How to bypass my cars factory amp when adding a new radio and speakers

In this video we take you through the steps to bypass a factory amplifier when replacing your cars radio.

[@altruisticscoundrel]

7 years old and still helpful, useful, educational! Thank you!

[@erarandom1116]

I've been spending days trying to figure out why my 95 Explorer's speakers wouldn't work with my new deck, turns out it's all because of this premium sound amplifier in between the speakers and the wires in the dash now I know exactly 100% how to fix it. Nice video makes perfect sense now and know exactly how to bypass that crappy old amp.

[@fru7832]

New to doing this type of thing. I have a new found respect for audio system folks. My ram has been a nightmare for me. But this video is the only one that makes perfect sense. (After watching and absorbing the info after 4 or 5 times lol) Thank you so much!

[@seasparrow7427]

Nice. I have a 05' Jeep Grand Cherokee Lorado. It has a amp in back and a 12 pin going into the radio. I've been looking for days and you guys are the only ones that had useful info. Thank you!!!

[@khndenmark]

If you would do the same with a Range Rover Vogue 2001 with the amp in the back you will make thousands of people happy. A lot and I mean A LOT OF PEOPLE write in all kinds of Range Rover forums all over the internet how to bypass the factory amplifier, but NOBODY knows for sure. You guys will really help us. Regards from Denmark

THIS was exactly what I was going to try on my friend's 2000 Durango after I replaced the factory deck with a new Alpine head unit. In my 45+ years of installing car audio stuff (not full-time, just every car I've ever owned plus friends' and family members') this was the first one I had power at the new deck but no sound. That confirmed my power wires were correct and my ground was right, but no matter what I tried I could not get any sound from any speakers. Next, I disconnected all but the 2 powers and the ground, then started doing my "battery click test" learned 30 years ago to find each speaker (using any 1.5 volt battery, in my case a AA). I tried EVERY combination from the deck but got no clicks from any speaker, so I gave up for the day (it's winter here and it was getting COLD!). I then went home and googled it, only to find out it was SUPER COMMON. At least I could sleep better knowing it was nothing I screwed up! Next, I googled "2000 Dodge Durango stereo wiring" and found like 8 to 10 DIFFERENT versions, none of which had the same colors at the deck ends of the 2 harnesses! THAT really got me confused. So after finding out the reason nobody got any sound was because there was a factory amp, I new what I had to do next; bypass the factory amp! I was going to do your wire test at the amp to determine each speaker output, then just run new speaker wires from the Alpine to those 8 wires until I saw this video! Seems like a much neater connection method with less hassle of running new speaker wires. MY QUESTION NOW TO YOU IS THIS (PLEASE reply asap because I'm going back tomorrow to finish this job): regarding phase checking, if I don't have one of those fancy expensive phase-checking tools like you guys have, would reversing the AA battery also do the same thing? I mean, if the positive to one wire and the negative to another wire moved the speaker out one way, if I reversed those two wires on my AA battery and it moved the other way, that would give me my phase answer? Like if my cone moves IN when the 1.5v battery is touched one way, that would tell me which one is positive and negative? Or maybe I could just follow the same ones you guys found. Thanks for any help. This turned out to be a nightmare, and I told the Durango owner/friend this was going to be the LAST car stereo I replace for anyone buy myself! LOL! Probably not, but I was VERY frustrated that a simple head unit swap that only took a half hour ended up taking days and days of online research!!! OHHHH... ONE MORE QUESTION: if I decided to just run new speaker wires to the speaker outputs from the factory amp, would I need to unplug the other plug from the amp and remove the amp, or could I leave it there? THANKS FOR SUCH AN AWESOME VIDEO!

[@Steve-ec6ed]

I'd like to just say thank you for this. After watching this video I've decided I'm dropping my car off and letting a professional do this...

[@jlang1959]

😅🤣😭

[@TheBoofGod]

🤣🤣🤣🤣🤣

[@BassHead2020]

It’s really not that hard, well I’ve been doing this for quite some time now lol

[@tishlabelle1818]

Honestly you guys are the only people I watch when I need car audio help thank you so much for this video

[@JGreen46]

Tish Labelle amen to that I agree all the way everyone else is as informative with information as these guys

[@Clint_L]

Perfection as always. Love your work!!

[@FiveStarCarStereoInc]

Clint L thank you very much

[@Durango5.9Magnum]

THANK YOU!!! Bypassed my 1998 Durango with this video

[@MrTimdtoolman1]

Made perfect sense Brother. Great video! Thanks for your hard work.

[@FiveStarCarStereoInc]

Tim datoolman this was super confusing to make. I'm glad you liked it.

[@manuelgonzalesjr9621]

Thank you guys are Heroes Really so the sane two heads are better than one lol Great job

[@0664arn]

Thank you for all the info I hope it will be that easy with my 2013 VW Passat with fender system, I am replacing the amp and head unit.

[@tanneroverweg5598]

I know this is an older video, but I am looking to bypass the stock amp in my 99 dodge dakota with the infinity amp. I don't have all the tools to test the connections and stuff like that; so I was wondering if there was any way to find the color codes to the inputs and outputs so it makes it a little easier on me to bypass the amp? It's the same setup as this video, I just can't tell which colors match up with each other.

[@infidel24]

You guys make awesome videos, thank you and happy Easter

[@FiveStarCarStereoInc]

don198769 thank you and happy Easter too

[@justingardner4555]

Y'all do great work.

[@FiveStarCarStereoInc]

Justin Gardner thank you

[@truesurvivor6963]

Very detailed. Exactly what I needed. Thank you.

[@erikc3936]

Great video. I want to make sure I am understanding what you said at the beginning of the video. If I was going to install a Kenwood DNX696S in my 07 Town and Country and I was happy with the factory Infinity sound system. I don't have to by pass the amp. I can wire the radio directly to the factory harnesses. Is the correct? Would the Metra 70-6504 be the correct harnesses to accomplish this installation? Thanks for your time and knowledge.

[@JONJon-COD]

If the factory speakers was components on the front doors. Looking at a diagram the tweeter is the first to receive the wire and than to the 2 way subwoofers. Predicting a resistor between the connection of the tweeters. If I was using the factory speaker lines but wanted to use the aftermarket crossover to utilize the adjustable settings . Do I use the line from the tweeter or from the subwoofers for the aftermarket crossover . Would that line that may or may not have the resistors affect performance of the aftermarket components if it diid use a resistor or some sort of crossover

[@mtb2usa]

Do they sell a wiring harness or adaptor for an 08 Mazda mx-5 with a bose system. Keeping stock speakers just want a new head unit

[@nicderemer1]

great video. i had to watch it twice now but i think i can try this myself with my factory infinity system

[@FiveStarCarStereoInc]

+Nic Deremer cool hope I goes well

[@adambate1862]

Video was informative. The only thing I couldn’t really get is what wires did you solder together. The wires from the speakers to the radio. And how did you match them up

[@ericayala1738]

Hey I have a big question I have a Ford Flex so the car has 2 stock amps how would I do the sub one? Would it be the same?

[@DRO_056]

Should I do the same on Honda Civic SI 2009 or fire up the factory Amp instead? I've installed an aftermarket radio/navigator but the sound is not working when everything else works. Do you have a video for me? Thanks for your help.

[@twisteddreamz9977]

I have a 2017 focus ST and it came with the Sony premium sound system. I was told to leVe the factory amp in due to it being linked into the entire car. So my question is how do i bypass the factory crossovers to male an aftermarket system work? I have installed new speakers and a bigger subwoofer but dont know how to run the wiring due to factory installed Sony system

[@nuclearbum9858]

that was a somewhat easy one to do....great video guys

[@lvilaysing]

I wanna change out my speakers w. A factory amp alrdy changed out head unit... But I have a speaker that is blown should I wait to change out all 11 speakers at once or can I get a component set n hook it up w. The amp later

[@lisagedda1966]

You guys are awsome well explain why it comes in and out where's the fuses and more

[@adamdewey5793]

I did this on my 2008 Lancer, with factory Rockford Fosgate system. All works well, until the volume is turned to a decent level. Then, all sound cuts out, when the bass hits. What are your thoughts?

[@vonhoyte8226]

I have a a factory amplifier in 07 GMC Denali trying to hook up 4 channel amplifier. Do I run from speaker wire from speakers straight to 4 channel amplifier?

[@musibs]

Hello I have a 2011 Jeep compass with the Boston acoustic system in it I have already replaced the factory headunit and I would like to eventually add all new speakers to the vehicle and amplify them with an aftermarket amp can I just use rca out on the radio into the aftermarket speaker amp ?

[@Dnephilly]

"yay Chrysler boo everyone else" 🤣😂 great video, very well explained, I'm learning n this really helped me 👍🏻

[@dantepboyz]

If you replace the head unit and add a aftermarket amp do you need to keep the factory amp even if it gives a slight whine and doesn’t power all speakers anymore for a 2005 Acura tl

[@loveit2010ful]

Are you matching the positive and negative inputs with the positive and negative outputs?

[@jfuentes566]

On the wiring harness did you guys use one that had the support for a factory amp or use one that did not support the factory amp?

[@Llegando_Tarde]

Seen your videos before. Just noticed you are in clearwater! I have a 2013 buick encore headunit output are balanced diffirentials . Do you guys work with that

[@leeb.6841]

After you cut the speaker wires what did you solder them to?

[@isaiahvaldez24]

So once you found the positive and negative to each speaker you soldered them together? Only part I’m a little lost on. Would that not short the circuit? Like if RF speaker is white positive and white with black negative, you would connect the two?

[@JayLoveBeats]

Great video ! I comprehended everything you showed but how to make the loop plug for bypassing the amp ?

[@Andre-qx2ro]

Tryin gro bypass my factory amp and use a 4channel to power all the doors in my Audi A4.. The front speakers were powered by the HU (Pioneer AVH-1500) already.. so that was easy to get powered by the 4channel.. I tapped into the factory amp and spliced the left and right rear speaker wire then bridged those to the 4 channel.. For whatever reason I'm getting REALLY bad feedback from the rear speakers.. The front speakers are loud and crisp so I know it isn't the ground..and RCAs are all good..did I tap into the wrong wires? the only other wires that go to the speakers are input wires to the amp

[@shaunkoger4550]

Do you have any videos that you’re cars AC is included with the factory radio but I’m keeping the factory head unit but I want a five channel amp ? Honda

[@garymcintosh1067]

Hi guys....how r u both doing?....I hope fine...... I have a quick question....

Thanks.

[@user-je1pl4ek8z]

I have a 2003 acura cl with a bose system. I am running an aftermarket radio and a aftermarket amplifier. I used the signal from the rca jacks to the amp and speaker wire out of the amp to speaker wire to the harness that came the bose amp and there is no sound. Can you help.

[@Wyatt_Craig5]

Can you tell me what wires you spliced together on the amp?

[@MH-kd6fd]

Helpful Video, I appreciate you guys. I have a ‘97 land cruiser (80 series) with a premium 9 speaker set up. I’d like to bypass the amp. How do I bypass the factory amp and keep all 9 speakers functional? Currently have a pioneer AVH- 501EX installed. Worked well for a little over a month until I changed the front dash speakers and disconnected the amp now receiving an amp error code. Still receiving the code after I plug the amp back in. Help!! Lol

[@shanesubashe787]

I wish you had talked about suitable applications for using an amp bypass plug.

[@DaNKxCaRaMeL]

Just to be clear you dont need the connection that goes from the amp to the aftermarket head unit?

[@gb1971100]

What did you loop the wires to?

[@hunterwarren01]

I have a 1998 Jeep Cherokee Classic and I want to do this but whenever you skip over soldering the wires I get completely lost so I'm not able to do it. My Jeep has the exact same Chrysler Infinity amp.

Hi guys, I love you videos. Hey, I've got a special problem with my 2004 tundra quad cab. I put in a new stereo-- Pioneer. And it'll work for a few days. And I'll shut down then it'll come back on. There's no rhyme a reason it just works whenever it freaking. Feels like it one guy told me how to change the front base speaker so I did that didn't help. Somebody said the rear amplifier is the problem. No one behind the back seat. I don't know what to do. I'm about ready to tear it out, put my original back in.?????? I have not done anything with the rear amp as of yet, please help.
