i have two sr124dvc on two jl 500/1. on some songs the sub vibrates brrrrrrrrrrrrrrrr for a long time
on other songs it does boom boom like i guess it's suppose to. they are on two sealed enclosures the size polk recomends on their site. Another thing is, i don't feel it hard as 400$ subs shoould. i seen ppl with way cheaper stuff and it's very loud. should i replace my amps..
one last questions how should the subs be facing for optimal sound. UP, towards the front of the car, towards the back, towards each other, or towards the side of the car.
also i have sr6500 in the front, what should be the cutoff for the speakers and the subs.. thx
