Problems with my new car amp? Is it a blown fuse?

Question

So today I bought a 1100 watt 10" sub, and a 1000 watt amp. I finally got the system installed and working. I had it on the lowest gain so I wasn't getting much bass so I went to turn it up and I must have done it too quickly because the bass got extremely strong then instantly stopped, and now It won't work anymore. I would guess that the problem is a blown fuse but both of the fuses on the amp look fine. Is it possible that I blew a fuse inside the car? Or do you know of any other solutions to fix it?

Answer 1

to find the problem, several information is missing, but let me try to help u out a bit.

first, check if the amplifier turns on.

-if it turns on, then the fuse upfront is ok.

-if it turns on but in thermal-protect mode, then the fuses on the amplifier itself might had been blown. Simlpy pull the fuses out, and check them for any damage.

if the amplifier turns on in Thermal-protect and all fuses are good, then check the settings on the amplifier. never have any setting at Max. this will give a very distorted signal to the subwoofer and will give you problems.

other things to check out

-make sure the subwoofer's coils are not blown. a simple way is pushing down on the cone. if its hard to push down or theres a "scratchy" feel while pushign it down... the subwoofer is likely to be blown. but if its smooth, the it should be good.

-check the final ohm load. by this, check what ohms each coils is.. and how you wired them. this is important because wiring a subwoofers coils diferently, will change the final ohm load the amplifier sees. if the amp is not stable under that load, it will cause problems.

so make sure the amp does not over-power the subwoofer under the final ohm load, and that its stable.

okay check to see if the fuse by your battery is blown. if not then when you turn your car on check if the amp is on.(ex. light or something) if it is and your fuses are good plug another speaker into it. if that speaker plays(with the gain as low as possible) then you blew your speaker. check for a burnt smell from it. also it couldnt handle 1100. it seems like a sub that handles 250. give us some specs and we can help u better

Answer 3

If the amp is under-warranty, send it back.

If not, you might try pulling off the front cover. BE VERY CAREFUL NOT TO TOUCH THE COMPONENTS INSIDE!!! but take a look around inside.  If you notice a lot of black dust or any components that appear to be burnt, then you've fried your amp.

**Note: This should only be done as a last ditch effort, you might want to swing by an audio shop and see if you can have one of the installers can take a look.  I believe places like bestbuy and circuit only charge like $20 for a quick look.

Answer 4

check the fuse in the power line that u have it hooked to

Answer 5

There should be a accessory fuse in your box you might have blown if not chech the inline fuse usually by the battery or on the amp itself.
