Review: antes de la compra tenia mis dudas pero ya instalado créanme que se escucha fuerte a comparación del video. están conectadas 4 bocinas de torres y 1 subwoofer de 8 pulgadas todo de uso marino y quede sorprendido de su potencia, no se calienta y no deja de funcionar. estoy pensando conectar 2 bocinas mas tipo torres, esto esta instalado en tubular (buggy) y sin problema hasta el momento lo único malo que al conectarse al bluetooth esto suena a todo volumen y no hay manera de regularlo. muy contento y satisfecho con la compra SUPER RECOMENDADO......
Review: Its only been a few days but its a solid AMP, for this rockville amp you will need to buy a wiring kit from their website or search it on desertcart. Pretty easy to wire just time consuming, make sure you follow the limited instructions and it should work. Another thing to note is that the dials such as gain and the other dials are all set at 0 when you first get it, so don't be confused if there is no sound coming from them, you need to turn the gain up in order for sound to come out, but don't turn the gain to max or you will ruin the speakers. Before you buy an amp make sure you calculate how much power you will need from it by checking the total power of all the speakers. Comes with a mic too but not really practical because my amp is mounted in the back of my boat so id have to extend all 3 wires in the mic to get it to the front but I don't care enough to do that. Ive seen reviews that the wiring kit I used isn't very good, im not sure myself but just make sure you use the recommended wire kit, and Amplfier for the speakers you buy/ install. This review is just everything I struggled with and want you to know so that you can do better than I did.
