hooked up my ds693's today (rear fill). running off a kicker kx350.4. started the engine, and yeah, there it was. revs with the engine, when my rockford p1653's in the front also running off the amp are un-effected. even with only the fronts running, no problem. earths on amp and HU are seperate with good contact points, but, as i read before, i had the rca's, remote and power leads running together. but it didnt effect the rockfords as i ran this for a week. i'll seperate the rca's from the power, but if this doesnt resolve the issue, what do?
