the orion hcca 10.2 is 1500 rms 3000 peak (underrated) and the re mx 12.2 is the same, im also building my own truck box for back seat in kingcab going to be a centerconsole in middle and goin down to the floor going to put sub there, but i could manage a 12 if yall think it would be better for the money cuz the re mx 12.2 is 30 dollars cheaper and the specs are just hair line different me personally i think i should get the orion......so let me know something soon guys thanks
