confusion with my amp
im running a pyramid crystal series 1000w amp thats pumping 2 10" 1200w sony
xplods. the amp turns on and it says its working, but i get a high pitch hiss and the amp seems to be doing nothing, although it turns on. im using either 6 or 8 gauge wire from the battery and as the ground and im using 16 gauge wire from the subs to the amp and 18 gauge REM cable. can someone please inform me on what could be the problem, im only 17 and im not too experience with this kind of thing. the headunit im using is a JVC KD series that is 45x4. -- Message posted via CarKB.com http://www.carkb.com/Uwe/Forums.aspx/car-audio/200611/1 |

Did it once work?? Make sure you connection from the Head Unit are OK. It likely there is something not configured or set in the head unit. greg |

You generally want to make the power and ground wires the same gauge. The remote turn on wire can be small. can someone please inform me on what could be the problem, im only 17 and im not too experience with this kind of thing. the headunit im using is a JVC KD series that is 45x4. Is the gain on the amp turned all the way up? This is probably the hiss you're hearing. It's probably amplifying the noise. It sounds like you're not getting signal from the head unit to the amp. I used to have this portable boom box with RCA inputs on the back. As a test, I used to take it out to the car and plug the RCAs for the amp inputs into the back of this boombox. If I got audio, I knew they were ok. brian |

For the head unit outputs, do what I suggested already. For the amp inputs, you would need to find a signal source to plug in that's not your head unit. If you have a wire lying around that goes from a headphone type connector to RCA cables, you could plug an ipod or something like it staight into the amp. If you hear the ipod music, then you know it's either the head unit or the wire between them. Just start eliminating causes of the problem until you're left with the bad item. brian |

If your head unit is outputing only bass signal and your amp has a built-in crossover, and that crossover is configured wrong, you'll end up with no sound, or at least very quiet sound. brian |

I'd take them somewhere and have them tested just to verify that they're bad. Have a look at somewhere like sounddomain.com and see what's on sale. iirc, you have a fairly high power amp. You should really match the rms power rating of the subs to the amp. If you can't afford the high power subs, you can attach weaker subs to the amp you have, but you have to back the gain off or you'll blow these also. If you're worried about how loud they'll get, I'm running two 10s at 100amps (rms) a piece and it's enough to vibrate the rear view mirror and my hair. brian |
