Does it do it when car is not moving? If it does'nt then it is a bad connection in the amp itself or outside the amp. Check all your external connection well, it is easy to pass a bad connection up without knowing it. I recomend checking every connection, redoing the connections. Then you can rule that out and may find the problem. If connections don't fix problem let me know i'll be glad to help. I have my own amp repair business and people send me there amps from all over the U.S. Just send me a message and
I'll take you thru some steps to diagnose the amp if problem persists after connection checks. Good luck, hope to hear from you!

Cold solder or lose connection in the amplfiier, or a poor connection with the wiring. The vibration of the movement of the car is causing the intermittants.

No sound from speakers, but yes from sub. Grounding issue?

Grounding issues are just simply earth connections that are either loose or are badly soldered. Sometimes with bad soldering a knock on the unit can make it play. It's just a question of going inside and looking - with a lens sometimes - at soldering joints - wire connections and screws fixing. Random cut outs certainly sound like bad soldering problems etc. The only other cause is heat sensitive devices, which shut down when too hot. But I wouldn't jump to that conclusion just yet.

My subwoofers randomly cut out while driving. In and out in and out. But not the radio and treble. Only the bass. i have a cap hooked up so power shouldnt be an issue

First of all, how hard are you running them. And what system, wattage, and amp do you have. If you have a 2 or more channel amp, and you are bridging it. STOP, doing so does add power to the subs, but it also can add power that the subs cannot handle, and an amount of heat the amp cannot handle. So your amp could be over heating... good luck

it is most definately a power issue your amp is cutting out due to over juicing (assuming your amp is solely hooked up to your subs and your deck is powering hi's low's mid's) as a safety precaution amp will turn off whenever your cars alternator start putting out more than 9-11 I would suggest taking a voltmeter to your car battery to see what it is at while your idling as its difficult to due while driving and adding a couple to account for the added juice from alternator running at higher speeds if it seems like it would be in the 9-11 range you may need a new alternator or battery

CHT12 speaker cuts out randomly have to turn off and on to get sound

Here is something you can try.

On your source check the output level for your sub.
Try setting up at a higher level, if at 1 set it for 2 or 3
Then adjust the volume control on the sub down to mach the speaker volume level.

Amp staying on but cutting out?

Hello Willb2396,

Actually you answered your own question in your paragraph. I draw your attention to your statement of:
"It will work for as long as I'm driving I will park my car, and when I turn it back on every thing will be working just fine and, then a couple minutes later, amp cuts out and won't hit for a couple hours or a couple days.... I have checked the sub multiple times and I don't see it being the sub or the amp"

You are correct it is neither the Sub nor the Amp. The problem is either your voltage regulator or your alternator. one and or the other is going bad.

Here is some advice check your ground wires, the buy a dual alternator kit, it contains the parts you will need to add an additional alternator to your car. This will provide the power you need.

I hope this helps,

Thank you,

NICE SUB! I have found that when this happens, there is a good possiblity that there is a loose connection on the speaker, or on the crossover network inside the sub. The real only way to test this sub to see if it is indeed the sub, would be to test it in real time under controlled conditions. That would involve hooking the sub up to a power amp that has a tone generator attached to the input and driving the sub to its rated capacity. Other then that, you could probe around to see if you have or can see any loose connections inside the sub BUT I would not recommend you doing this while the amp is on as you could short out the output stage in the amp. My best advice would be to take or send this sub into an authorized Yamaha repair station. Good Luck
