Installed my first system today. Went with a Blaupunkt combination 10" sub and amp. Fits perfectly under the rear crew cab seat. Wired the speakers directly to the stock head unit front L\R speakers, Used fuse 30 for remote on. Everything was a breeze except trying to get through the wiring boot. I cut a slit in the nipple on top and just spent about 10 minutes with a wire Hanger gently probing until that sucker went on through. Very happy with it, good bass inside without being a 48yo teenager shaking the cars next to me.

2014-2018 silverado amp subwoofer install

I’m gonna do a quick write up on my install. I am by no means a pro, this is what I did and I’m sharing my  experience.

Supplies:
Lockit posi-taps 22-20g 6pack

Posi-lock Connectors 14-16g 8 pack

Blaupunkt  GTHS131 10" subwoofer with 200 watt amp combo
25" speaker wire

Boss KIT2 8g Amp kit (be very careful, the power wire is literally 6" over for a crew cab from battery to the rear seat.) It does not have enough speaker wire to run 2 pair from the head unit to the rear seat.

Zip ties
 

My amp has hi-level inputs so I didn’t need a Low level converter 

I have always used the front door speakers for amp installs. They are full range while many times the rears, tweeters, etc are only given lows, mids or highs.
I tap into the fuse panel rather than splicing the antenna on.
Remove kick plates on both sides of the front of the truck, remove sill plates front\rear.

 
*Turn off radio, Disconnect negative, than positive battery cables. Remove battery cap

Speaker wires:

 

pull the trim piece (very carefully) from around head unit, there are plugs on the bottom that just press and remove.

remove the lower glove compartment 

remove head unit, 4 7mm bolts and gently pry out.

remove 3 plugs holding head unit to screen

-The upper large green plug is what we are working with..pull back the black tape at least 6". your gonna use the Blue\Brown-bluefor the Left speaker and Yellow\yellow-blackfor the right. I don’t believe +\- matter with an amp. Run 2 speaker wires (I had 2 different color speaker wires to run so it made remembering L\R easy) up from the glove compartment area, through the framing around the head unit and connect with posi-taps to the wiring. 
-Run both speaker wires under glove compartment and secure under R front kick plate. Carefully pry covers off the wiring channels and run wires,down Passengers side, gently pushing under the B pillar trim. Run under the rear plastic trim and pull wires behind rear seat to the amp. If you need to use a in-line converter this would be a good place to do  it, lots of room. 

 

Power wire, remote on:

Tie 8g wire near battery making sure to leave 8-10" extra

run along back of engine compartment securing to wiring bundle that already exists with zip ties.

Cut a hole in the nipple on top of the rubber boot to the upper right of the steering linkage. Take a wire hanger, dull the poking end. Gently start probing your way through the interior wiring. It will take time but if you keep gently pushing and moving it around you will eventually break on through to the other side behind the large plastic box in the  footwell. I tape a left over speaker wire to the hanger and slowly fish it through. Then I join the 8g and speaker together, easier for me than trying to force the 8g, hanger and wad of tape through a very small hole.

Secure 8g under footwell behind kick plate
I used a fuse tap for remote on *fuse 30 and 32 come on with key*. Secure wire near fuse panel and in footwell.

Carefully pry covers off wiring channels and run wires down drivers side, gently pushing under the B post pillar. Gently push under under the rear trim and pull up behind seats.
 

remove 18mm nut under rear seat behind the jack tools, sand paint around the bolt and use this for the ground. 
Hook up your power, remote on and ground.

Hook up 4 speaker wires to amp.

Hook up the remote control if you want it, I didn’t 

I have the under seat storage from Doha and my system fit perfectly in the center.

Install fuse In fuse panel, making sure wiring is secure

Cut 8-10" of 8g at the battery. Install in-line fuse and grommet. I hooked into the 2nd from the front positive post on the side. There are already wires hooked up to this post. Secure the fuse, I mounted to the plastic at the back of engine compartment 

Connect + then - cables.

Check amp and make sure it is NOT on. 
Turn the key to acc, the amp should now have power. 
Start putting your dash back together. At this point you should be able to check out your system. Put the truck back together, make sure no wires are pinched or exposed.
Finally I used some JB Weld liquid around the cut in the rubber boot.
Hopefully all went well and you are now the coolest dad in the Lowe’s parking lot!

      I wonder how much carbon is on all those high mileage valves?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
