3rd Gen non JBL sound system Upgrade Info

I was actually going to try a direct run over the seats to test that as well on Thursday, good call. I used a dedicated turn on, that GTO stuff has screwed me and some other guys over before. Also going to try a JL signal processor my friend has at the shop. Thanks for the help.

 

Sorry to interrupt the current discussion but I wanted to update that we have these long versions of the factory speaker adapter available for the non-JBL trucks. It's essentially the 10-pin connector (with 8 wires) that is an extension for adding an inline amp between the OEM system and your speakers.

It's 26 feet long so that leaves you 13 feet of length in each direction.

 

Almost completely done. Waiting on my 3rd sub to show up so I can wire it in and screw it down. The stock wiring upfront worked with the AHH harness wired together.

I went with the fox acoustics box and Hertz Millie Pro MS250 s4 subs. 3 of them wired down to 1.33ohm with a sundown SIA 2500D amp. 3 of these subs ported is almost perfect in this 2.4 cubic foot box. If I add a 4th it will only work sealed.

Took out the rear trim compartments and the rear storage tub to get this two piece box installed. Really good craftsmanship on the box and I used weather stripping between the two pieces for an air tight seal when bolted together.
It's sounding really good right now but the 3rd sub should wake it up after I adjust the gain again.

It's been a hell of a project over the past month only working through it on the weekends and needing it buttoned up before Monday so the kids can ride in their car seats.

I have some deadening left to complete on the rear passenger door only. I will order a mic and start in on some RTA soon.

 

Finally got around to adding tweeters to the a-pillars a few months ago. Became motivated so i decided to upgrade further by moving to D.6.1200 amp, Mille Pro drivers (front-stage), Knuconcepts wiring, and additional Soundskins. Purchased a Mic and used REW to EQ. I managed to get everything tuned very close to my desired house curves. Red = Midrange and Tweeters. Yellow = Midbass. Blue = Subwoofer. And Green is my desired House Curve for each. Pretty spot on; the sub needs to be boosted more but overall things are pretty close. b/t/w Still have the Kenwoods in the rear stage, tuned them too and they fill rear stage well. Did all the installation work myself this time around and learned a lot (and still learning), both about my truck and custom audio in general. Thanks everyone for this thread and all the info.

 

Looks good! I’ll be swapping out my tan JBL A-pillars for black this weekend so just lmk if you decide you want to go for something more discrete for those tweeters

 

Thank you, and thanks for the offer! Appreciated. May reach out. thx again
