Hey fam. I need advice on my stereo setup. I got a custom box made today and when I got it back the box wouldnt go past the factory sub. The installer told me that when he installs the system he is going to take out the factory sub and the box will fit securely. when I asked him if he was going to put the sub back in he said no because the sub would interfer with the sound quality of the new sub that was going in!? Is that right? I asked him if he could make the box lower to make it past the factory sub and he said no because of the specs on the new sub. Has anyone else had this problem? Im up for suggestions.
