Hey this has been hapening for a while now iv just beed to bussy to work on it till now but i got 2 alpine type s 12" subs getting power from a Alpine V12 monoblock amp with 600rms and for a while now the subs dont work at low volume but if i turn the bass boost up or the volume up they work fine. im hoping its just the subs so i can get new ones but im not sure because they both dont work at the same time and then they do, its so wired. any sugestions?

 

check your wiring makes sure eyerything is wired corectly

 

make sure all the conections are good and not loose.

 

do u have stock deck or aftermarket? did they used to work fine before at low volumes?

 

this could be an impedence matching issue between the subs and the amp. Which subs are they and how are they wires?
