I have had a dual 12" Kicker CVR setup for about 8 or so month now and for the past month they haven't been as loud as they used to? Even in the middle of a song I can hear and feel the bass fluctuating when it should be sounding the same.

Is this a problem with my battery or amp or alternator or something else?

Thanks

 

Could be any of the above, or a combination.

What is the model number of the sub and the make and model of the amp driving the sub?

What kind of box and what volume, [size of box] is the sub in and where did you get it?

Also, what kind of music do you listen to and how loud?94

 

I'm running dual 12" Kicker CVRs in its ported factory box with a 500W RMS Kenwood amp.

I listen to everything from hip hop to metal to rock to techno. I try to keep the volume under 80% to maintain a decent lifespan on the speakers and not blow anything.

The cars a 96 Accord with stock alternator. Batteries a year and a half old. Would a new battery + a sub $80 cap do anything?

Thanks
