ok so i wired the subs to the amp now, the positive (Red) goes to the battery, the ground (Black) is currently grounded to the metal under my drivers seat. My question is does it matter the color wire is that goes to the stereo? Can i use a red or black? Does it really matter? If not, where exactly would i hook it up behind my aftermarket sony headunit?
if your talking about your RCA wires that go from your stereo to your amp. the color doesnt matter as long as left and right are hooked up correctly
If your talking about a remote wire there should be a blue wire with a white stripe coming out of the wiring harness for your receiver/head unit... And run a wire from that to the remote terminal on your amp. All this does is send a 12v signal so when you turn the key on your car/truck it signals the amp to turn on. If your head unit does not have a remote wire you can run a wire from your amp to your ignition..
I was once considering of tapping into the 12v constant on the HU like I do in 95% of the installs i've ever achieved. Are you talking about the far flung wire connection? If so, you commonly mean the accessory wire, now not the steady wire; and to be able to be a hindrance within the Trailblazer in view that there is no accent energy wire in the radio harness. I might recommend using a line output converter that has a developed-in trigger circuit, so it will flip the amp on when it detects an audio signal coming from the head unit. There's no excellent position to connect a faraway wire in a Trailblazer with a manufacturing facility head unit. You could hook up with the accessory vigour output on the key change harness (a thick brown wire) however then the amplifier will flip off with the important thing, alternatively of staying on unless the door is opened like the radio does. The Motorola box is for the Onstar procedure, and there isn't a motive to do something with it at all. Sixteen feet of vigor wire maybe sufficient or would now not; depends upon where you position the amp. The battery and firewall access is on the motive force's part, so in case you maintain the amp on the driver's aspect of the vehicle, you'll in most cases have ample wire.
ok man to answer your question NO , it does not matter what color the wire is. what DOES matter is that your using the same brand wire,(just because some 4 gauge wire is bigger than Other 4 gauge wire) and it MUST be the same gauge wire for positive and GROUND. You will also need to run the REMOTE TURN ON wire from the back of the headunit to the REM on the amp. (without this wire the amp does not know to turn on. Next thing is your RCA cables these will run from the back of the headunit to the input on the amplifier. Last thing (OBVIOUS) is the speaker wire both to wire the subs to the correct ohm load and to also run from the speaker terminal cup (if you have one in the sub box) to the amp. * Looking back i think i miss read the question, no the wire color does not matter, just make sure its the same size as the wire from the headunit (not bigger or smaller) so probably around 16-18 gauge wire, color does NOT matter.
