Sounds like you might have a problem in the output stage and that it hasn't completely blown out just yet. I'd expect it to get worse soon, like not working at all or maybe smoke coming out or both. You might consider seeing a repair tech. soon. Good luck.

Why does my yamaha 15 inch speaker keeps cutting out


I'll bet you have a poor connection to that speaker, someplace along the line, anywhere from the amp to the raw frame speaker inside the box. Let some music play while you jiggle every connection everywhere. When you can make it stop working at will by jiggling something, you've found your fault.

The only other possibility that springs to mind is a fault inside that channel in the amp.

My pioneer vsx-518 has a noisey cooling fan, is that normal?


Before replacing the fan, check for loose mounting hardware and cracked or damaged blades

I have Wharfdale 4000 Xarus speakers connected to my Pioneer VSX 817, the last 6 months it keeps saying overload when i have the volume further than 40db. Never use to do it... and i have re wired the...


Testing your amp at max with the speakers disconnected will not play a factor because there is no power being drawn so the amp is not being used. Those speakers are rated 90db and really pound but also draw a ton of amps. The key thing here is to keep it cool, cool, cool. Put a fan on it and keep your receiver on a hard surface with nothing stacked on top or anywhere within a foot of it. Keeping it cool will help prevent overloads or (protection mode). Back it down every now and them and give the system a rest for a few minutes. Double check the negative and positive connection on the speakers to the receiver. We all have hooked them up backwards sometime and this will have the effect you are expressing. What is the phase set at on your receiver? Set it down to "0" and go up to where it sounds best without distortion. One more very important thing. What is the Ohm switch on your receiver set at? Put the switch on 8 Ohm even though your running 6 Ohm speakers. That switch only steps down your voltage feed to the power selections which will hamper the overall dynamics and fidelity of your receiver. This switch is really not even necessary. Putting that switch at 8 Ohms will give you more headway and aid in keeping your amp cool.

Cuts off and displays "Protect"


The protect light comes on when the amp cuts off the speakers to protect them from damage if something's wrong in the amp, or to protect the amp from speaker or wiring problems. If the amp plays for a while before cutting off, it's probably a thermal problem in the output stages. One of the output devices may be acting up as it heats up, or it could be bad connections that open up because of the heat. The trouble might also be caused by components in the power supply as well. Without having the unit on the service bench to check it, it's not possible to suggest specific things to look at. The manual wouldn't help you other than to say check your speaker connections and then have it serviced. The best thing to do if you want to keep this is to find a servicer in your area and get an estimate for the repair. Or if you or a friend is technically inclined, look into purchasing a service manual and see if you can do-it-yourself.

When i play music loud the sound cuts out

I was playing guitar through my fender 85 amp and the volume suddenly cut out to almost nothing and I couldn't make it loud again?


The speaker could be blown. Try touching a 9volt battery to the terminals on the speaker. If the speaker makes a popping sound its not blown. The other culprit could be the input jack of the amp. If its soldered directly to the board. The retaining nut may have come loose and the jack wiggle around with the cord tension. resulting in a solder connection breaking at the board. But that usualy will give a ground hum or no sound at all. So im leaning towards a blown speaker. (providing its a solid state amp) If it's a tube amp. it could be that one or more of the power tubes are bad or have a vacuum leak and may need to be replaced. ( you have to replace all the power tubes at the same time and have the amp biased.

This sounds like a power supply problem. The high voltage for the tubes is not right. Either you are missing an amplification stage because this or one of the coupling caps is faulty. I'd have to see the unit itself to give you any more details.

I have a Holden Wasp XL base amp. 100 watt?? Quite old, 70's ish. CAn you tell me how many and what size speakers it will run. Thanks, Lance


hell yer, built in New Zealand... or Aussie, cant remember. Best sort of speaker box for bass is 4 x 10inch quad box. Next. a single 15 inch, or use both together. The head you have I think was more of a PA system than a bass amp, but will certainly do the job. So long as you are not trying to keep up with a Fender twin, or a Marshall stack. 100 watts don't go far for bass. I would go for the single 15 inch driver to more the most air.

Have a Fender Twin 57 custom shop reissue, 18 months old, keeps blowing the mains fuse after approx 30/40 into a gig. Amp not overdriven, no external FX used


Hi debdenplace

Blowing fuses at gigs is not a very nice habit. I suspect that you need to retube the output stage. It is the most common cause of fuse blowing. Even though not being overdriven, the life you get out of output tubes relates to volume and time. The higher the levels, the more often they may need to be replaced. Go for the Groove Tube replacements if you can afford them GT6L6GE , but I use a gain matched pair of Sovtek Russian made Electro Harmonix ELH6L6EH in this type of amp. They cost about half as much, are designed with Fender style output stages in mind and do a great job.

Auto amplifier


It depends on if you want it to be able to play really loud and really clear. The deck will probably drive them pretty good on its own but when you really crank on some head decks the sound can start distortring.
Wheres the sub it the package?
Get a less powerfull, 50 Watt X4, amp and get a decent sub with a mono amp or they have all in one 4.1 channel amps. To drive the whole system and keep it easy.
Have fun
