SOURCE: fuse blows

Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

SOURCE: Subwoofer

Repeated fuse blowing generally indicates a blown power supply, or blown output stages or both. One thing to do is be sure that you have replaced the fuse with the correct type. A T stamped into the metal of the fuse near the rating, indicates sloblo or Time Lag fuse. A fast blo fuse, may work once, or more times, but will never replace a sloblo fuse in this type if unit. Good Luck, hope this info helps, don't hesitate to hit me back here for more help :)

This problem can also be caused by bad caps. This seems to be a real problem with this unit but considering the age I would replace the caps.

Sounds like blown subs, in the process of completely dying out, or a loose wire, possibly inside the box or from the box to the amp. Have your subs tested at a sound shop, or using a multi-meter, check for resistance across the sub terminals. An open line indicates a blown sub.

Amp bass cuts out cuts back on


its a pretty simple principle...combine 2 speakers, and the ohm load gets cut in half. wire them in a series, and the ohm load doubles. for example, you have 2 subs that are 4 ohms a piece. if you combine both + and both - and put them to the amp, it cucts the load in half bringing it to 2 ohms. or, if you connect 1 + to the other speakers =, then run the remaining pair of wires to the amp, that doubles the load to 8 ohms. youll have to "double-ohm" it for dual voice coil subs. on each sub, you can do the same thing. either combine both + and both = into 1 wire to cut the rated load in half, or wire them in a series to double the load by connecting a + to the other coils =, and using the 2 remaining wires. once you have each sub wired the way you want it, then you can use the same rules when connecting multiple subs, by wiring in a series or parallel. it sounds confusing and its hard for me to put into works, but once you do it a few times its really easy. just remember the 1 rule...wire 2 coils parallel to cut the coils load in half, and wire it in a series to double it. hope it helps.

I have an alpine mrd-m1001 getting curr message ho do you reset the amp


Hello deeprajm,

Shorted or low impedance outputs can cause the "CUR" display. Power down everything and remove the speaker wires. If it will then power up without the display, the problem is probably a short in the speaker wire or voice coil, or the impedance load is too low. If there are multiple subs, reconnect them one at a time to isolate the bad one and then correct the problem. If the amp works properly with either of the subs but not both, rewire the subs for a higher final impedance.

If the amp still displays "CUR" with the speakers disconnected, there's most likely an internal fault that requires component level repair.

Hope this helps.

Sony xplod amp(XM-1652Z ) power/protect light


if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.

Nothing working! please help!


no it doesnt HAVE to be wired in it just lets you control the amount of output from the sub. however the spark could have blown out the internal workings of the amp. there are genereally multiple fuses on car amps. have you checked these? if they are blown replace and reinstall if not then it very would could be that the spark caused the amp to fry.

Kickers dont beat like they should


try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..

Subs dont beat like they should


you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.

It doesn't sound like the wiring from amp to sub is your problem.

Is your amp getting a power light ?
Are you sure your remote wire is hooked up properly ?
Check both ends of your RCA cables

Amp cuts off


You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.
