Ok, i have a xplod 1000w amp,with a single kicker cvt 12, and at low, very low volume you hear a low sound of distortion, this a new sub, and the old did not do this, at high volumes,the noise goes away and sounds good, this is only at low sounds, any advice would be appreciated
Give that new sub a chance to "break in". New speakers require a few hours of use before the voice coil(s) and spider break in and began operating at their best performance. Is the box within the operating specs of the sub? Is this a ported box; if so you will here some turbulance type noise from the port. What type of distortion are you hearing? Alternator noise(dentist drill like sound) would only be noticable through a sub at lower volumes due to the frequency response of a sub. Is the amps lowpass crossover turned on?

well start with. turn your hi pass completely off. Turn your bass boost completely off. Turn your input gain copletely down. and turn your cd player to about 3/4 of what you listen to it at. Then turn your input up until it starts to sound a little dirty(distortion) then turn it down a notch. set it at a 80 herz filter so it allows nothing over 80 herz to come through. I just installed one of these jl amps a week ago. 1400.1 and it made two kicker cvt's sound amazing just have to set it just exactly like i told you. it will hit tight as hell and loud and it will hit all frequencies way better.
Subsonic refers to frequencies too low for the human ear to hear. Generally humans can hear frequencies in the range of 20 to 20000 hertz (cycles per second), but we hear best in the range of 1000 to 4000 hertz. High amplitude subsonic frequencies can cause damage to your speakers so many amplifiers have an electronic filter in them to reduce the amplitude of these very low frequency signals.
probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
try running the system with a cross-over configuration.
So your left + will be left + and your right + will be in the right + but put the right (-) where the left (-) is and left (-) where the right (-) is. If that doesnt work, then that means that you shorted out your audio out channels. the only way you can fix that is if you have good soldering skills. But other than that I'de say scrap it, unless you have the high outputs and then buy another amp, some mids and highs and connect the mids and highs to the xplod
Yes. If the rated power is 380W and the Max power is 1000W then it will handle it. Subs fry when clipping occurs. Clipping is when the amplifier is pushed past its capabilities and the output to the sub gets "dirty". The better quality the amp, the safer it will be on your speakers. It is also important to remember that the gain control on the amplifier is NOT a volume control to boot the sound, it is only to match the output from the headunit to the input handling of the amp. Cranking the gain up too much WILL CAUSE CLIPPING.
That's not a 1000w amp. It's a 400 watt amp when loaded to it's lowest rated load. If you have one speaker per channel (the only safe load if you have single 4 ohm coil speakers), you're only getting 165 watts/speaker. It's probably distorted because you're driving it to clipping.
