2014+ impala Bose stereo system bypass and upgrade

I just went onto google and punched in that part # for the stereo kit, it seems it is available.

I donít know about wiring harness or steering wheel control compatibility.
And if u have a backup cam make sure to get the parts to make that all work too

I have the mylink set up 8Ē screen and nav/w Apple car play, and really like how that all works. So the dsp route for me is what in going to do.

You're telling me... I had all my stuff installed originally by a shop and the guy completely F-ed me; so I've literally redone EVERYTHING myself besides the (post-?) amp pin-out that feeds my dsp (I'll check it again tomorrow).

Had to learn the hard way, but I know my stuff for the most part now

Well donít be afraid to ask if u have a question bud.

This bypass thatís coming out is supposed to eliminate a ton of the install headaches on our cars. I was going to go with summing the after amp signal but found out these were coming out so I have been hanging tight.

Do u have photos of your install?? And what youíre using??

Just got done tearing the dash down and putting it back together... The climate controls still work without the radio!

My Metra dash kit came in today too so I went ahead and just put the majority of it in while I was at it.

My radio comes in tomorrow (Kenwood double din), but I'm still on the fence about what kit I'm going to go with. Most likely the PAC RP5-GM51 cause it's cheaper than the Axxess one, but I will make up my mind tomorrow. Probably overnight it from crutchfield, or try to find it locally so I can have it in by the weekend and finally enjoy some clean sounds.

I'll also update with some build pics once I'm done!

Sorry, it's been a while. I'll jump right into it....

So I installed my Kenwood DDX775BH with the Metra/Axxess Kit GM-MOST-02. (pricey still at almost $300 for the dash kit and harness; I bought both of mine off carID as they were the only ones that had it at the time).

I wound up having a shop do the headunit install because I was lazy af and they had a bar next door (!!). I tore the dash completely down for them and also ran my 6 channel pre-outs to the DSP so they had minimal work to actually do and everything came out nice. With that Axxess kit, the Onstar app controls also still work fine with my vehicle so that's a nice little bonus.

I also added a Sirius XM module (SXV300) to get my XM back after not having it for a few weeks with the new radio. At first I used the included antenna from the XM module, but reception was piss poor no matter where I placed it inside the cabin/dash because I didn't want to add the damn thing to the exterior on the roof... So I wound up buying an adapter to use the factory antenna fin on the roof; link for that here: XMF-SMB FAKRA to 3rd party Satellite Radios :: Car Stereos and components. I bought a 6 foot extension but I'm fairly sure 3 foot would be enough. The cable needs to run from the inside of the dash (above the glove box) where the XM tuner module sits (or wherever you have it placed after installing to the back of the radio) to the bottom passenger kick panel where you'll connect it to the factory XM connector (I believe its the gold/yellow connector down there). Once I did this, the reception is the same as factory, no more intermittent dropouts.

Overall, sound quality is superb now with the new radio and I have a nice looking radio with more features.


Currently I'm working on installing an aftermarket dash cam, Crux CUL-03. It just shipped out today so maybe I'll give another update if it winds up working out. Pretty sure it should fit on that lip right above the license plate though.

Also, I'm going to sound deaden my floor and roof next (everything else - all doors and entire trunk - is deadened to the max with CLD, CCF, and MLV all layered up) and then make a MDF amp rack panel to tidy up all my amps and wiring (currently in a bit of a rats nest, but not too bad)


That's about it for now. If you have any questions feel free to ask away, I pretty much know this damn car inside and out now audio-wise.

Also a side note for everyone:
Crutchfield doesn't really have an up-to-date list of fitment for either radios, nor speakers for our cars (at least at the time I did everything).

The speaker baffles I used for my new speakers are listed here and DO FIT, same exact bracket/baffle as OEM:
- Front 6x9 bracket for new 6.5" woofer - Metra 82-3005 Speaker Mounting Brackets - https://www.crutchfield.com/p_120823...mnews=13521804. To ensure a speaker will fit, I plugged in a 2016 Silverado and used that as my fitment guide. My new speakers went in like butter
- Rear door speaker 6.5" bracket - Scosche SAGMHR-634 - https://www.crutchfield.com/p_142SMH...mnews=13521804

Did this car have a touch screen from the factory or was it a base level with the basic radio ? Another question: How do you change the various vehicle settings and options that were accessible in the factory head unit ?

No touch screen, was stuck with the ugly 4.2 inch radio before.

And whatever settings were set on the OEM radio before are there to stay now (not that there were even many settings to begin with on the 4 inch radios; pretty much the only things available to mess with were lights and door settings upon key fob unlock/lock, that's about it)

Finally got around to upgrading the alternator

It was a bigger pain than expected (you have to pull the engine mount to get to the serpentine belt tensioner).

Took a couple hours to do.

Hereís what I went with

Mechman elite 320amp alternator

Smaller serpentine belt (3/4Ē shorter than stock)

The pulley on the new alternator is smaller (hence making it spin faster).

I havenít been able to test it with my subwoofer set up yet. I removed the subwoofer and amplifier temporarily so I can start sound deadening the car completely. And build a nice amplifier rack for my 2 amps.

More to come soon.
