i hooked up the sd16k soundigital and there was terrible feedback and engine whine when the mids and subs are all on.
now when the mids amps are disconnected and only the 16k hooked up there is no feed back and works.
when the sd16k is disconnect the mids and tweets sound fine.
i have a kenwood head unit that i think is the problem. but i have to find the ground loop problem first before i install and leave that big amp in.
and i layed half way into my bass knob and that amp is freakish loud. kinda surprized me!
