Delivery by jet boat. Excellent installation package, good quality. All marked, very new to setup. But not 500 watts. Maybe maybe 200. I use an equalizer and volume booster app for bluetooth that helps improve sound quality and volume. The speakers are caved into huge cavities in the case (5.5 inch holes) so a lot of bumps come out of the speakers, they just really lack volume. Bluetooth is good for 11 feet. For what I need it for (music doesn't go flat). it works.
