Your cart is empty.In this article, we deal with a topic that is a common concern among users of car stereos. The amp turns on, but no sound is heard, even on increasing the volume.
Let us begin with this disclaimer. You cannot fix a blown amp unless you have some training in electronics. However, is your amp blown?
Let me share a little anecdote with you. My father was a highly-skilled electrical design engineer. He always used to fix broken appliances at home. Growing up with him, I also became a handyman of sorts. One day, we were looking at a faulty electric iron. On opening it, we could not detect a fault. After a lot of investigation, we discovered that there was just a loose connection in the mains plug. Keeping in mind the above incident, we can say that the same principle applies to several other electric and electronic appliances including amplifiers.Linghem dating sites

Fixing a blown amp channel Discussion in ' Audio Hardware ' started by mindblankingJan 29, Location: Baltimore, MD. Guess what idiot boy did? Touched two speaker wires together and BAM! Anyway, I have a short or blew one channel of my acurus x3 amp.
Anyone know how easy it is to fix a blown channel? Is there another fuse that needs to be replaced? Do I now own a really nice paper weight? Any help greatly appreciated. Location: San Antonio, TX.
Odds are this will not be an easy fix. The fuse blew because something it feeds shorted to ground. Most likely you shorted the output transistors.Missing ohio
I'm not familiar with your amp but besides replacing the output transistors you will need to make sure they didn't pull enough current to damage something in the bias circuit. Time to send this to a qualified tech. WardswebJan 29, Any particular reason you don't want to use the Adcom amp?

If you decide to repair the amplifier and you make mistakes, it could cost more than having the amp repaired by a repair shop.Car audio systems can be tremendously complex, and car audio system problems are often difficult to root out.
In addition to having all the same components of home audio systems, car audio systems are also subjected to temperature extremes, vibrations, and other stresses on the road. So while car audio amplifiers are just one component among many, the problems they can introduce are vast and varied. Some car audio problems that are commonly attributed to amps include sound distortion, no sound at all, and even bizarre sounds like farting.
Some of this can be caused by a broken amp, but all of them can be caused by other underlying issues that will still be around if you try to fix the problem by throwing a new amp at it. In order to turn on, your amp needs to have power at both the remote and power wires, in addition to a good ground.
If the remote turn-on wire doesn't have power, your amp won't turn on. The remote wire acts essentially like your finger flicking a switch, where your finger is battery power, and the switch is a mechanism inside the amplifier. The remote turn-on wire usually comes from the radio, in which case your amplifier won't turn on if the radio isn't on. So if there is no power at the remote terminal on your amplifier, the next step is to check for power at the corresponding wire where it connects to the radio.
If your amp is wired incorrectly, and the remote turn-on is connected instead to the power antenna wire on the head unit, you may find that the amp only powers on sometimes. In this specific situation, the amp will usually only turn on when the head unit audio input is set to AM or FM radio.Msg viewer
The power wire is the next thing to check if you find no problems with the remote wire. This wire will be much thicker than the remote wire, and it should have battery voltage. If it doesn't, you'll want to check for any inline fuses and verify that the wire isn't loose, corroded, or shorted out somewhere. If the remote and power wires both check out okay, the next thing to look for is continuity on the ground wire.
If everything there checks out, then you will have to rule out problems with individual components. The first step in diagnosing an amplifier protect mode light is to simply unplug the speaker wires. If you notice that any of them are blown, then that may be the cause of your problem.how to repair amplifier channel, electronics
If you are unable to find any problems with your speakers, RCA patch cables that are grounded out or otherwise faulty can also cause the protect light to come on. To check this, you can simply hook up a set of good RCA cables to your head unit and amp. If that causes the light to turn off, replacing the RCA cables will fix the problem. In-home audio setups, clipping is typically caused by an underpowered amp or inefficient speakers, but loose or burnt wires can introduce similar problems in cars.
This is a pretty easy process if you have access to both the head unit and the amp — simply unplug the RCA cables from each unit and reconnect them with a good set. Verify that the head unit is turned on, the volume is turned up, and cycle through multiple inputs, like the radio tuner, CD player, or auxiliary input. If you get sound from one input but not another, the problem is in your head unit, and not your amp. If the amp drives that just fine, then you have a problem with your speakers or wiring.
First, you need to inspect your patch cables and speaker wires. If the cables that connect your head unit and amplifier run alongside any power or ground cables at any point, they can pick up interference that you will then hear as distortion.
The same is true of the speaker wires. Using higher quality cables or wires with good shielding can also help. For more information on how to diagnose that type of problem, check out how to deal with ground loopsand more details about what causes car speaker whine.
Strange sounds can come from a subwoofer that's overpowered, underpowered, or simply installed incorrectly, so getting to the bottom of this particular problem can take some work. This can lead to an unfortunate farting sound, as the vibrating speaker cone drives air into and out of the box past the seal. This can be fixed by simply seating the speaker properly.

Aug 27, 14,7, It might well need to have the controls cleaned. If you can get inside you might find a blown fuse. In some amps there are two fuses per channel and if one of the pair blows it will produce distorted sound. If they both blow it produces no sound.Nunes has been an ever-improving champion in this sport and is soaring on a five-fight win streak and is perhaps the deadliest fighter in the game. Latifi is an aggressive knockout artist, who sometimes has the habit of walking straight in to some bad hands and knees.

And what better way to prep for this long-awaited journey than to take a peek at the teams and players oddsmakers believe will have the biggest impact on the impending pro football campaign.
Love them or hate them, the defending champs are the prohibitive favorites to win it all again. The last team to win back-to-back titles was of course these same Patriots, in 2004 and 2005.
As long as Belichick and Brady are co-piloting the ship, New England is going to represent smart money. The pass rush and offensive line depth are concerns, but former AFC East rivals Stephon Gilmore and David Harris will provide solid help on defense. This price might seem like a waste of cash, but the value will never be better. With the Cowboys morphing into a suspension turnstile this summer, the Pack have jumped into the lead to seize the NFC crown. However, it almost seems by default.
The days of the cheeseheads being a sexy pick are over. Not faceplanting in the spotlight is the key. Bottom line: there are more attractive teams with much more value. Similar to Green Bay in that they look the part and are more than capable of playing the part, but something feels askew. Or a questionable secondary that was easily shredded by Brady in the AFC Championship. Joe Haden should make a difference, although the fact that the Browns of all teams dumped him is worrisome.
Not seeing the value here. Even delusional Cowboys fans are beginning to tiptoe off the bandwagon. Multiple players suspended for portions of the season. Young quarterback primed for a sophomore slump.
Recovering from a collapse as monumental as the one Atlanta suffered last February could take years, not months.
