Yep, the ol' SWR Wkmn's 4x10 doesn't fit in the Corolla and I'm thinking of using a pair of Wkmn's 2x10's instead. Wanted to see if anybody has done that sort of a swap with success or failure. Mostly asking for feedback because I wouldn't know how this change would work out until after I got it and did battle with my two guitar heros at a gig. Still using an SM-400 to drive the cabs, but may up the wattage, too. Thanks for any thoughts, etc.
