Man, I just put a new Kenwood head unit and couldn't get no sound out of any of the speakers and answers on Google were dead ends. I was beating my face off the dash and about ready to have a stroke until I came across your video and it was like the clouds parted and Sun started shining through. Thanks for all your hard work and sharing the information !!!

[@JoesCarSmartsNY]

So glad this helped you!!

[@christopherholliday1778]

This was a great how to video. I've had to bypass amplified stock systems like this many times in the past. Your video laid out the the location and wiring harness which was helpful and the wire schematic was spot on. Thanks for the help. Made the install a breeze.

[@dustin6816]

Thank you for the color diagram for speakers. I just put new speakers in my truck and after market radio in my 07 Ram mega cab

[@kirk422]

Thank you for showing everything well done. I have a 2010 ram slt, i think i drained my battery messing with my radio without the engine running now amp just stopped working for aux input only? Am, fm, sirius, dvd all still work fine amp bumps but in aux its a whisper with random subwoofer pops loud

[@JoesCarSmartsNY]

I would try disconnecting the battery to reset the radio and truck computer. Other than that I’m not sure.

[@kirk422]

Not sure if that AutoZone output line converter is wrong but maybe worth a try for me?

[@JoesCarSmartsNY]

@@kirk422 So the aux input is an adapter from Auto Zone?

[@BenDover4Mee]

I'm curious how you determined the polarity of the speaker wires going to the speakers? I can tell just by listening to the speakers when music is playing, but other than that would need to connect a dc power source to the wires and then test with a meter at each of the speaker terminals. How did you do it?

[@JoesCarSmartsNY]

I found a diagram online and used that to get started. Then, after it was all wired up, I confirmed polarity by checking for bass response as discussed on other comments here. Polarity was good according to the diagram. You’re right on about checking with DC power if needed. If I need to I use a 9V battery and quickly touch the wires and see if the speaker moves out or inward. If it moves outward than I’ve got the right polarity.

What if I want to bypass the factory amp and still use my dash speakers , what would I wire those to?

[@mikea4074]

Any help on getting the amp out.....the one bolt is a sob

[@JoesCarSmartsNY]

@@mikea4074 nope. I let it live right there.

[@justinb6425]

Well this make all my speakers play instead of how they are set up from the factory where the front door speakers only play bass?

[@JoesCarSmartsNY]

The factory door speakers don’t have tweeters, so if you replace them with new speakers and bypass this amp they will play full range.

[@justinb6425]

@@JoesCarSmartsNY awesome thank you so much for replying, your video helped me so much I was super frustrated thinking I did it wrong.

[@davidjosey378]

Question I have a 2006 Dodge ram truck with infinity speaker system. I had Best Buy upgrade my stock stereo with a Pioneer now the system will not fade. Best buy said that when you change stereos the Infinity system will not fade.. Is that right?

[@JoesCarSmartsNY]

Depends on how they wired it. They’re probably feeding the new radio into the factory amp. This video bypasses the amp which I prefer to do. Best Buy may not be willing/able to bypass it. If the fading is important to you, try finding a car audio shop in your area. Any good shop can do an amp bypass for you.

[@alexshalko9786]

Hey I have a question, do you have the wiring digram for the radio plugs for the oem navigation system. Someone stole my oem navigation and I got an aftermarket radio. All I need Is just a few pictures of the oem plugs so I can wire mine up. Please and thank you I can pay some $ also

[@JoesCarSmartsNY]

My best suggestion to you is to purchase the correct harness from Metra Electronics. Also, there is no switched power in that harness. A Metra digital harness creates the switched power for you via the Dodges digital BUS system.

[@Steve410811]

I have a question. I have the same system. Im gonna put a new reciever and new amplifiers. Can i just run. Rca jacks to the both amps and speaker wires to channels on the amp? I dont use the controls on steering wheel.

[@JoesCarSmartsNY]

Yes you can. You still need to get tie the speaker wires from the new amps to the wiring by the factory amp that goes to the speakers. Unless you want to run new wires from the new amps to the doors. I would usually just tie into the factory wires at the amp to get access to the factory speakers wires after the new amps.

[@evcnz]

Question for you. I bought a truck recently with this audio system in it and I believe it has the amp bypass. My radio turns on and I have sound but no bass and it sounds basic. Use to have bass before. I thought I smelt a fuse burn out but I’m not sure what it was. Any suggestions onto how I can fix this

[@JoesCarSmartsNY]

That’s not a lot to go on. I would put my ear to each door speaker and see if they’re making any sound. You might have blown out the door woofers and you’re only hearing the tweeters in the dash or pillar now. The smell could have been the woofers bowing. They give off an electrical burnt smell sometimes when that happens.

[@evcnz]

@@JoesCarSmartsNY this seems to be spot on. Your the man!

[@JoesCarSmartsNY]

@@evcnz You should also be checking the speaker wires in the door jamb like my other video: Repairing broken wires in a door jamb 2009 Dodge Ram kzbin.info/www/bejne/hZu1ZJtomNp8ipY This is a common problem unfortunately.

[@edwardkehling9698]

See I knew I wasnt crazy when I was trying blue to blue white, red to blue, cant tie it in with yellow or it wont turn on lol I do notice that the clip you pulled out was yellow/red, is this why my radio wont work red to red yellow to yellow? Would explain alot lol I have it powered with yellow and red tied up

[@JoesCarSmartsNY]

I think the problem you’re having is that the radios Yellow wire is battery power and the Red is switched power for when the truck is on. However, this truck doesn’t give us a switched power at the radio. You have to be sure you’re using a special harness/box that takes a digital signal from the trucks wiring and creates a switched power for you. Here’s a link…amzn.to/3LNG5zt

[@FlipSideGarage]

Do you need to plug it back or can leave the plugs unplugged since no longer needed?

[@JoesCarSmartsNY]

It can stay unplugged.

[@JonTheOG]

What about the dash speakers?

[@JoesCarSmartsNY]

What about them?

[@JonTheOG]

How did you hook them up?

[@JoesCarSmartsNY]

@@JonTheOG I did not hook them up. But the wire diagram in this videos description tells you the wire colors.

[@JonTheOG]

Gotcha, could you also do this and use the factory head unit?

[@JoesCarSmartsNY]

@JonTheOG I don’t know if the factory head unit has enough power to play the speakers. You could test it with one speaker to find out.

[@FlipSideGarage]

Is this the same as a 2011 with alpine system?

[@JoesCarSmartsNY]

Not sure.

[@jacobmartin6217]

Do you have to use the green box? I did the bypass and everything in my 03, stereo is acoustic as hell and doesn’t get loud, like it honestly sucks, yet same everything except head unit model sounded great in my 07 Chevy.

[@JoesCarSmartsNY]

If you did this exactly like I did the radio should sound good. If you reversed polarity on the speaker wires it will not sound good. To test for this you need to fade to the front left and see if the speaker sounds good and has some bass response. It probably will sound better by itself. Then balance to the center so you’re listening to both front speakers and no fears. If the bass you had disappears then your front woofers are out of phase. You have one wired backwards. If you have good bass with both front speakers playing, then your rear speakers might be out of phase. You could also have dying factory speakers overall.

[@BenDover4Mee]

@@JoesCarSmartsNY This was exactly my first thought based on his description., If polarity is reversed, it will cause an effect that sounds like it's increasing the stereo effect, but the base frequencies will cancel causing almost no bass response when the balance is in the middle (sound to bother speakers). Each speaker individually will sound nomal

[@jjthomas9656]

They make a pre wired bypass harness for $30,and one cig plug gives you R.A.P.S...

[@pickle5051]

They make a harness for this I believe

[@JoesCarSmartsNY]

Yes they do.

[@tankie915]

@@JoesCarSmartsNYis there a harness to let me keep the amp and use it with after market stereo?

[@JoesCarSmartsNY]

@@tankie915 I don’t think so. I think the problem is that the amp is turned on by a digital signal from the factory radio. I don’t think there’s a harness that duplicates that signal. However, Metra Electronics would be the company to talk to about that for sure.

[@jimmyavalos5357]

Can i get the wiring colors

[@JoesCarSmartsNY]

Check the video description. It’s mentioned in the video if you watch the video.

[@6nzchencho752]

Can I just wire my stereo off the battery with a fuse. And run new speaker wires ?

[@JoesCarSmartsNY]

There is already constant battery power at the radio, but you will need to find a wire that gives you an accessory power signal that only activates when the key is on. Otherwise you have to use a toggle switch to turn you radio off / on when you want it to be powered on. The harness does all that for you. I know it costs money, but it saves a ton of time. You can run your own speaker wires, but that is actually more work than this is. This way you only need to run from the radio to the glove box area. Otherwise you have to run all the way to each speaker and getting through the door boots is not super easy either.

[@6nzchencho752]

@@JoesCarSmartsNY I was told that the door speakers only produce bass due to the the way the amp is set up. So it’s pointless to run good speakers if you won’t really be able to get all the benefits. Unless I also get some good dash speakers.

[@6nzchencho752]

Also I don’t have factory Nav and At this point won’t really matter to me if I get that $100 kit with the box and the harness. Which I read that box allows for a aftermarket head unit install. Also is there any way I can upgrade that factory amp ? Maybe throw something to help me now play the door speaks with all frequencies? Line our converters ?

[@JoesCarSmartsNY]

@@6nzchencho752 If you bypass the factory amp and install good door speakers, the door speakers get full range. The door speakers are only limited to bass by the factory amp. Best (most cost effective) option is to bypass amp according to my instructions, put new speakers in doors and disconnect dash speakers. You will get clean full range sound out of the doors.

[@JoesCarSmartsNY]

@@6nzchencho752 You can put in a small amp like a Soundstream Stealth to power your speakers. That would fit behind the glove box. amzn.to/3UGIP6s

Isn't there a wire I could send power through to turn this amp on?

Are you trying to keep the factory amp in place while installing a new radio?

@@JoesCarSmartsNY I was trying to. If I can't figure it out, I'm going to use you method

[@JoesCarSmartsNY]

@@clasicradiolover I think the amp turn on is a digital signal. I don’t think you can just send it 12V to turn it on. Do you have the adapter harness for this truck? I think I mention it in the video.

[@clasicradiolover]

@@JoesCarSmartsNY I didn't see that in the description. I have seen Crutchfield selling something. But $65 is too expensive. I'll try your method

[@JoesCarSmartsNY]

@@clasicradiolover You will need something like this to get accessory power for the new radio: amzn.to/3QRPBDW There is no accessory power at the factory radio. You’ll need to research the specifics of your original radio (NAVIGATION / ONSTAR ETC) before choosing an adapter harness. The video for amp bypass does not get you the accessory power you need for the radio. It just lets the speaker outputs from your new radio go around the factory amp and to the speakers.

[@prodBrainShot]

is there no way to turn on the amp instead of bypassing, i thought i was going crazy when the speakers where not playing sound lmfao

[@JoesCarSmartsNY]

My understanding is that the OEM radio activated the amplifier with a digital signal we can’t duplicate. Metra Electronics offers an amp bypass harness if that’s easier for you. It’s supposed to just bridge the two plugs together instead of all the splicing.

[@prodBrainShot]

@@JoesCarSmartsNY good to know, ima just remove it
