1:16 Finally a troubleshooting guy that actually test the voltage! I can't count how many KZbinrs just skip the voltage like Amp regulators never fail!

[@milliondollarbike]

this is such a good video. Actually showing how to diagnose instead of assuming everyone just knows what youre talking about

[@fireboy5043]

Great video .. no bullshit. Just facts. Very good at making the way things work and how to use meter understandable..

[@frogsalesman1522]

I have power to all my wires and I did tests on everything except the fuse I checked that and it looked fine but I will check it now, if it’s none of those things what are some possibilities of what’s wrong? I have a mb quart rw-110a with the amp built in with the sub and it’s in protect mode when I try to use it

[@rk-life]

hey, i'm wondering if you have experienced installing aftermarket radio with honda stream premium audio factory amplifier. i've been looking for info like where the factory amp is located and which wire from the stock harness powers the amp. so far my android unit plays normally but no sound is coming out. if i wired a speaker directly to the player, there is audio. appreciate your assistance. thanks

[@chaboichillin]

So I have a cxa600.5 and it worked great for a very long time. I did have a sub problem and since replaced it with a new one, but it worked right away and now it doesn’t work at all after a short drive. Could it have blown that fast?

[@kaisblb7310]

Best explanation simple and clear

[@jefffralish]

Great tutorial, followed step by step and I have no measurable AC output from the speaker wires. I don't know what to do next.

[@motorcitybuds2117]

I have a zero gauge positive wire.. put my negative wire is a 4 gauge.. will that burn my amp out.?..now my amp no making no noises but tge light comes on ..on the amp.can somebody help me.

[@dapv144]

Right on time my good friend. Great video.

[@jptheinstallguy]

Yesssssir I was actually pretty excited to post this vid🤣😂

[@MKproSolution]

Thank you man!! I had a short with the remote wire I thought the amp was bad

[@6ixsidejoey661]

I recently changed my head unit, there was already an aftermarket radio in it I just changed to a different one, everything was just unplug and plug back in. Everything works except my amp and sub, the LED on my amp flashes red and blue and then turns off. Any ideas on what the problem is? The only wiring I had to do was cutting the remote wire off the old harness and connecting it to the new one. My amp is a Vertigo Power Acoustik 1600W

[@erikswenson9004]

Thanks!

[@snfox_elsavage1251]

So, I have a MTX and when I connect my positive, the ground side has sparks and is in safety mode, so you know how to fix that? I’ve changed the fuses but it’s still the same

[@joseluque4094]

I have been the whole weekend fighting with this exact problem with my amo, low voltage in the positive and perfect on the remote cable. I did check the fuse, it does look fine me. So as soon I can today I will replace the fuse if that doesn’t fixed the I’ll run a new wire. Thank you and I let you know what happens.

[@leftuonopen1679]

Did it work ?

[@kristyclement9025]

Hey guys. I've got 2 fosgate and P3 12s and a skar amp and DD in doors. Every once in a while. Whenever I turn up the base by the base knob or it hits hard, it doesn't go into protective mode, but it does cut out the base. the music keeps playing, but the base turns off. Wish do I do first? Could it be the amp itself and how can I know?

[@haitianway8781]

Helloo , I have a BELVA-BB200ABV2 amp. My amp goes to protect mode, I don't know why. I run a wire from the (+) battery to the 12v of the amp. I connect the REM of the amp to blue wire on the radio. I get the ground from the (-) pole of the battery. Any advice is greatly appreciated.

[@msburrage74]

So a blown speaker can make the amp go into protect mode? I do have one blown speaker and when I turn it up to loud my amp light will turn red and stop working. I bought the rockville 8in sub and amp combo so I know the amp is right for these speakers also.

[@joshuabiller6585]

Could there be something wrong with my bass knob ? I just bought a new one it works only if it is partly plugged in the sub

[@tanestewart6122]

How would you go about wireing a sing voice coil sub and a dual voice coil together

[@joejoetallone]

Question for the comments my amp got a lil warm and cut off now I don't have any bass it is not in protect mode and all my wires and fuses are good help ?

[@mattbrooks9928]

So I’ve had my system hooked up for years like 5-6. Rockford fosgate p3 12 2ohm and a 500 watt fosgate amp they actually pushes 620 watts. All of a sudden now when I turn it up it’s going into protect I never have all the settings all the way up and far as I can see all connections are good I can’t figure it out only does it on higher end of the volume

[@bobbycarmichael2562]

JP, great video man, And if you touched on this in the video, forgive me. Cause I completely missed it LOL. My subwoofer seems to cut off once I turn the volume to a certain level. When I looked at my amp I see it is in protect mode. If I keep the volume lower. Nothing happens but as soon as I turn it up Protect mode kicks in and subwoofer cuts out. Which of the tests you showed applied to that or did you not cover that specifically? I would appreciate your help brother

[@FahadKhan-xk2lb]

I have sony ax8100 and amplifiers was sony 4ch and sony mono block when i connects mono amp to sony ax8100 in subwoofer slot when sound was high my amp was cut off please suggest how to install

My kicker IQ 1000.5 amp makes an electric sizzle noise through the speakers after playing for 20 mins. It’s temporary then the music plays until it does it again. Any suggestions?

[@CarmenGonzalez-bm5zs]

I have a Kicker amp and I want to know about what does it mean or what do I have to do on REM what kind of wire do I use or how do I hook it up can you tell me

[@hateashburiednewjersey8471]

Well done. Thank u

[@cial577]

hi I have a Rockville rws 10ca 1000 amplified power car subwoofer enclosure and for some reason when i am playing music the sub will stop playing then when I play another it might turn on play for about 3 minutes then it may stop again. I thought that maybe it was the radio which was a factory radio now I have a jvc kw-560bt and I thought that fixed the problem but its doing the same thing . works when it wants to . I know that its getting power because the green light is on

[@user-ve7tp5hi5p]

Question i have 4000 watt taramp and when i turn on sound sfter a minutes or so the bass began to fade out until completely gone but if i turn off and back on bass comes back .....do i need to upgrade my electrical?

[@SONSTHREESIXTY]

Great video will Subscribe, J.P. did have loose ground, however still need to get the correct voltage match have levels inputs all the way down on channels 1/2 & 3/4 bridged. The 6X9 speakers are rated at 120 rms 240 max, so guessing Amp isn't 🤔 powerful enough to drive em. LET ME KNOW.

[@autasticreefing211]

I checked All the power and ground connections, I have over 12 volts I checked oms on the speaker outputs and it reads from 1 and drops to zero. Does this mean the problem lies with the sub?

[@mcdanielweldingcustomfabri6168]

The crazy thing is I had subscribe before you even mentioned it I liked after seeing the quality of the video you helped a Hugh pain the neck ✊😅😂

Thank you very much 🤜🏽🤛🏾💯💯

[@j0lla127]

The AMP power gauge accidentally touched the casing of the capacitor and caused a small spark. Does that short circuit anything and affect the SUB and AMP?

High i just try to install a new amp but it go straight to protection mode by the way my old amp work fine but it stay on when i turn off the car Can somebody tell me why this is happening?

[@mikeybigfoot1354]

I thought my door speakers were shorting on the sheet metal but I'm not sure they're connected to the amp while running subs that should be a separate circuit

[@rromarre]

For a while now my amp has been stuck in protect mode it started one day when i had them too loud and they stopped playing and started smoking so im assuming the amp is just done 100% but i want to make sure theres no fix before i buy a new one. Right now when i put all the wiring in the amp it stays with the blue light until i put the remote wire in and then it goes back into protect mode does anybody know what the problem is or have a fix. I've alr tried letting it sit with no wiring.

[@raymondmoreno7442]

Thank you for a great video really helpful

[@jptheinstallguy]

Thanks for watching

[@phillipmcnabb5633]

Why does my amp read 29 volts but my battery is at 13? I've been trying to figure this out. They worked fine until the other day. All the sudden my amp is reading high and isn't in protect mode until I hook speakers to it. But I tested speakers with multimeter and they good not blown. I'm soooo lost

[@schwiftyy4035]

It snowed recently and water got onto my amp and it got wet my subs started doing heartbeats so I just dc it and waited till it dried ig and now when I turn off the car my subs do a loud thump plz help

I have a 5000w orion amp connected 2 a 12" american bass sub. Had a pro install it worked great for around 8 months. All of a sudden now its popping and making weird noises the light keeps turning red. Once in a while it will run good then do it again

[@alexanderaguillermo3144]

I have this amp, I used 2 different power cables, 2 ground cables, and I disconnected everything and I still have the red light, but when I disconnect the control amp, no light appears. I tried another cable and the same thing happens. Rockford fosgate r2 blinking red light with amp control

what if the amp has the clipping color solid only? not protect mode

[@greengrind5089]

Bro, thank you so much and love the video. I’m not sure if this vid is gonna help me solve my problem, but after watching 10+ others I can say yours is the most useful and easy for someone like me who knows nothing to have a direction to go. That being said, if I do these tests and can’t solve it, would you be down to have me send you a video of the problem and you respond diagnosing it? (The video I send will just be to you and you can use or not use it in your response, just trying to figure my problem out). Either I haven’t been searching right, or I have a unicorn but my bass just thumped with no music connected and the engine turned off with the key out the ignition 😂 anyways,gonna try all this tomorrow and weather it works or not I’ll give an update

[@prankstation1015]

I like this guy

[@FlogrownlocalHB79]

Thanks bro I'm gonna try everything you mentioned tomorrow I feel like this video will help me fix my amp going on I protect

If you have a bad sub will it put the amp into safety?

My amp plays good on low but when the bass hits hard it makes a rumbling noise what could that be

Great video. I’ll use the multi meter and start checking these connections….

Anyone knows why my amp is in protection mode then when I remove my rca cables the red light turns off. Help!

[@BeardedKayakFishing]

I got one for ya. More frequently now, my amp will cut out. If I turn the bass up or volume up, it will come back on for a bit then cut off again. Sometimes it won't come back on at all.

did you ever get a fix?

Hey bro I have a kicker CXA 1800.1 with two Q-class L7 12's I recently upgraded my alternator and added a second power run and bigger grounds and a few fuses with a 29AH SCIB bank everything has been working fine for the past two weeks except for when I turn the car off if I open the door before everything completely shuts off it will burp my subs at Max volume for several seconds today I was checking it out clamping my setup and turned the car off and had the door open and it burped them louder than ever enough to shake the house and make the neighbors mad anyway I didn't think anything about it because it has happened several times but I went to get cigarettes about an hour ago and as soon as I turned the car on everything was fine except I was getting a major voltage drop at the positive input on the amp itself this has never happened before I literally never get voltage drop with the overkill power supply on a 2k amp so this has me really concerned I understood the amp and everything is completely fine throughout the rest of the car all the way to the lithium in the trunk right next to the amp so have I fried it it didn't have any music playing through it or anything and was dropping from 14.8 to 13.2 just driving to the gas station and it never did this before it burped today

I have a problem where my subs and amp were working fine for a year, now all of a sudden it only works when the truck is off, but once the car starts the amp instantly goes into protect mode. I swear I have go over everything 😩 ugh

[@jordankrall7497]

Your amp isn’t a 1 ohm stable amp and isn’t near enough to power those subs you gotta find a amp that makes 1200 watts RMS and is 1 ohm stable

[@johanvandermescht9237]

Install consists of head unit ,amp ,1*12"sub and 2*6.5 mids When i switch functions on the head unit say from tuner to aux or cd ,the amplifier switches off. Only when you switch back to tuner mode on the head unit,the amp turns back on I check all the connections..

[@arthurgreenwoodiii777]

Did you hook the amp turn on wire to the antenna turn on ?

[@jptheinstallguy]

Sounds like your remote wire is hooked up to the power antenna wire

[@brodihurt7606]

Hey the speakers randomly will be really loud and then it will go quiter as well as the sub what could be the problem

[@brodihurt7606]

And then it will sometimes be kinda Staticky

[@rodeubanks1283]

Will wiring speakers to .05 ohm make the amp turn off and on? Bass will cut in and out.

[@jptheinstallguy]

If your amp is not 0.5 ohm stable than that low of an ohm load will cause bass to go in and out

12 plus bro don't risk a fire

[@poochfazos]

Quite honestly bro my s*** just keeps my fuse keeps blowing. I don't know if it's cause there's too much power to my amp. It's an MTX audio terminator. I have no idea what. It requires a 20 amp fuse. So I just bought a 20 pack of those for like 4 bucks on Amazon at least til I get my powered subwoofer😎

[@Da_Ne847]

Amp is receiving power the speaker terminals aren’t reading anything on the multimeter.
