If i were to hook up 2 or more amps how would i wire the remote wires (usually the blue wire on the H/U)  of multiple amps with out burning out the H/U? I heard I would have to use a relay to do this is this correct and if so how would i wire it up?  Also would I need a relay for each additional amp? or can one relay be used for 2 or 3 amps? Thanks in advance for any info.

MY bad I see someone has asked this question about multiple amps and remote turn on wires. Let me know if this is correct.  They say it is possible to run one remote wire from H/U to one amp then run a second wire from the 1st amp to the second amp basically saying i could daisy chain them is this correct? If so is this possible when adding a 3rd or 4th amp? Thanks again for any info.

Daisy-chaining is OK as long as you do not overload the HU circuit.  Most HUs will output a couple of amps on the remote lead and most amps draw a few miliamps, so you are generally safe to switch two or three pieces of equipmnet (amps, crossovers, etc.)  If you start adding on four or five or more, or if you add fans or other switched equipment, you will definately want to add a relay and fuse block.  One relay will do the trick for everything, again depending on the total current draw you are powering.
