My kickers are in a brand new ported box that runs the whole length of my back seat in a chevy full size dually truck. they sound muffled, distorted, and they have a vibration. they sound like ****. we have tried everything. please help if anyone knows a solution
SOURCE: 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.
SOURCE: Need specs to build box for my truck
I do design sub enclosures for a living and I give free specs on basic setups, so you are in luck. As a starting point I'll start by saying that fitting them under the seat may not work that well. Each sub will need about .75 cu.ft. sealed and probably double or triple that for a good ported box. I can get more specific If you e-mail me ([email protected]) the specs on those subs. Specifically I will need the Theile Small parameters ( these numbers-VAS, QES, QMS, FS, etc,) and then I can give you a better idea of where they will fit. If they do go under the seat they will probably not produce really low bass because smaller boxes generally produce higher bass tones. This decision should be based on what you listen too and what you expect them to sound like. They most likely will be more thump than boom and some people like that, so figure that out as well and let me know. Also my father has the same truck and there is a lot of room under the back seat. You can also gain some extra space by using fiberglass to conform the enclosure to the contour of the truck.

SOURCE: What amp need to use for Kicker (2) S12L7 12in Solo Baric
you should use an amp with approx half the power of the speakers max output (i.e 1000 watt speaker use no more than 600 watt amp)
The cutout simensions for the kicker 15" solo baric are 13.75".
SOURCE: Kicker CVR making strange noise
I purchased this kicker saturday. Monday mine made the same weird noise. wednesday i had time to take it back where i got it and they replaced it but as soon as i did it made the same noise. they gave me another one and said if i have problems with it they will replace it. i have a feeling this one will do the same thing. They told me it is a problem with the speaker so maybe try taking it back and telling them what happened and getting a new brand
