Non-JBL Stereo (standard audio system): speaker sizes, speaker harness + bracket info [upgrade info]

[deuceduzit]

Heads-Up for Anyone Upgrading a Standard Non-JBL Audio System (SR5, TRD Sport non-premium, TRD Off-Road non-premium)

Just finished upgrading the entire sound system in my SR5 (non-JBL), and I wanted to share a few tips that might save others some time and hassle.


Speaker Sizes

Dash Tweeter - 2.75 - 3.5 (I installed a 2.75 but gutting the original tweeter) / Harness - 72-8109

Front Door - 6x9 - Harness - 72-8109 / Bracket - Metra 82-8146 w/ some minor modifications using a drill. 3 out of 4 holes lined up, had to use drill to line up last hole.

Rear Door - 6.5 - Harness - 72-8109 / Bracket - Metra 82-8148 perfect fit.


Brackets / Harness

I had to reorder brackets and speaker harnesses because there wasn’t much reliable info online—I was basically guessing as I went. So if you're planning a similar upgrade, here’s what I did:

• Replaced all factory speakers
• Installed an aftermarket amp and subs

If anyone needs help or has questions about parts, wiring, or setup, feel free to reach out. Happy to share what I learned!

Radio speaker output harness (to aftermarket amp or loc) - You can find these at several sites but I bought the Amazon Red Wolf 10 pin one for $14 then used some speed wire to run to amp.

Current Audio Setup:

• Amplifier: Kicker LX1200.5 5-channel amp
  (In hindsight, the 7-channel version would’ve been a better fit.)
• Front + Dash Speakers: Kicker KSS269 component set
  (Planning to replace the dash speakers — they currently sound muddy at higher volumes.)
• Rear Door Speakers: 6.5" Kicker 51KSC6504 - 2 way speakers
• Subwoofers: Dual Kicker L7T 12" slim subs

Update
Audio System Update
• Installed 2x Kicker 47KEYLOCs to defeat the stock head unit’s nasty bass roll-off and overly aggressive factory EQ. The low-end finally breathes like it should—tight, full, and natural.
• Both units are mounted behind the radio, powered via a T-harness sourced from Amazon (seller: AutoHarnessHouse). Not sure if links are allowed here, but feel free to PM me if you want the exact one I used.

• Started 3D printing custom tweeter brackets for aftermarket installs. Dash area can comfortably accommodate up to ~4" tweeters now.
If anyone needs help with fitment or wants the STL file for the bracket, feel free to reach out—happy to share!

• Installed 2x Kicker 47KEYLOCs to eliminate the dreadful stock head unit bass roll-off and tame the factory EQ. The low-end finally breathes like it should.

Awesome post! I’m new to this… how did you wire up the LOC and remote wire?
