Be careful, I'm not a professional. I don't use cds anymore, everything stored on either dvd or sd card. Or I stream from my cellphone bluetooth. In-dash dvd players have all the modern capabilities for about a hundred bucks.

Very true. I had to do a replacement in the dash of my 99 crown vic, and it was very similar. I have already started research on the kit, and I have already picked out a new JVC unit that is blue tooth, cd, and auxiliary. SO, I can plug my iPhone in or blue tooth it. I was just curious about how to start because, at least on other vehicles, you have the little keys that you install and busts the head unit out. Now, I saw how it worked, and will research heavily before proceeding. Thank you !

Right, I just did a new install on my current Hummer with a double din touch screen head unit. I actually had to watch my own video again to relearn how I did it before... ^__O You can get a Onstar bypass for $60+ for the chimes and to remove any squeals or noises that the old system maybe causing...

Glad I was able to help.

What color is it?

What color is the wire??

Yeah, I sold that Hummer years ago. I did buy another one a couple years ago. My current Hummer has a bigger touchscreen head unit. I swapped all the door speakers plus a pillars, and removed the factory sub because it was shattered. -And I have 2 12 inch subs in the back. It sounds very crispy. Although I damaged my ears because the new a-pillar speakers were too loud. Doesn't matter anymore. I barely drive it, so I'm giving it away and will be purchasing the Hummer EV when it's released...

Seems we walk a similar path. My first hummer sounded like crap so I swapped the HU and all door speakers and added my own subs/amp. I was able to install everything without a single issue and used only the basic $5 GM harness. On my new (well new to me) hummer, the monsoon sounds amazing! It's hard to believe really. I was convinced the whole system was upgraded already, but upon inspection the door speakers look identical to the reg stocks on the old whip? Regardless I attempted to install a new HU without the recommended hmos-4 adapter after finding one local/retail was almost $200! Long story short after much headache and wasted time I had no choice but to order the adapter on Amazzon (paid $88). The adapter basically converts the high outs to low amp output to the amp to effectively make the new unit act as a powerless display like the monsoon 6 disc unit did before it. Trust that any sound you get without the adapter will sound horrible (think one channel with inverse polarity that becomes completely distorted at >/= 50% volume. So bottom line is learn from my mistakes and wasted time and just get the adapter from the start IF you wish to keep the monsoon. I watched this same video years back and was able to do exactly what you did, skipping the expensive harness with no problem. Late thanks for that by the way! I decided to pay it forward with this write up to help anyone else out there that's in the same position wanting to change the HU but keep the monsoon components. Can't emphasize enough how easy it was with GMOS-4 and how surprisingly good it sounds! It's nice having all the room free in the back too! If you are a stubborn DIYer like me, determined to get around such a ridiculously expensive harness, do yourself a solid and study the monsoon diagram first! Now if you don't have the monsoon or are replacing everything you can follow this video and it will indeed work; I've done it myself! Hope this helps someone!

You're right. That was in my diy days. I just go to the shop now. They have all the right stuff. My current setup is light years ahead of when I made this video. Different H3 now too. But this video might still be useful for someone who wants to install an aftermarket 100 dollar radio in their H3.

Matt Klimek hook it up to the positive wire of your cigarrette lighter the one that shuts off with the key and dont do what dude did for main power put a inline fuse in that wire if you do Jimmy rig it like that

Oh snap, I have no idea of the model... But I Googled it and ordered it on Ebay. Was like 10 bucks.

No harness will work on it's own. You have to wire the power elsewhere like an accessory fuse. Do so at your own risk. Any harness will work so long as it matches your vehicle. My recent install, I just tapped my power wire into the cigarette lighter. -It might be different for your vehicle.

I'd be lying if I offered any kind of answer. My subwoofer box was wide enough to cover the entire back seat. I just had my amp between the subwoofer box and the back seat.

Your unit is on, so power is not the issue. You maybe have to go back through your harness to make sure it's wired properly, grounded and check your radio settings. I'm not sure what else to do. If it persist, Google exactly what's happening, you might find the answer in a random forum somewhere.

If you have a monsoon system that means somwhere there is amps for each speaker usually attached to back of speakers so best bet look for a hummer wiring schematic online or dealer make sure it is for monsoon sys 1of2 things is going on either there is a extra signal wire to turn on and off amps or there are more wires and all amps need wired in for ground and power

SiccV6 same issue. Did you find a solution?

Never tried. Hummer is gone now though...

jesus barrio Are you getting power to the new console? There might be some special way you have to set up your wires...

Powers on and everything but no sound

jesus barrio It's your wire harness... Make sure you have the right one, hop on Ebay and grab a cheap one. But make sure everything is properly wired and that you've tried every option before spending additional cash.

Ok thanks. Any suggestions on brand

Stereo, wire harness? Not really.. I usually read a couple reviews online, if I don't see any negative reviews, I buy. Just Google the or look on Ebay for the components you need and look at the review. Not rich yet, so I navigate towards the cheaper brands...

I'd be lying if I answered your question... I only did research on the H3 and had a little help from a guy that worked at a custom shop.

JasenStl oh ok, can you list out everything i need, this is the first time I have ever done this

Sorry, I don't have time for that. It's been a while. Try to do your best from watching the video. If you get stuck, then come back and ask and I'll try to help. It's best to call a custom audio shop in your area, they will tell you what you need...

Whoa, that's way out of my league. I only know how to install subs and in-dash components. I pay someone else to do my alarm systems. Sounds like you're a bit more advances than me. My best advice is check Google for the forums or here on KZfaq for the video tutorials. Also, check your fuse box and make sure none of the fuses are blown.

k thanks

hey Casper 509 i had the same problem with my 2006 h3. unpug the battery for the night and plug it back up.

Probably the same setup... I'd try to run everything first and hook up the radio to see if it comes on.

thanks. I tried it last night and I did not need anything else. everything worked perfectly fine. Your video helped a lot too. Thank you for uploading.

Yes it did, but I never used it...

Sorry buddy, this video is on install not removal... Removal is very easy, just pull it out. ^__O But there are several kinds. Mine was aftermarket, so showing you how I took it out won't help a factory install.

Oh snap, I have no idea... I got rid of the Hummer 4 years ago. Sorry.

Honestly I can't remember. It was like 4 years ago. If you can find your manual, or Google it, there's a chart.

Good question... I'm not sure. But when I sold my Hummer, they told me the 4x4 was not functioning properly.

Thanks for responding I took to shop they said it was transmission transfer sumthn like dat plus Cadillac converter I just bought the hummer 2008 h3 108000miles three weeks later I had this problem but it wasn't till after I installed the radio this problem happened I told the dealership I bought it from it cost 800$ but he said if I can give him 350$ he'll put up the rest

Amp or acc fuse? You have to buy your own amp, stereo, and subwoofers. You can get them cheap on Amazon. The acc fuse I showed in the video is under the hood in the fuse box... Be careful and disconnect the battery before any installation. I'm not a professional, do it at your own risk... See ya.

i connect mine but it dont give me no sound on speakers

Factory amp is in the very rear interior panel (driver side) next to the subwoofer. Google image it and you'll have a good idea.

Ps wheres your butt connectors electrial tape is the devils playshop of probs only a temp fix till u can get it to shop

I'm good on going to school man. There is an infinite amount of free information on Google and KZfaq. I usually put fuses on everything, so there will never be a fire. -Maybe will have to replace a fuse. And that Hummer is long gone. I currently have a Chrysler 300 in it's place. I use the cigarette lighter now instead of the acc fuse. I'm no professional, just cheap. Whenever I run into an issue, I look it up online and solve it. Strangely enough, every problem I encounter has been solved by someone else and posted online already. I love being alive in this era. ^__O

Heh, thanks for subbing family...
