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.
