excessive current registered on amp

[adcjones]

ello all.

I drive an 03 cavalier with many upgrades, one of which is an alpine amp and 2 10" kenwood subs. i have had this system for about 2 1/2 years and had no problems with it until now.

this may be due to the fact that i have wired up some other electronic items into the same line as the power to my amp.

driving home one night my subs just stopped working... it was very hot outside and i figured that the amp may have gotten too hot and self-shut down. the next morning i started my car and the amp worked fine. late rthat day, with the volume not up and normal, my amp shut down again... it wasn't hot out this time, though.

So i checked my ground connections and all was ok. the power was hooked up and the amp was on, but the subs weren't doing anything.

the display of my amp reads: CURR.

i checked what this means and it says this:

the amp has been shutdown due to excessive current.
find and eliminate the cause of the excessive current, then turn the power off then back on from the remote control unit.

ok, the excessive current makes sense since i have recently rewired some things, including fog lights and nitrous. i took off all the wires from my battery except for the power line for the amp. i reconnected all the other wires from my amp to my subs and upon starting the amp back up by turning on the ignition it will make a sound like it wants to play the music but then immeadiately shuts off and gives the error message CURR...

I am not sure how there is any excessive current now since the only line to my battery is the power for the amp itself.

anyone else have this problem or have any suggestions? Posts: 4 | From: INDIANA | Registered: Aug 2006 | IP: Logged | Thumper26

My assumption was that the input gains were too high. I never had a problem out of it after that.

But the wierd thing is the amp still says excessive current. I am not sure if I have to reset the amp somehow or if that is possible or how to do so...

does anyone know if the remote line from my amp to my head unit could be the cause? could this be fried instead of my amp? i hesitate to remove the dash in order to check Posts: 4 | From: INDIANA | Registered: Aug 2006 | IP: Logged | SQster

If your sub is completely disconnected from the amp, does it still error out?

[PaulD]

I think sr20 is on the right track, sounds like one or both of the subs are blown or the amp has been damaged.

+1 and if the current was to much shouldn't the fuse on the amp blew?

not necessarily

Normally those fuses will just blow if there's a problem with the amp itself which causes a large draw from the car's electrical system. In this case, I believe the "over current" is on the output side, not the input, and is due to either a problem with the amp's output stage or the sub.

[adcjones]

if the amo has registered excessive current, this means that too much electricity has gotten into it and fried it, correct?

but if this is so, than wouldnt my fuse on the power cord from my batt to my amp be blown?

[PaulD]

read sr20's post, he is saying the overcurrent problem is being caused by the speakers being shorted or just having too low of an impedance. This is most likely the case. The fuse blows when the draw on the power input side to the amp is bad or shorted.

I am not sure how the speakers are blown. they were not being used on high volume when they stopped working... I am not sure what low impedence means...

So this means my amp may be ok but the subs are blown?

[PlayStation3]

impence is the ohm load like if you had them wired at 1 ohm with only a 2 ohm stable amp them the amp would die. also having a short in a speaker does not mean that it is blown blown is when there is infinite ohms so everything stops.

[adcjones]

i am at a loss for what to do now...it seems like my amp may be working but the subs are blown then? i would imagine there is no remedy for this except to get new subs...

would there be any indication of subs being blown besides the reading on the amp? for instance, when i press the actual sub in and out, would it make a sratchy noise or not move at all?

thanks

[PlayStation3]

there is a test actully you have to rip off a lamps power cord and crimp connect the ends to the sub and plug it into the wall outlet then if you hear a noise then it is fine and if you see there is smoke then you need a new sub.

if the amp still errors out, then the amp is the problem
if the amp seems fine, then use a DMM to test the resistance of the sub

[adcjones]

Ok I did some checking and the right sub makes a sandy noise when pressed while the left sub does not. my amp works fine when i disconnect the subs from the amp and it says no error. when i hook up the left sub is still has no error but it wont play. i take it in order for the subs to hit, both subs must be hooked up into the amp? i tried to hook only the left sub up but i am wondering if i have to disconnect the right sub from the left sub inside my box...? when i hook up the right sub to the amp it then reads high current...this means the right sub is not working and blown correct?

is there a way to get just the left sub working? like i mentioned, do is the right and left subs connected inside my box? i thought i would ask before delving in to the box since i have never done it before. surely i can use just one sub with my amp...
