multiple amplifiers

when using multiple amplifier setups, for the remote turn on, can you always daisy chain it from the last amp?(like 10 amps something crazy like that)

yeah thats fine but if there are more than 2 amps you need to use a relay because the remote output is usually only 500mA. after about 2 maybe 3 amps it doesn't have enough current to keep that many amps running. wire the relay like this: 30 - constant 12+ 85 - remote output from the radio 86 - ground 87 - output to your amps

holy doodie that seems confusing haha! and anything different for rca's?

best thing to do with rcas is to run a pair for each 2 channel or mono block, and four sets of RCAs for a 4 channel. if your amps support it you can daisy chain the RCAs fro amp to amp. you might get some signal loss depending on how many amps you are hooking up. if your radio supports a full range of RCA outputs ( front, rear, and sub) you can just run the RCAs straight from the deck to whatever amp you want on it. the real solution would be to buy an active 3-way crossover that would turn your front RCA output and split it up into front, rear and sub. but, it would also raise the voltage of your rcas and probably sound cleaner and also it should give you a little more control on your sub. it will also let you play with individual crossover points and maybe even the slopes. those cost about $100 to $160 for a decent one and in my opinion it's worth every penny. but all those are just options anyone of them will work.

not it really isnt. its not harder than wiring a set of speakers. all a relay is is a switch. what is happening with it is when you turn your system on it activates the relay and it flips an internal switch, which in this case will send power from a higher current source like the ignition harness to your amps' remote wires. this wire mush be fused, a 3 amp fuse should be good but you can go with a 5 amp if you have to because 3 amp fuses are kind of hard to find.

here is a picture, should make it easier  https://www.the12volt.com/relays/relaydiagram47.html

86 would be the remote wire from the Head Unit.  87 is the remote wire output to the amp. you can see that 30 is 12v constant, and 85 is ground

If your cousin is such a good installer, and he will install anything for a 6 pack; why are you talking to me?

hm. interesting, well if i ever do a crazy setup like that ill know what to do haha, and are you able to daisy chain the amps if say like you have three? two for subs one for mids/highs?

you can but you will lose the benefit of a dedicated sub gain on your radio. you will need to run a full signal RCA from the front output and chain it from your high amp to your low amp using the LPF on the bass amp to filter out any high frequency from your subs.

but it would be best to have a dedicated front and rear and even sub outputs on your deck right/?

That would be easiest and give you a lot more control depending on the deck you were using. There are always ways to make it work if you had a headunit with less.MECP Advanced

Make your life easier and buy a DMM.
