Hello. I have a Hybrid SE with the stock 6-speaker sound system. I've been reading up on a few forum posts about adding new/better speakers to the standard set. I've come across posts not recommending any non-stock speakers with the active noise cancellation system as it would distort the sound. If that's the case, what speakers are installed in the Titanium hybrid and how does that configuration work? Also, how can I get my hands on the factory speakers originally installed in the Titanium? Thanks.
