HI, im new to this site... but i have a question... i have 2 12 inch subs in my maxima... i took the sub out last week and when i put it in, it works but not the same as before. I can barely feel the thump that i used to in my car. I think it could be the frequency... if anyone knows whats wrong please message me... i would greatly appreciate it.... thanks

 

are the subs in a enclosed box?

 

Also is the box ported?

If you port your box you get better sound flow. Also you may not have the wire's connected properly. Give them a fiddle and see how it works.


Also check if all your wires are good. If you have a fault in one of your wires, it may be causing it to short out a little.

Let us know how u go

 

Check your wiring, also check to see if it is sealed right, may have a leak
