Hey everyone. Recently got a single 12" enclose and a JL 12W3 for free from a friend, had it left over from his old truck. My question is, what is my best route of wiring it up? Is it cheaper/easier to change out the head unit, or is wiring it up into the OEM Bose just as good? I read about how the Bose system decreases bass as volumn is turned up, is this true? Thanks for suggestions, much appreciated.

i connected my amp to the bose sub outputs inside the center console. there are two channels going to the console sub (4 separate wires; i read somewhere its a dual voice coil??), running separate from all the other speakers wires. i can't remember the colors, but they are attached to the sidewall of the console beneath the cupholder going towards the front of the truck from beneath the storage bin (where the bose amp is).

 

 

the stereo shop that installed my line out converter hooked up to the rear L-R speakers; it sounded terrible as i could never get my adjustments right. the bass on those channels does go down as the volume goes up, but i did not have that problem using the actual sub-channels. it was a night-and-day difference; you shouldn't be disappointed.

I ran all of my wires from the outside of the cab up though the floor via the transmission shift cable gromet, and then ran them down the door channel underneath the plastic trim.

 

Now, as far as the amp hookup, I wouldnt hook it to the Bose system for various reasons, one being the bass reduction with volume increase. I used a PAC line in converter specifically for factory Bose HU running aftermarket subs and amps. It was a plug and play and plugged directly in between the factory HU and the factory wirin harness. It had 2 channels, but I only ran one since I didnt want to amplify the door chimes that come through the front left speakers. It also had gain controls on the converter itself.

 

I think I still have it if you want it. I think they cost about $35 - $40 new, but you can have this one for $20 to your door.

 

EDIT:

 

Found a picture of the converter

      Towing In Loose Gravel

      By JimCost2014 · Posted

      If what you are doing works, keep doing it:   4LO (Four-Wheel Drive Low) should only be used in extreme low-speed, high-torque situations such as deep mud, heavy snow, steep rock crawling, or extreme inclines/declines, and you must follow the correct engagement procedure to avoid drivetrain damage. Intended Use Cases Deep mud or snow where traction is extremely poor and you need maximum torque to get unstuck Trucks Only+1. Rock crawling on steep, uneven terrain forum.fullsizechevy.com+1. Extreme inclines or declines where you need to control speed and maintain traction solutionsphere.blog. Heavy towing in low-traction conditions (e.g., deep sand, ice) carclubsusa.com.

      Towing In Loose Gravel

      By rdonarski · Posted

      Hi,   I work a steep boat landing that has patchy blacktop going down the hill and soft sand/gravel at the bottom. Due to low water levels, it's not always possible reach the blacktop. I've had to help several people get out this year already and with fall coming, I'm anticipating more. I always use 4L. There was a gentleman there today with a 2500 HD (actually 2 - him and his son both have them) and they were trying to get his son's wake boat out. This gentleman swears that you should use 4H in the soft gravel. Says he was a farmer and you always use higher gear when stuck. I was wonder what your thoughts on this are? If I'm wrong, it would be good to find out before things get busy.

      Roll up bed cover experiences

      By Bill Lemmond · Posted

      Looking for feedback from users of roll up aluminum slat bed covers who have had it for more than 3 years. I prefer the aluminum slat style over supported vinyl covers due to security and the capacity to support a light load. The slight loss of bed opening when rolled up is not an issue. Presently have BAK Revolver the "industrial grade vinyl overlay" on mine is shrinking & coming loose at the rear and on both sides in addition to cracking at some of the folding joints. Truck lives outdoors in NC latitude. Can't justify the steep price to replace it with another one if that's the expected lifespan. Do you have a better alternative?

      Thanks, your last sentence is the root of my problem, outdoors truck and southern latitude = UV overload. Looking at replacing with Rough Country powder coated aluminum slat roll up model.

      Tire fitment

      By JakeD · Posted

      I’m looking at putting a lift in my 2024 gmc sierra 1500 elevation trim, has anyone had any luck with fitting a bigger tire under the rear for a spare?? Was gonna go with a 4 inch zone lift Also what wheel and tire size setup are you all running? Wondering if I can get away with keeping around the stock size a 33 inch, and just get some new wheels to have enough back spacing then I can just keep my original spare tire I have under the truck now.
