i just did the same thing, except I wired 4 in series to give me the 12v. If you wire them straight off the amps positive and negative, then they will always be on. I first hooked them up off the remote wire, but it wasn't suplying enough juice, so I bought a relay, and have the 12v going tot he relay coming off the amp. This way, the leds come on when the HU is powered up.
