power cables running to it are fine

still connected to the engine

yesterday, it was working, today it's not

am I safe in assuming it's just a blown fuse?

check the fuse on the side of the amp,
then the one on the power wire running to the amp,

if those are good, make sure the turn on lead for the amp is working properly, check this with a voltmeter/ohmmeter

if that doesnt work, you amp is DOA I guess

check that the power line has 12+V to ground (volt meter)
use a short piece of wire (16G would be plenty). use it to connect the batt terminal to the remote terminal. if the amp turn on, the problem is in your remote wire or your head unit. if it doesn't turn on, something is wrong with the amp.

and make sure u have a clean ground....and that there's no paint in there.

alright, so I found what I thought was the problem. The 40amp fuse running from the engine was blown. I replaced it, and it blew again immediately. So I guess there's a short somewhere either in the amp, or the wiring. The amp isn't more than a couple of years old, so I don't think that it. Any ideas on how to find where the short is?

well make sure its a short first
take out the fuse and check for resistance between the power line from the battery and ground
if its infinite then its your amp, if zero then trace through your power line and find the short

a couple of years is plenty of time to kill an amp, especially if you are pushing it hard

guess i need a multimeter then

especially if it's a Mexi-Bass Supreme 900 Watt (.5 Watt RMS) that's been... well, turned on.

8/3/2005 6:46:37 PM

it's a kenwood 800w

haha

on point

^yeah just check the resistance first

word, thanks

oh yeah, i don't know if this helps or not, but when I put the new fuse in, i heard a few thumps from the subs when I first turned the car on. then the fuse was gone. thumps as in what huge speakers would sound like when first cutting on, a deep bass crackling

my money is on it being the amp

8/3/2005 6:56:41 PM

drats

8/3/2005 6:58:28 PM

you were right. it was the amp

8/6/2005 5:55:45 PM

Just for future reference

I wouldn't use this method for checking for a short because you are not suppose to check resistance when there is voltage on the line(because the voltmeter could easily get fried)

so if you would like to use this method then take the power line loose from the battery then check the resistance from the wire to ground to see if it shorts.
