been driving the truck around for a couple of weeks now. I have some future plans, but I’ve got what most people would considered a finished install at this point. I listen to a lot of different music, and want...

Questions So this leads to my question for anyone that's using a PAC for their aftermarket system. Are the system audio signals (non-music) like bluetooth calling, etc. gone if you've gotten rid of the factory center channel, or interrupted it's factory signal flow through the factory amp, etc...

Future Plans I'm also game-planning another 4 channel amplifier for the rear door and headliner speaker positions. With every build I’ve done, I tend to go “one step further” than I have before, and for this build I want to play with two new concepts to me. I want to try adding additional...

Install Stuff Amp Rack – I’ve made several for my previous pickups, so even though there are premade solutions out there now (how cool is that?) I went ahead and made my own out of ½” MDF due to space constraints/concerns due to the amount of equipment. One trick I’ve used in the past is to...

Soundsulate 1 lb Mass Loaded Vinyl (MLV) – I bought 100 sq ft (4’ x 25’ roll). I wasted a lot to make sure I had a continuous sheet for each application location, and I still have some leftover. I used some of the larger scraps to make toolbox drawer liners. Of all of the products involved in...
