I have 2 kicker 15" compvr's i have a brand new lanzar amp its a 2400w amp and the speakers a 1000w a piece. i never really turned it up the whole way or overloaded the sub's but the one has a harder knocking sound at the peak of a bass hit i dont know what to do i thinks its either the one speaker is not hitting as hard or the other one is about to blow please help idk what ot do

Re: Knocking noise with my kicker compvr 15"
Comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.

If it's only your subwoofers cutting out and your speakers are still playing and all, try turning gain down on sub amp and see if that fixes it. I know if I crank my amp too high it kicks itself off to try to keep itself from blowing.
The problem is probably the way you have them wired, but could be a couple of things.
A few things to think about.
1. Is your amplifier one or 2 channel. If it's one channel, it must be 2 ohm stable.
2. Are the gains on your amp turned up. This is the little knob next to the RCA input.
3. If your sub is a dual 4 ohm voice coil, you need to wire it to a 2 ohm load. Make sure the positive of the source is wired to the positive of both voice coils and the negative of the source is wired to the negative of both voice coils. This is what is called a parallel set up. If you wired from the source to one voice coil and daisy chained to the next, you probably have it in series, which creates a 8 ohm load. Which mean more resistance, less efficiency, and less sound.
4. Make sure the power wire to your amp is appropriate. A 50-65 amp load up to 22 feet in distance is good for a 4 guage wire. Anything bigger than that will need 0 guage.
5. Make sure your ground is good. If you know how to use a multimeter, check it. Always use the same guage wire as the power wire.
if the unit completely stopped working try connecting the speaker to the working speakers connection, if it still doesnt work then you have seized the speaker, basically the driver is shot and the speaker is dead. you might have a warranty but usually you can smell the burnt coil. turn down the gain and the frequency on your amp as it is not properly tuned and will cause dame like this as well. if you are not certin take the car to a install shop and have them tune and balance you system for you.
1 OHM...ONE... sheesh now thats a low resistance for anything... If they are only 500 watts and they are in parallel, series well NO.. your amp puts out wayyyy too much for those speakers.. 1200w versus 500 watts by 2... srill NOT enough "Head room" for it to be safe... about half is all you could expect before Pop.. sound is heard.
CVR series do not have large power handling capabilities. Your subs will melt before the amplifier is used to its full potential. If the subs arent in a ported enclosure - do that. They both handle 500w rms - so the pr1000 is perfect. bass response is all in the enclosure!
