I know its an 8in SUB but thats it. Being an 8in the depth will be pretty shallow and the magnet not to big. I am going on experience only. Most factory speakers are pretty weak.
I have seen JVC go so far as to glue an extra donut magnet to the back of a speakers back plate to increase pull on the coil, I am not sure the desired effect of doing this as the power rating would be limited to the wire and coil not magnet size. Maybe they were limiting coil travel. But that cheap trick added 3/4 of an inch of mounting depth.
Those are supposedly Rockford but I imagine bottom bargain basement in quality. If that is the case I am surprised Rockford stooped so low. If I am wrong please feel free to correct me. I have the Rockford and if it is good, good to know! :yes:
