How to bypass your factory amplifier

[@sheriffpuma]

Thanks for your explanation. The guy at best buy pissin me off by not helping me understand this at all, but you explained exactly what I needed to know in plain English and you showing me and all that. Now, why couldn't he just do that for me real quick? Absurd. Anyways. Thank you.

Once you tapped in to that speaker wire and bridge those...do not plug that plug back into the amp? I noticed you left it out.. wasn't sure if that amp was powering other things in the car...

[@kingsoutdoors4379]

You can use a 9volt battery and a couple clip leads to find polarity on a speaker 👍

Yes sir!!!!!

[@uttitanfan]

@@Jenuin I use a AAA battery.

Yo. This was so helpful! I had to watch a few times to understand all the way but when I got it, I GOT IT! Headunit sounds great and now I have CarPlay in my ‘04 Infiniti

[@jerrywinchell4308]

Instead of running new wires you could just jump the wires from the input side of the amp plug to outside of the amp plug bypassing the amp, you made a lot more work for yourself man.

[@jeremyclark9705]

Would that work?

[@ericnicolini-calderon1337]

@@jeremyclark9705 wouldnt recommend but yes it does work. but it’s like plugging an extension cord into itself but there’s a power wire that powers the extension (so it’s always on aka dead battery in the mornings) IF IM NOT WRONG

[@whoopdeedo83]

@@ericnicolini-calderon1337 Old comment but for others who might stumble on this.. If you jump the speaker wires from the input side of the amp to the output side you would bypass the amp entirely. You would only hook up the speaker wires, meaning the factory amp would *not* turn on (no signal wire to tell it to power on) and therefore it wouldn't drain your battery.

[@jameshalford4699]

Sorry im not technical minded but getting sick of this amp picking and choosing when i can have my radio sound on in simple terms how can i “jump” the amp someone mention optical cable bypass ??

[@danielfaust2456]

That's what brought me here. The fuse under hood pops as soon as I put it in and I'm wondering if I can just cut them and splice them together just to get sound. I have a car that's got a system but in the minivan I'm not tying to do all that. Just want it to work.

[@jlev505]

Gotta love laying down in trucks. Did the same thing in my 2016 Infiniti Q50 RS 400. Installed the audio control DM810 with 10 channels of highs and mids, then a JL HD1200 with a JL 12W7AE. Sounds so much better than the worthless blows system.

[@IMedinaIM8]

I’ve been trying to figure out how to do this for a while!! You couldn’t have explained all this any better man, thank you!!!!!

[@prestige8161]

You can bypass the amp with a harness from OWC Upgrades. It just plugs into the factory connections and then you connect your aftermarket gear to it. Best money I ever spent.

[@unknownc2k]

do you know how tu get the harness for a 2015 nissan sentra??

[@prestige8161]

@@unknownc2k Yeah. The company I mentioned above has them. Just google the name and you'll see the website.

[@jamiedownie6746]

To find correct phase without a phase tester you can also use a 1.5 battery just touch the speaker leads to both ends of battery and the other ends of the wire to speaker if you if you have correct leads the speaker will pop out if not it will suck in.

[@KL_daddy]

I’m wondering can you just just take out the factory amp and tap right into wire harness with a 4 channel amp. I’m trying to get a louder clearer sound in my Denali. I guess I could still run it the way jp did just would have to run the power wire to the battery but I’m wondering if I could use the power wire that’s powering the factory amp and would the gauge be efficient enough

[@andysims6478]

I also hav a Altima. Can you pls tell me what wires are to the amp from head unit and what wires are from amp to speakers? I’m gonna bypass factory amp till I get a 4ch

[@Eccentricvoice77]

Excellent video, you explained everything clear. My saying I always use for speaker wires is Green and white ain't right. Thanks bro!

[@hgfdksk17]

When doing this, should I disconnect both terminals from car battery ?

[@coledaddy818]

Will unplugging the amp do away with bose pulling power out of the speakers at higher volume. After 75%-100 it doesn't get louder

[@atFullStrength]

One thing though. The higher wattage of the new amps your putting in and the increase in amperage, the factory gauge wires aren't big enough. So it's better to run new wiring and not power and speaker wires together throughout the entire run.

[@terryreyes1125]

Wrong. Its enough for speakers. That only applies to woofers

[@fatguyalwayseats]

@@terryreyes1125 yes but the factory power wire might need to be replaced

[@fatguyalwayseats]

And ground

[@markmalasics8413]

There's a great tool out there to test the speaker wires to see which speaking is on the other end (popping it) AND determine polarity. And you probably already have one at home! No need to spend more money. It's called a 9V Battery. Ever-Ready and Duracell make some nice ones. All you do is use a couple of small electronics jumper cables, or even the bare end of the wires if you don't mind dealing with shorter wires, and place the battery across the wires. That's it! You'll hear the speaker pop, and you'll also be able to see which direction the cone moves to verify polarity. Just make a note of which wire is hooked up to the + on the battery.

[@muthatrucka76]

Yep..That's what I was gonna comment...One thing you forgot for the novice stereophiles...If the cone moves outward first..the polarity is right...sucks in..backwards...

[@mdpatrick2225]

If I have a dsp, can I just run everything thru it, to my aftermarket amps(3), then remove the factory amp?

[@sammythebull2240]

Great video, bro. 1 question: Can I just cut all wires from connector side of harness ( factory amp side of harness ) , then tie my new speaker lead-wires into that connector harness, from the NEW amplifier, and reconnect connector side of harness back into factory harness? That should get power to all speakers if done correctly, then I can run power and ground, may not even need remote wire to radio bc factory harness has remote which I have connected behind aftermarket headunit already. I already installed a Interface kit to retain steering wheel controls- which is working great, but factory amp keeps cutting off, so this is my plan to bypass.

JP, clarity in Camaro fog! Thanks for that! Sorry this is long. I'm asking this question in becasue I need a little guidance. I have a 2017 Camaro 1LT, non-bose "a nightmare for audio upgrade. I replaced all speakers with 500 watt Kickers (2 ohm), but the horrible factory amp only pushes about 40 watts and happens to control many other functions. Shameful for a Camaro right!? Do you think I can use your method to bypass the factory amp, "without changing the head unit". Everything on my vehicle is controlled from the head unit, changing is not an option. In my mind's eye, I use your procedure on the amp output side, and wire directly to the new 4 channel amp (make still undetermined), input, then connect the speakers to the amp output. Would you do it this way? Or should I take only the audio signal coming from the head unit and wire (bypass) to the new amp? I feel like I should use some kind of digital level control mid-stream, before the new amp input. If you help me through this, I will put your banner on my car! I show it every Friday here in Orlando. Thanks David

Why didn't you just jump the wires from one harness to another (therefore bypassing the amp) and use the Metra 7551 (or whatever the connector is that allows for speaker level connection behind the head unit) which should let you use the cars stock wires to carry the signal to the speakers?

I got a 2007 Dodge Charger and it has a factory amp, but when I unplugged it, it threw the whole car off. Could I just bypass the amp and plug the rest of the wires back into the factory amp and ride out like that?
