[QUOTE="HardofWhoring, post: 8626965, member: 674149"] The right way is to do a relay, like already said. Your head unit might give out the specs, but the two I have had that had it listed, both said to run no more than 500mv off the remote wire. I have only seen the specs for one amp, and it said it was pulling 400mv. I have a real small fan that is listed at 110mv. The warnings will tell you that you can burn up your head unit, by pulling too much through the wire. A standard relay will cost about $5, and give you enough voltage for up to 30 amps.

(Ask them if they will buy you new equipment if it doesn't work). If you are dead set on daisy chaining it, lets be clear since someone already said to run all the amps off of one input. That would be the worst way to do it, and is also NOT daisy-chaining. If you are going to do it, you would want to run your remote wire off the head unit to your amps remote wire input. Then run your second amp's remote wire input off the main power wire going to the first amp, then your third amps remote wire input going to the main power connector of the second amp. Its not the best way, and your amps would turn on in order. If there is any problem with the first one getting power, none of your amps would work, or whatever down the line. Now, in theory, you would then be pulling the same current at each remote in, as if you had run a relay. [/QUOTE]
