View Full Version : amp problem
06-16-2004, 06:18 PM
well. i am hoping you guys might know.
every time i am driving the car, my amp keeps cutting out.
in my attempt to figure it out, i noticed that if i shake the car the amp cuts out. - i have tried to check all the wires by shaking any visable ones & nothing happens.
the amp still has power, but the "power" light dims slightly.

Sounds like a bad or weak ground. Try relocating the ground wire to a new bolt. Make sure the bolt has a good, clean, paint free contact to the body of the car. Depending where the positive cable is wired, that too could have a poor contact. If it's connected directly to the battery check the connection, either it's loose or the wire has a break.
While my guitar gently weeps.

also could be a mild short from the insulation rubbing away from a wire.
usually it will burn out the fuse, but ive seen a mild short that had similar problems.

sometime im going to redo everything at the same time, so i know its perfect

i've had this happen to me with the RCA jacks....... the outer gold ground wore off of the pc board inside... so i just welded it back on... and it works like new...... i know its more possible that its the ground because of the power lacking of the led.... but its just something else to look at if there is nowhere else to turn.

Well I think everyone else covered it.
1. Bad ground
2. Bad fuse
what amp? watts? power wire size? ground wire size?
also a fuse may look good but be shot. Try replacing the fuse.
any questions feel free to ask

amp: JL e1200 mono block (200w)
8g power & ground

What kind of fuse and where is it located? How many amps is the fuse rated for?
8 ga is fine for 200 watts.

i dont know, its the one that came with the monster cable 200w amp kit

i changed the rca's & relocated the ground (& removing some paint)
now when i am on the gas (speeding up & in gear) the audio cuts out, but if i hold the rpms it will start playing again.
when i was running the amp wire & came short & used a cheap dis. block 8ga. to 8ga. do you think that could reduce the power to much?
or could it be my battery or alternator?

1. where did you hook your main 12v power line to?....
2. The remote wire ... is it a clean hook up to the Ign. wire on the back of your cd player?
3. Did the RCA's come with your monster cable kit?... what gauge?

1 - battery
2 - does have a split, but is a good connection
3 - new 401 xln's (i even covered them in plastic, just to make sure)

hmm... sounds like its not out side the amp... but it still is possible..... have you opened the amp itself up yet?.... make sure there is nothing burned on the IC boards or and y loose or broken solder. It is possible that it could be an interernal componenet (capacitor for example that could be worn out .... since your led on the side seems like it's either not able to get a charge from an outside source or be able to hold it from an inside source)

today was strange tho... it started to as i left the driveway but it only happen one other time today...
