Start with a good multi output receiver and the work arounds will cease.
Kenwood Excelon DDX9907XR or something similar.
Otherwise go to a reputable audio dealer.
CAR Amp high output to speakers alsop need RCA for a sub
High, I am using an amp and it has front and rear . I am using the rear high output into low low level converter to put RCA to a sub. I now want to use the rear to power speakers, but I will need to RCS to the amp, or ligh level to amp.
can I split off the high level to speakers and still use the low level converter without changing the ohm?
Will I berak anything? is there a way I should do it? do I have to buy something?
