I'm using the stock HU so my DSP gets turned on by a switched 12v circuit in the interior fuse panel.The slot was empty and I added the circuit.The DSP then turns on 2 amps and I now want to add 2 fans to cool the amps.Can the switched circuit handle 2 more loads like that or should I use a relay?I'm not sure how many amps the fuse panel circuit can handle so thats why I'm asking.Thanks!

What car/HU/DSP are we talking about? What are the specs on the fans?

Just using common sense would tell me that I could easily use the circuit from the fuse panel because the other fuses in the same column are 20A and 10A. The 5 components I'll be powering probably won't even amount to 1A of draw. Is my thinking correct here?Approval from an expert here would be appreciated,thanks.

Those are pretty small fans - so you are correct - should work fine on existing circuit.
