Dude, the timing of this video is just perfect! I've experienced this issue last week. Got a custom sound system installed by my local Car Audio shop and after a month, the amp would just shut down randomly. After investigating, the wires on the side of the amp got loose for some reasons. Easely fixed, but I gotta say, I was freaking out when this happened lol. Awesome video as always! 😉

What car? Ford f350?

One other thing to mention, when testing voltage on the power and remote wires, if you have low or no voltage on both the power AND remote wires, the ground is probably faulty. Test the wires again with the black probe of the meter grounded to the chassis to confirm.

Ive recently fitted new rear speakers, sub and amp was working fine prior to this, after install all speakers work but no power on to amp Going to check through some these tips tomorrow

3 minutes in of watching this and already figured out my issue great vid

Thank you so much Mark ❤ I accidentally reversed polarity of input power and blew up my amp fuses with sparks. Replaced my fuses and it plays fine now 👍

Mark, quick question I accidentally plugged the ground and Power in reverse I saw Sparks when I put the ground in the power cable in the ground. Did it again this time no sparks. Fuse good. could you please be so kind and tell me what steps to take next should I check for a protection diode across the + & - like ameture radio amps have. Should I try hooking it up the right way and see what happens I'm afraid to do so in case I damage it if it isn't already damaged. let me know please bro thank you very much. It's old school crunch p-1000 1k rms 5 ch amp 70 amp fuse. Fyi: the remote was not plunged in

Now this is diag! Great video!

Good video. Dealing with this rn with a brand new head unit not putting out voltage from the line outputs. Going to double check with a meter playing a test tone, but looks like I’ll be sending it back to Crutchfield.

If you have no remote wire the amp shuts off ? Right ? Cause I’m having the problem of no power to my amp

My voltage at my speaker inputs on my subwoofer amplifier are about 12 volts with the gain all the way turned up what could be the cause of this? It used to go higher than that could it be my alternator going bad?

Top tip for hyundai/Kia drivers out there. If you want to upgrade your audio and got a SPDIF factory Amp. Save up and just completely remove and replace the factory radio and amp and get some speed wire for your aftermarket gear. You do not want to know the hell you'll go through trying to work around that amp/radio instead of just gutting it.

I’m using an adapter to my stock head unit and the trigger switch wire broke. Will it work if I wire the trigger switch to a 12 Volt aux switch on my truck?

I have an amplifier and subwoofer already, but want to add more power and sound. What should I get?

Recently got a kicker cxa800.1 and it worked the first day but the next it cut out and after testing the power and ground it was reading 6Volts. I have no idea what to do cause my lines seem snug.

How do u trouble shoot the other thing... for lowering the frequency so the amp can work... but it doesn't- still I checked everything and it still won't work. If the speaker is blown won't it make SOME noise?

Here is a question you should address. Does the shape of your sealed subwoofer box affect how it plays or sounds? For example say you build a custom L-shaped box to fit in your vehicle versus a square or rectangle.

So I bought a home system subwoofer, I get power to the unit and I can actually run signal through it into my studio monitors/ and successfully get sound through my studio monitors!!! but my subwoofer is just not firing at all.??? Has no sound. I have put my multimeter up to it and it is reading 3.2 ohms. Its a 4 ohm subwoofer. Can't seem to diagnose it unless that means its a bad woofer. It has a slight ruffle sound when I press it in really hard... any suggestions?

Several months back, I had a situation where my amp had battery voltage while the head unit was off, but as soon as the remote line was energized by turning on the head unit, the battery voltage at the amp dropped to zero. Turned out to be a faulty/intermittent at the point where the positive power wire was tapped into the system. I replaced the wire with a slightly larger guage wire, connected properly at the battery instead under the dash at the fuse box ( was using a previously installed wire, by a previous owner ) and the problem was fixed. Just something to be on the look out for in similar situations.

I just recently got two JL audio 12s, lc2i pro, and a jbl amp I love them but every time I accelerate in my car it makes a terrible rumbling noise almost as if the sound of the engine is coming through the subs, I’m very new to car audio systems and I’m not very educated on how they work. The only time the sound gets slightly better is if I turn down the bass completely which pretty much defeats the purpose of the subs. Does anyone know what may be the issue and how I could fix it?

Hi there! I have a question. My preamp outputs on my aftermarket head unit are 2 volts. Does more voltage equal more power out of my amplifier in any way? What can I do if so? Thank you!

@danielabrams555

The amplifiers gain control is used to set the amplifier up for the correct signal input voltage. You will need to use more gain with a weaker input signal. When tuned properly, there will not be any difference in amplifier output level regardless of the signal input level. The advantage to having a higher voltage signal is an improved signal to noise ratio.

One way to get a higher voltage on your preouts is to use a " line driver " which, Mark has reviewed one by AudioControl here on this channel. While, as Daniel said, the higher voltage won't make your amp any louder, it WILL however make your overall sound quality MUCH better.

I love the audio control amp I have, but when I had it professionally installed using the gto it fried the battery in my wife's 2020 Jeep. And it is actually the same amp being used in this video. So in new cars w everything integrated into the stereo, be careful. Every time the key fob was used, doors open, etc, it was powering the amp on.

I have checked everything on mine everything checks out. The only thing I can come up with is the high output alternator from js alternators I have is keeping me at a steady 15.5v and that is too much for the amp which is a kicker ca1200.1. Can you do a video on a solution for this issue or does anyone have a solution for this?

Your amp should be wired to/pull from the battery, not the alternator... The alternator puts out more when the engine is under load, idle is 15.5... the alternator is to charge the battery, the battery runs all the electronics/lights, engine start, ect... Not the alternator.

What if you do the RCA check with your phone and a 35 mm Jack and you don't get any sound

Here is where I’m at with my subwoofer install (this is my first time and I am struggling at every turn): TLDR: my sub is extremely quiet even when I crank every knob to the maximum. Like so quiet there is almost no movement on the sub at all and I have to put my head on it to see if it’s on. I have an AudioControl LC2i Pro. I have crimped the rear speaker wire and connected that to the LC2i high speaker input and then I jumped the left to the right so both sides were getting the same signal. I am vampyring the power and ground on the LC2i from the amp with 12 gauge wire. The amp is an 800 watt D class using 4 gauge wire that is connected to the car battery with an 80 amp fuse. The negative is connected with 4 gauge wire to a bolt that is connected to the negative battery terminal. When measuring the battery with the car turned on (but not the engine running) the LC2i and the amp both show 12.4 on the multimeter. I then ran a tone through the car speakers and see that the RCA cables plugged into the LC2i are sending signal. I plugged the RCA cables from the bass output on the LC2i into the amp. First annoyance is that both the LC2i and the amp have knobs that control the bass. I’m not sure if I need to have them both plugged in and then find some synchronized levels. Because I’m not using a remote wire from the head unit, I am using the GTO option on the LC2i and that seems to keep everything powered properly. I am also using the remote out on the LC2i to the remote in on the amp. Last settings for the LC2i are the load select which I have at 20kO and the bass output level which I have in the middle. I didn’t do anything with the accubass and just have them at the minimum. As for the amp, it has a setting for bass boost which I have off (0DB), low pass frequency which I have set to allow all low frequencies, high pass frequency which is set around the middle which should give it a cap of around 100hz, and then it has the RCA input from the LC2i. As mentioned before it is connected to power and turns on without issue. The output it has are 2 + and 2 - speaker terminals that appear to be jumped inside the unit according to my continuity test so I only have 1 12/14 gauge wire (not 100% sure which it is) connected to those and then to the sub. In relation to the video, the amp is turning on. RCA is showing an AC voltage. I am detecting a signal from the speaker wire. At this point I can hear a faint sound coming out of the sub, but it is extremely quiet. I am hoping there is something obvious I am doing wrong. Again, this is my first time wiring this up and I basically did it from your videos and reading posts on Reddit/the internet. I would easily pay someone to do it for me but no one will touch my car as it’s a 2022 and there is currently no public info on it, even cruchfield is blank. So any help would be greatly appreciated!!

My amp doesn't come on and it's getting power. Fuses are ok but nothing. Internal issue? I guess it's garbage time.

I have a problem with a salt 6 that has very little play time on it. It will loose signal through the rca inputs within a minute of play time. I switch my rca cable to the slave input and it works fine. And sundown Audio tested it and said it works fine. I've never had this problem happen before. Basically this amp only works in slave mode. Anyone out there could give me some advice on what could be the problem.

As a automotive tech that doesnt work on the audio side that had no idea this was how they worked. My mustang hadnt had any speaker working or amp for a year. I knew i had power coming in but had no idea what was going on with it. Ended up being the amp uses the headunit ac signal from the music (static ac when on) to turn on the amp. And for some reason it lost that functionality. Jump to the key on signal from power like you suowed and it came to life. So i took the interior apart and ran a signal wire from the headunits factory key on power. And now it works. Thanks.

How to connect the fuses and not needing them, actually!?

My problem is that I can measure power on the wires before connecting them to the amp, but after connection the power is below 2-3 volts. All fuses are good 😢

My eq is not sending out any single to the head unit and I know that it’s getting the signal from the amplifier

A couple of tips. Amp fuses should be tested out the amp, or the multimeter could be damaged. If you want to test them connected to the amp, a better way to do that is by checking them in high current mode, as an amperimeter, 10A in most multimeters, and set the volume really low. If a fuse is blown, when you connect the amperimeter the circuit will be closed by it, turning on the amp. If fuse isn't blown, the meter will just show 0 Amps. To check remote speakers wiring, even if they have any kind of filter, we should just disconnect them from the amp, and set the meter in ohms. If meter shows infinite value, speaker may be disconnected. If don't, we have two possible chances: if it's a low frequency speaker, it should show a low value on ohms, because if it is even filtered, low pass filters should have low impact on impedance (coil resistence). In a mid/high range speaker, we should have much higher resistance, but never an infinite value. And to check speaker wiring, oldstyle way, is using a 1.5V battery (AA or AAA) or even 9V in high power speakers. By fast connecting/disconnecting the battery directly to the speaker we should heat little "toc" noises from the speaker, if it's ok. Please don't use any power supply or car's battery to do this, DC is really harmfull to speakers and we need to use a low volt, low current drain battery just to fast checking, higher voltages or high amp capabilities will end blowing your speaker coil.
