I've got a Cardo Systems G9 and speakers in my Shark helmet, works well for talking but with music, I can hardly make out the tune, it sounds so bad. But as I say, the system on the 1200LT rocked! Still, you're probably right-- cheapest bet is to upgrade the helmet speakers (and get a quieter helmet-- those Shark EVO line are noisy).
