ok then i will do so....
are the amperage of the fuses shown in the diagramm ok?
should i use biger or smaller between the bateries?

why should i do this for????
i was planing to use a 300Amp relay between the 2 bateries, so that no power is going from one baterie to the other when the engine is off...
like the one on the pic

or with odr, wich one you find better?

with .5 farad cap for the zr120

or with the KQ30.........

but i think that with the KQ30 i can only ran one amp..!
you say i should use it for the zr120 and don't use the passive crossover?

with diagrams and caps..
or is there any active crossover that can cut for the ph35 from 8khz?
