Hey I have 2 Comp Vr 12 in a box with a kicker sx 500.2 amp pushing them, the problem is when I turn the bass up and the volume on the head unit is all the way down there is a bad noise that comes from the subs, kinda like a hum or something. All of the equipment is new. Any help would be great. Thanks

turn down the gain and the preout in the head if it supports it. also turn down the frequencey to 80. also dont over shoot the speaker by turrning up the bass on the head unit and then turning up the volume.
For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. If it is a 12 inch sub the box size will be 13 inches x 13 inches x 13 inches. Hope this helps
If they are single voice coil and are 4 ohm you can bridge your amp and run both speakers off of it so your amp sees a 2 ohm load....better bass that will hit harder....(series wiring) look it up on google....
1. Check Grounding system (Player and Power Amp). 2. Ensure your RCA cable is OK 3. You might adjust volume or bass volume on power amp to maximum, just set all to 50% while you are tuning. 4. Check the speaker out cables might contact the ground/ chassis
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.
get a 2 channel with as much watts as you can affored. you wont blow them its better to have to many watts then not enought the subs work harrded with less watts i know that sounds crazy but trust me je
turn them off and carefully push in on the cone (gently) and listen for scratching or scraping- push strait in and they should flow freely in and out if they DO without feeling or hearing scraping the subs are probably ok, next its either the amp is not powerful enough or the box is not soundly built, by that i mean its too small for the subs- is the box ported or sealed? if ported try plugging off the vent temporarily and see if bass increases if it does i would permanently seal the box
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.
