Hey, i just got 2 small amps that i want to install in my car. I already have one amp installed, but i'm not exactly sure how to wire in 2 more so there would be 3 in total which would power my 2 12" subs.

Any information and help on this would be appreciated.

First, make sure the power and ground wires are proper size for all three amps, upgrade if necessary.  If you are installing the new amps in the same area as the one that is already there, you can use a fused distribution block to accept the main power wire and distribute wires to the three amps.   Ground each amp to chassis, try at or close to the first amp's ground location.  To turn on the amps, purchase a relay and wire it as shown here on the relay page.

Output jacks of one amp to the input jacks of the second amp, same daisy chain from second to the third amp.  All will get full signal.

Ok i understand the distribution block and wiring that, but with the relay, i'm not sure what it means by remote turn-on? And also is the #30 terminal wired to the Distribution block? If not, where is it wired to?

Thanks

Ok i understand the wiring of the distribution block, but i'm not 100% sure about wiring the relay. First off, what does it mean by "Remote Turn-On" at the head unit? Second, is the #30 terminal connected to the distribution block at all? If not, what is the #30 for?

The remote turn on is usually the blue wire coming from the head unit the hooks to #86 of the relay (without a relay this wire would go to the remote turn on on the amp), #87 comes from your power source (ignition or battery), #85 is you ground, and #30 goes to the amps remote turn on.

blue with a white stripe if you have both blue and blue with a white stripe

or your amps will only turn on when you listen to the radio
