Ive been reading alot and Im still not getting whats the best way to put a small amp in for replacing the factory speakers with the factory head unit. my front drivers side speakers are both shot. So while im doing, I want to do components in the front and regular speakers in the rear powered by a four channel amp. What converter have you all found that works for you? I keep reading different things like the hiss and some other things.

When I was debating on whether to keep my factory HU, my researched pointed me to this which will plug into the factory harness and give me 4 RCA outs:

This is with a Non-Bose setup are pretty easy.

 

For bose, it is not so easy. Since there is external amp you will have to splice the wires as there is not plug and play device that I know off. You will have to use generic line-out converters (unless there is a way to tap the factory line level outputs somewhere). Something like this (x2):

 

http://www.amazon.com/PAC-SNI-35-Adjustabl...7399&sr=1-1

 

Definitely a bigger job but it can certainly be done.

 

As for front vs rear speakers, I didnt bother with the rears. I put all my money into the fronts since those are really the ones that will produce most of the sound. The rears are so buried and far removed from our ears that there isn't much point unless you are needing them for mid-bass with 6x9s or something. But a sub would be a better choice if one has the budget for it.

The None Bose adapter in the post from aesalazar is not the correct one , the correct one has no A after the model # the correct one for a truck is a PAC AOEM-GM1416, the unit with the A after is for HHR's and Pontiac G6's plus some other cars.

With a slight mod to the adapters wires you can tie back into the trucks speaker lines from the external amp.

monty, with the slight mod your talking about, you mean just so i can utilize factory wiring right?

 

Ive seen the hissing problem with the PAC converters on here. Someone said that if you add a resistor inbetween the unloaded lines it fixes the problem. has anyone tried this yet?

Oh and the reason im so adamant about keeping the factory unit is because of onstar and xm. ive been told that the xm is quite a hassle.

Thanks for pointing it out monty. I fixed the link to the right one.

Mine is non bose and I plan to just tie into the speaker wires near the rear seat to get my inputs to the amp to run my sub. I'm not a fan of using those PAC convertors. Seen too many issues.

Yes you retain all the factory wires no cuts or splices, if you remove the PAC harness and module everything is back to stock.

I have no hiss on my system that has a factory Nav with the Pac AOEM-GM1416 and Pioneer GM-9500F 4 channel amp, chimes , On Star is all as it was before the Nav upgrade sound wise.

Here are a couple pic's of the PAC harness after the cuts , if I can get them to post....

the rca's go to the amp from the PAC module and the 4 sets of cut wire are where the sound ties back into the PAC harness from the sound out on the amp

I wanted to keep the factory head unit for some other reasons, I don't have XM. I did not want extra adaptors to keep OnStar, steering wheel controls, or factory chimes. Not sure how common stolen stereos are these days, but if the theif looks in and sees the base stereo in the truck, and he is after stereos, he will pass on mine. The head unit in my truck is the only stock component in the sound system. Every thing else is hidden from view.

Ive been reading about speaker level inputs. Didnt know these existed now. They did not way back when i was big into audio lol. or atleast that i knew of. So im going that route first to see how it goes.

The first car audio amplifier that I ever saw, back in '90, had high level inputs. Most people, just never used them.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
