The amp needs an RCA input to communicate with the head unit. SOLDER the wires that come out of the head unit for the front speakers to the SNI-15, making sure that the polarity and right/left is correct. Do this for the front and rear speakers if you have a 4 channel amp. Cut the wires if you add new speakers and run the new wire from the speakers or sub box directly to the amp, or skin back the wire insulation and tap on if you use the factory speakers :( then plug your RCA cable from the SNI-15 to the input side of the amp. Don't forget that most new cars have their own amp so you might have to locate it and bypass the speakers wires around it. Don't make a mess in case you have to put everything back to factory for resale. You can avoid all this by installing a new/modern head unit with built in RCA outputs for front, rear, and sub woofer. I hope this helps. Ray
first you need to run a power cable for the battery to where ever you are going to place the amp DO NOT hook the cable to the battery until the very last just wire it to the amp for now.next you will want to ground your amp hook the ground wire to the amp and the other end to a solid piece of metal in the car this is very important if you don't get good metal on metal contact you'll blow a fuse. If you can hide it well strip back a bit of carpeting and use sand paper to remove all paint from the metal and drill a hole for a screw. once that is finished you will need to run a remote wire from the amp to the car stereo usually these are the blue wire on the harness in the dash. once that is hooked up run the rca cables (reds and whites) plug in to amp and then in to back of cd player. once this is all hooked up and fully secure hook the power cable to the battery make good contact and if everything is grounded right you should get the lights on in the amp. Next step hook up the speakers run speaker wire from the amp to your speakers make sure negative goes to negative and positive to positive or you'll get clipping and it will sound like ****. that's pretty much the jist of it. if you have any questions let me know.
well let me see i can bet something happened so what happened??? i bet the amp is not working right? hahaha here's my sign right!!! all right enough fun. is the light on the amp coming on? you might also need to turn the key all the way to the run position, if not wired exactly right then amp will only power up when vehicle is running or key is in the run position i need to know this before we really go any further. let me know so i can get you up and running quickly.
With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring and speakers need to be checked. If it still shuts down, the amp likely has blown output transistors.
it might not be the amp that is not working it could be the sub or sub's. Try takeing a sub out of the box and look down the hole in the center of the magnet on the back of the sub and look and see if you can see any wire's or any thing that has come unwound in the sub and if you do see wire's then you have blown your sub. If you dont see any wires then you could completly disconect your amp for 20 to 25 minutes and then plug it back in and see if that fix's your problem. If none of this works then you can take your amp to an audio store and have them test the circut board in your amp.
