is there a general rule of how many components you can run off a single remote turn on lead? or is there something that must be added when running say three amps, and an active crossover, so 4 total devices that need a remote?

I am no expert, but I have ran 3 remotes before without any issues. Electronically, I see no issue with running 1 remote across multiple sources, but then again, I have not gotten into high end audio, competitions, ect, so I am unaware of any possible negative outcome.

Problem is most remotes have only about 250 or so miliamp capacity. When you get about 2-3 items you run a risk of overdrawing that circuit. In essence, burn your remote turn on lead out.

Anything above 3 devices should have a relay.

would i need just one, like this little guy?

Yeah, use a relay.... anymore than 2 items off the remote is a bad idea unless youre using a relay....

i am only using two amps right now. but now i am looking to add another kicker zx200.2, ssmb6 for my front doors (i finally got around to taking the doors panels off and checking and they should fit quite nicley), and kx2 crossover in conjunction with the amp's crossover to bandpass them between roughly 60 and 150... depending on what sounds best.

i love my q-logic kick panels for their imaging, but they aren't the best for midbass response. this is why i am going to try relocating my midbass to my doors, where many people get great results. i even think i remember someone on here writing that one of their favorite set-ups was tweeter/midrange in kick, and midbass in the door.

Actually no not that relay.

The problem is it pulls to much amperage for some remotes.

Thats what I use in my remote saver boxes

and just one? or one for each?

if you have 3 or more devices being triggered, use a relay.
othrwise you'll end up burning out the trigger/remote circuit in the head unit.

i got that part, but no one answered the question of, do i need just one?
