I've given a lot of thought as to how I'm going to tackle the (lack of) bass issue in my MS3 and I'm leaning more towards removing the spare tire (who needs it anyway?) and utilizing that space. I haven't yet looked but was wondering if anyone has been able to (or thinks it's possible) to put a powered sub (like the Infinity Basslink) in that space. It's tough to tell looking at the pictures online... and I haven't even checked out my spare tire well... but I'm thinking it's not doable. probably not deep enough. If anyone has any options or ideas please let me know. I like the idea of an all in one... trying to keep the hatch functionality in tact.
