well, he did buy audiobahn.....

 

^^^True statement. Either way, it would occur to me as common sense to find a model # of some sort and research.

 

in an audio setup, you choose your a SVC or DVC depending on the amp you are pairing the sub too. always use both coils on a dvc, if you only use one it will only receive half the power to the sub and it throws off all teile-small parameters when matching the sub to the proper encloser.

if your audiobahn subs are matched right for your amp then try this...check your ground from your capacitor/amp to ensure it isnt loose at the frame where it is bolted to the chassis and the paint is removed to bare metal. also the ground wire should be 4 ga. or larger if your power wire is 4ga.

also use a meter to test each sub for its proper impedance to ensure they are not blown, causing the amp to overheat.

 

Where do you have the Gain on the Amp set? this could be the issue as well.
