Need help with amplifier, speakers & subs

[Armstrong55]

So i have 2 subs hooked to an amplifier right now, i want to also hook my 2 or 4 door speakers to an amplifier also. So i know i can't use the amp that is hooked to the subs, but i have another amplifier i can use. But my question is how would i hook it all together so that my subs stay on one amp and my speakers go to the other? I would like a nice diagram to show how. and no i don't want to use a capacitor as it is not needed. any help is appreciated!

RCAs. Send the full range signal to the full range amp

Ok i'm not a really audio guy so, you just saying "RCA" doesn't tell me one bit how to get power to the second amp and still run the wires to it

Same as your other amp. Power wise. I'd recommend taking it somewhere

Honestly u could have googled this first and then created a thread with clarification questions. This answer is probably super drawn out diagrammed on crutchfield. If your headunit is aftermarket you run rca cables from the preouts in the back of the headunit (labeled front/rear). Your existing sub amp would likely be plugged into the sub pre out. If your headunit is factory and you have an line out converter check to see if it is a multichannel(needs to be 5 or 6). Also, if your 4 channel amp is newer, check to see if your amp takes low level (speaker) factory inputs and converts to high level outputs. If so u can use it as is and leave everything else alone. If none of those options work and your hu is factory you can replace whatever is connecting your sub amp to the factory headunit with a module like this:

Any head unit with only 1 pair of RCA is really bottom of the barrel. I'd encourage you to upgrade, but otherwise you could get y splitters and some smaller RCAs to split the signal to feed 2 amps.
