just bought a dual dvd player for my 03 dodge truck and it has just one plug for the subwoofer and my amp plug from my other unit has two, so i bought a y connector and hooked it up but it only powers one of my subs and wont power both . i tried it on my two 12s and two 10s and it does the same thing . my 10s and 12s were all working off of two separate amps right before i switched the unit out . any suggestions anyone???? i also am installing the toggle switch today to fix my problem with the brake engaging
