ok some 1 told me to get a line driver because my radio has 2 pre-amp outputs that are 2.2volts and im running to sub amps of the sub pre-out and a 4ch from the full range out put, i was told that i will have a huge increase in sound kinda like a bass boost the line driver i wana get is on sale at sounddomain for 120 bucks ots 9.5volts rms but do i really need 1? i mean im runnin the 2sub amps of the 1 sub out put so each amp is only gettin like 1 volt, but my friend hook his radio up to my setup and he has 4.5volt out puts and it slammed the hell out my setup it sound atleast twice as loud and thats with a really shity box that my subs are in well any info you can provide would be great, and another question how good are VENTED BOXES compared to ported i have ported not and each sub is on a 2..0foot box ports are about 14in long and there are 2 ports in each box, i think it sounds like crap all midbass and sometimes i get some nice deep bass hits but that rare and i tried seal and it ****** to so vented is my last hope, the setup im running is:
pioneer premier6400
4 kenwood 5x7s
4ch 360watt kenwood amp
2 12 rf power hx2s {crappy 2.0ported box}
2 1000 interfire class d amps {1050wts rms each}
