Recently I've noticed a noise coming from my amplifier. I have a Kicker subwoofer and an EL CAPITAN Rocky series amp in my trunk and I'm pretty sure the noise is coming from my amp. It sounds like a hissing noise...is this normal? I've never noticed the sound until I recently had my alarm installed. Could something have gone wrong?

the amp itself hissing? or a hissing from the speakers?

Yeah, it's the amp itself that's hissing, not the speakers.

that's a bad thing, there's a loose solder connection inside, or a snake

Any way to fix it? Loose solder connection inside where? And what's a snake?

Pull the amp, it's on it's way to 12 volt hell! Send it back to the manufacturer for repair... Look out for the snake!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Again, what's a snake? If I kept the amp on, will it mess up my system/car? I can't pull the amp because my sub is connected to it for power. Ugh! It's too old to send back for repair too.....

snake you know slithering reptile that hisses, you may be able to have it repaired but the cost may be more than a new amp (unless your handy with a schematic and solder)

Could be the power supply as well. The RF bd amps from 2 years ago had a problem where the power supplies whined on them right outta the box, gotta love the RF quality control. Geese hiss to but its doubtful one could live inside your amp due to the snake already being there.

Well, I believe that the amp is drawing the power directly from the battery. So should I rewire the power line? And about that whole snake deal, I thought a "snake" was a term for something else...not the snake snake. LOL Oh yeah, one thing is that after about 5 minutes of hissing/ringing (it may just be my ears ringing) it stops. I don't know is that means anything!?!

The power suplly is a piece inside the amp so rewiring would not help. I would suggest getting a diagnostic done by an authorized repair depot, may cost you 50 bucks but if the hiss bothers you thats probally whats gotta be done to find out the exact problem.

Okay, so today I was messing around with my amp and so forth and I realized that when my music is on, there's nothing coming out of my amp. Dumb question but umm....music is supposed to come out of the amp right? So then I go and check my subwoofer and I can BARELY hear anything coming out of that. You guys have any idea what's going on? Is my amp broken? How about my sub? :(

put a test speaker on the amp see if you get sound, if you have access to another amp substitute that (eliminate any other things) it still sounds like the amp is on it's last leg

It sure does sound like the amp needs to go to the old amplifiers home in the sky. Music is not produced my the amplifier, an amp should make no noise at all. Use a test speaker like was suggested above. If this speaker does not work, then it's time to find a new amplifier. Snakes, haha, right out of my book.... ------------- Top Secret, I can tell you but then my wife will kill me.

Test speaker? I don't have one of those.... Where do I get one? Also, how would I hook it up to the amp? Okay, there's 2 buttons: a red one and a green one. The green one says protection and the red one says power level low input. The red button is on...does that mean anything? A lot of people that I've spoken with said that they think that the wiring is super bad and that I should try to rewire the power cable. As my friend said, the people who installed it did a sh*tty job. LOL What do you guys think?

a test speaker is a speaker you kno that works (any speaker) and you can hoook up to the amp output for a very short amount of time to see if the amp works and is up to par.
