So I'm getting subs put in my 01 bonneville SE and I'm not too sure about what subs I am gonna use to be loudest. I am going to have a band pass box built to the exact specs of the subs I decide to get and it will port through the arm rest hole from the trunk to the cab. I am going to run a pdx-m12 alpine amplifier and a cda-117 alpine head unit. The subs I am leaning towards are the p3d2-12 inchers. Any advice for better subs or if I just shouldn't use fosgates in general? Thanks a lot for any help.
