Hi all maybe a strange question , myself and the misses are a duo me on guitar and wife singing , we have recently bought some active 15" EV speakers which sound pretty good on there own but a whole lot better with a sub . My question is our 15 inch sub is just a little too big in depth to fit in our car so do you think it would be ok to trim it down a bit by maybe 4 inches in depth so it could then fit in our car ? would it alter the sound of the sub a lot ? I hope this makes sense .
Perhaps this will work, it's something no one else suggested...
Put the original cab in storage for resale purposes as suggested.
Build the new cabinet, and instead of the same depth, build the new cabinet to different HxWxD ratios to the depth and make it slightly wider and/or higher, keeping the cabinet's internal volume the same.
