new car, new system, power, no sound

Then either your amps are bad or you have too low an impedance load on them - or there is a shorted speaker or speaker wire on both of them.  Or maybe your system voltage is too low and they are shutting off on low voltage (it needs to be above 10VDC usually.)  It's unusual that two amps would have the same problem which leads me to think it's an installation error or system voltage is too low.  You may need to get help from a local pro.Support the12volt.com

System voltage as in voltage from the battery? Maybe thats it. I have a capacitor also, the digital kind, it reads 7.0-8.0.. Is that the voltage?? Maybe thats the issue, if so, what is it I need, a new battery? I am hoping to get this done myself as I was supposed to leave today, and no shops are open till tomorrow

Yes, that's the voltage.  Can you start the car?

I have to take off... if your battery voltage is that low the amps will stay off.  If you run the car and they still don't work, there is something else going on.  Good luck and drive safely!Support the12volt.com

Well I just bought a new battery. Still the same thing. And the cap still reads 8.0 wth?! What could be wrong?? I have a 4 gauge wire ran from the positive terminal of the battery, less than a foot away is a 4 gauge in-line fuse, then 4 gauge ran all the way to the capacitor, 4 gauge from the capacitor to the distribution block, 8 gauge ran from the distro block to each amp. 8 gauge ran from each amp to ground. remote wire ran from head unit to amps rca ran from front speaker output on hu to front speaker amp, plugged into ch1 ch2 inputs rca ran from subwoofer output on hu to subwoofer amp, on L/R inputs speaker wire ran from sub amp to terminals on enclosure speaker wire ran from enclosure to sub sub wired in 2 ohm arangement as layed out by the12volt's info speaker wire ran from speaker amp to front door speakers harness adaptor plugged into oem harness

What is the voltage at the amplifiers? Don't rely on the cap's read-out. Use a VOM, and check it directly. Also, post the voltage of the remote lead, please.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Try eliminating your cap. If you are using only one cap for two amps, that can lead to voltage drop. The first amp in line with the cap is probably the one that has the power light illuminated. The second amp simply isn't getting enough power. Good luck!

Sorry about the late reply. Ended up going out and getting loved up like the economy last night, lol. So I decided to mess with the car more, I removed the capacitor i had and wired the 4 gauge power wire directly into the distro block after trying what i thought was everything else.. Now the speakers work!!! BUT, I still cannot get the sub to work. NOW the sub amp power light IS on, the protect light is NOT on. Sub out is set ON in the hu settings. I tried re-arranging the speaker wires on the amp channels and still nothing. Any ideas now?? Thanks again for all your help!

You are not getting enough power to your amps. My opinion is to make sure your alternator is capable of producing enough amperage to supply your hungry amps. I would also replace the 4 gauge wire with 0 gauge. Use 4 instead of 8 from your block to your amps. Good luck!!

Well figured out the sub thing. Somewhat. Everything works now, YAY! But, I have a mono block amp. It lists what power it makes at 2ohms but wont work when i wire the sub in 2 ohm? To make sure i'm doing it right, I had one + wire going to one voice coil's + terminal, and one - wire going to the OPPOSITE voice coils - terminal. The other two terminals empty?
