I have 4 amps and an electronic crossover in my truck, and I'm trying to figure out how I can use the aux_sw pin of the DSATX without exceeding it's current limits. I was originally planning on just using a bosch relay, but have since discovered that it's not capable of driving it. Is there any way to daisy chain relays where I have a the DSATX ground trigger a small relay that in turn +12v triggers a larger relay grounded directly to my vehicle's chassis?
No announcement yet.
How can I control 4 amps & a crossover from DSATX?
