Where is a good place to mount my passive crossovers? They are not really big ( JBL MS6C ) but I don't want to mount them in the doors. The owner's manual says not to and I don't want to risk it besides I'm not sure they will fit anyway. I'm thinking putting them under the seats. Left xo under driver side seat and right xo under passenger seat. Is that a good location? I also need easy access to them because they have 3 selectable tweeter attenuation setting levels which I may need to get to at anytime.
