i hate xplod, i had one "xplod" on me. the rca's got fried and it wasnt my fault or the people that installed it, they checked everything. i have the Alpine CDA-7874,, great h/u, especially if u have subs and a main amp(amp for main speakers) really really good headunit. great sound quality,, i havent heard any of the others but the alpine,, man i love it
