I'm debating on stereo in my 900xp, and looking at the infinity aftermarket that will fit in stock dash. Thinking of using the under dash stock pods as well, but would rather not run an amp. Does anyone have this setup with no amp? Looking at using radio while riding on road, as well as let it play while I load firewood. Just wondering if be loud enough while driving to hear it, or if I would have to add an amp, rather keep volt usage down if I can. Thanks
