You can probably use the DIY roll on or spray on bed liner. The heat the pros use would more than likely damage the plastic

I built a down firing box with an IDQ10. Could easily do 2 of them. 2 full size 10's with some power should sound really good and more than enough for most. My 1 10" hits pretty hard and I only have 400 watts.

Where did you mount that amp?

Once you start it isn't too bad. I believe I found a DIY on YouTube that walked me through it. I used Killmat and Dynaliner https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjL_uCsyO3yAhX_mWoFHel7AVAQ-4ACegQIFhAH&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DzmlrVFsdJh8&usg=AOvVaw0O_abci8G4Ic3F1cZFdat2

I had no sound at all. Turned out to be the amp. Took 2 weeks for the dealer to replace it

I did not take pics unfortunately. Removed a pillar covers, b pillar covers, and all attachments on the top. Then lowered each corner to fit my arm in to install the sound deadener and vibration damper. Pulled it down just enough to fit my arm in.

I cheated and had a shop do mine. They installed the tweeters in the dash and the 6 3/4 in the doors. 10" down firing sub in a box I built under the back seat.

I installed Killmat in my Sierra. Nice improvement. While I was installing it I would tap on the panel to listen for a difference before and after. Worth the effort. I did not totally remove the head liner. Lot of extra work to totally take the headliner out of the truck. I lowered it and installed the sound deadener. Worth it to me.

looks good too btw

are the trim pieces pretty easy to pop off and back on?

to the best of my knowledge, you can't tune a 2019 ECU. You must replace the ECU and then have that one tuned. A regular tune isn't bad at all. I have a 2008 ZO6 with a built 454 and it's tuned. So I totally understand the tune aspect. The newer computer not being able to be tuned is what I am referring to. 2018 and older are no problem

way too expensive to tune. Replace ECM to tune for minimal gains

My installer put the tweeters in factory location in dash.

I had the Focal flax installed as well. Sound great. Along with a 10"Image Dynamics IDQ in a down firing box I built
