One amp powering another?

When I got home home today, I shut the truck off and decided to watch the light. Oddly enough it shut off after about 15-20 seconds. I guess thats good, it still seems weird that it stayed on before. I had time to loosen the screws and remove all 3 wires individually and then all together and it never went off. Oh well, who doesn't love a problem that solves itself.

Yes you can. Just don't run one side of the RCA cord to one amp and the other to the second amp (that would make it mono). You would run the Y's to split the right half to make 2 right sides and then split the left half to make 2 left sides. Now run 1 rt/lt combo to one of the amps and the other rt/lt combo to the other amp. Yes you are still going to have stereo. Back in the day when head units only had one set of RCA outputs this was the only way we could run multi amp systems with out running a EQ or a Thirdoctive Eq. Or we would have to run a speaker to RCA convereter off from the speaker leads.

I installed my amps and subs today. I ran the RCA cables from the head unit to the first 150 watt amp and then another set of RCA's from that amp to the 1500 watt amp. One thing I have noticed is that when the truck is off, the 150 watt still has the power light on. I disconnected the power and ground but the light stayed on. If I remove the RCA cables connecting the 2 amps, then it will go off. The 1500 watt amp has an internal capacitor. I was wondering if possibly the stored power is powering the 150 watt amp through the RCA cables. I'm kind of afraid to leave them connected as I dont want it to drain my batteries. Both amps have there own power supply as well.

It's not unusual to have a head unit with one or even two RCA pre-amp outputs. Unless your amp has a pre in & out then the the best thing to do is what was suggested earlier, a pair of RCA Y-cords that allows you to input both amps with the same signal. Jumper the remote turn on wire (or power antenna) to both amps to turn them on via the head unit.

if the amp has inputs and outputs, i would think you would use the outputs for multiple amps (as in very high wattage systems) - that's why they put them on the amps... My assumption is that they have a small voltage boost on each output to allow for low or no signal loss as you split them from amp to amp... if you ran a bunch of "Y" connectors, it seems you would constantly lose signal voltage and gain noise to volume ratio... This is obviously just a bunch of assumptions i'm throwing out there...
As far as your light staying on, you got me on that one... unless it's a cooldown period or a power drain period... if it has something to do with your RCA's then I assume you have some internal problem that is not intentional to the amp(s) manufactuer...
