Running Inline fuse to battery suggested by CRTN can be a solution to the AMP overloading and blowing fuse in the box, this also requires new wirings and you bypass fuse box, therefore can sort out also wiring problems. If not done properly the wiring job can mess up your car and damage more device, the job can be more complicate then you expect, and it is better done by a technician.

Moreover your unit is blowing fuse when you turn on the CD, therefore it is not necessarily a charge load problem, even if this is the most likely eventuality, as when you turn on CD, the power absorbtion from unit, and therefore the load on fuse increases.

Before running a direct inline, check all the wirings, paying particular attention to the connectors at the back of the units.
A lose fibre that is shorting can easily be cause for the problem.

Its definately the connection issue as the circuit is getting over loaded current from its connections.just check out the wires properly either they r connected loose or they r having a small cut in between so its blowing the fuse as the circuit becomes incomplete.in such casses just replace the wires and that will be fine.

Ur facing a shorting out in the board

chek it using multimeter.

then remove it

most likely it would be in the disk player system.

Mostly all amps have a relay against short circuit and all have a fuse on the output stage.But i guess yours is very cheap or very old that would explain for no protection circuit.

But I suggest you first, fit a relay on the just before the output stage on each channel and then replace all the transistors.

What size fuse is it, and is it in the main power line, or on the amplifier?

    Step one : isolate the amplifier



    remove all wires and only attach Pos, Neg, and rem.



    If the fuse blows, the problem is internal and needs to be serviced.

    If the fuse is good... check with a voltmeter set to ohms that the voicecoils register the proper resistance.

    Hook one up... then the other....

    If the amplifier is STILL on without blowing fuse, attach one RCA and then the other (while powered on.)

    A fuse blown here indicates the other end is hitting bare metal. Remove the radio and tape up the used and non-used rca jacks.

    In the above comment i made, it is the speaker's voicecoils you are checking resistance for.

    it would also help to know the components attached to this amplifier... subs, coaxials... factory speakers... etc

    Let me know, and i will help you further.

    The amplifier is seeing something it doesnt like. Most of the time it is a ground thru the power supply. Indicating blown speakers, or bare wires touching metal.

Will the amp blow my speakers?


If you bridge the amp and get 1000 watts RMS and that is split going to two speakers then you will get 500 watts RMS at each speaker. If you have your amplifier on maximum gain it may blow your speakers, not because they are overpowered but because you might run into "clipping" issues running the amp at maximum capacity. Just to be safe I would dial the amp's gain down to 3/4 of the way to full gain. That should give you ample power and keep your amp from clipping and running hot.

I have a 10.2 Orion Hcca subwoofer 4 ohm and wanted to know if I can put each coil to each channel its a Brutus 1200 watt 2 channel amp model 1210d is it safe for my woofer and how much rms wattage I'm...


You would need to know what power your amplifier supplies at 4 ohms. In reality, you would be better off bridging the amplifer and wiring your sub in parallel to a 2 ohm load. This would allow you to pull the most power out of the amplifier. It would be safe to do a voice coil to each channel on a 2 channel amp. However, if you happen to have a 4 voice coil sub and attempted to put two 2 channel amps to it, you would have to make sure your amps are leveled. No easy feat. The variance you could have with that could damage the voice coils. But luckily, that's not your case.

FUSES BLOW WHEN TURNING MUSIC UP


Have you checked the speakers are of the correct impedence, car audio equipment is usually 4 ohm. If the loading is less it can effect the performance of an amplifier which is not designed to operate with loads lower than specified. If the amplifer is being driven too hard this can lead to fuse failure although it will probably be a short some where in the speaker wiring or the voice coil or the speaker is on its way out shorting under high loads again causing fuse failure.
Further more if the amplifier has speaker protection which many modern ones do the trip circuit should switch the speakers off before a fuse blows, it could mean the output stage of the amplifier is faulty which means it can no longer handle full power output causing fuse failure.

Orion xtr15 to a american leagacy la 660 amp


your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.
Positive on sub to Positive on amp.
Negative on sub to Negative on amp.
This is your only possibility.

Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.

How to wire 2 dvc subs to a orion 2150sx ? dont know the wire colors or how to hook um to my amp.


what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??

Orion SX / GS / HCCA amp Wiring guide:

Orange = Right Positive
Black/ Orange = Right Negative
Yellow = Left Positive
Black/ Yellow = Left Negative
Blue = 1+1

Bridging of SX or HCCA Amps:
1. Use the Orange wire for Positive.
2 Use the Black/ Yellow wire for Negative
3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

Finally, take a - from the second woofer to the amplifier -(black/yellow)

Now you have a 4 ohm load on your bridged channels.

My Pioneer GM 5300t amplifier blows fuses all of the time. It says to have two 30 watt fuses in it and thats what i have yet they still keep on blowing. My subwoofer is a Pioneer TS-W302R Twelve-Inch


Do not continue to put new fuses into the amp until you have figured out what is causing the problem. It will only increase the chances of causing more damage to the amplifier. I have been repairing car and home amplifiers for over 18 years and have a lot of experience with Pioneer amplifiers since I work at an authorized Pioneer service center.

This post will be long, but if you bear with me and forgive my long-winded answers you may be able to determain your problem even tho I really don't have enough information to figure it out yet. If not, we can get a little closer with more information.

Does the amplifier blow the fuse as soon as you connect power to it, or as soon as a new fuse is put into the amp? If so, the amplifier has some shorted components in the power supply. They have a bank of mosfet transistors in the power supply that sometimes get shorted when the amp has been pushed beyond it's ability, or just from a random part failure, or if the impedance of the speakers is too low. Your speaker is a 4 ohm speaker, if it is at a lower impedance than 3 ohms when measured with an ohm meter then it will need to be replaced. Even if it still plays, it is too low of a load for the amplifier and will cause more current to go thru the amp than what it was designed for. If you are using more than one speaker and have them bridged it will do the same thing. This amp is rated at 4 ohms bridged and 2 ohms per channel stereo. When you connect 2 speakers together and then bridge them they become a 2 ohm load which causes double the amount of current to flow thru the amp. It was not designed for that. Sometimes you can get these component failures just because there may be a solder joint or two inside the amplifier that is cracked and not making connection very well and this can cause components to short out because they are not operating at the proper voltage.

If your amp blows the fuse only after it has been turned on by your head unit, you will most likely have a blown channel. This would require the replacement of the output transistors of the bad channel as well as a few resistors and sometimes a few other parts.

If your amp will turn on and play for a while and then blow the fuse at higher volume levels or after a long time playing the problem can be either a bad speaker at a lower impedance or one or more components that are breaking down after they get hot or at a certain volume level.

As you can tell by now there are many reasons that an amplifier can blow the fuses, and figuring out just what the cause is can sometimes be a difficult task. It may require that you have a multimeter to do some checks on the amp and a power supply to power the amp on a bench so you can do those tests.

If this information has not helped you to determain the problem, please give me as much information as you can about how you are using the amp. How many speakers, where they are connected, at what point does the amp blow the fuse, and anything else that you can think of that may or may not be important. You never know what might give a better clue, too much information is always better than too little.

Thanks and good luck,

Dave

Have a kenwood kac849 600w amp keep blowing fuse on amp as soon as power is too it power wire got wet and now this can i bypass that fuse some how


It would be very dangerous to bypass a fuse. If it keeps blowing, bypassing the fuse will only create lots of internal damage and maybe a fire as well. The fuse is blowing for a reason, the amplifier is not going to somehow start working because you bypassed the fuse. You also need to stop trying to turn it on, every time it blows the fuse, it keeps stressing the components inside. You have a shorted power supply, probably water damage as well since the power wire got wet.

I repair car amplifiers for a living, and can tell you with all honesty that bypassing the fuse would be a terrible mistake to make, the amplifier would end up being un-fixable with holes burned right into the board.

Please, just take it in for service or get a new amplifier. That is the only sensible thing to do. The amp will not start working bypassing the fuse, it will only start smoking.
