This diagram is ONLY for the SC, EX, and EX-P with the factory double-DIN radio, amplifier, and subwoofer. This is NOT for the DX or LX. The first picture shows how the radio is basically wired from Honda. The radio puts out a line-level low-level signal to the amplifier thru the big black harness. It puts out a mono signal for the subwoofer via the small black harness with white guts.

The amplifier then sends the amplified signal out to the speakers and subwoofer. Note the sub is dual voice coil but uses a mono signal. To view links or images in signatures your post count must be 0 or greater.

Adding a stereo to a vehicle with a factory amp — should you bypass the stock amplifier or use it?

Find More Posts by BigAl To hook up the radio to the factory sub, you will need a male RCA plug to splice into the small black subwoofer harness. The easiest way to do this is take an old RCA cable, cut off an end and strip back the wires.

On most cables there is an outer shield which is the negative, and a center conductor which goes to the pin for positive. The diagram pic shows how an aftermarket radio would be hooked up. Metra makes a harness which allows you to hook the radio's RCA outputs to the facory harness more on this later.

You will also need an antenna adapter. For the subwoofer connection, splice the RCA's negative wire to the red with white stripe on the subwoofer harness.

Then splice the center positve conductor to the red with blue stripe. The pink with black stripe does not get hooked up. Since the signal is mono, you don't have to hook up both channels to the radio output unless you just want to. Splicing the wires could be done several ways Another option would to use t-taps which you can buy at most auto parts stores. T-taps clamp onto the wire and when squeezed with pliers, a small blade pierces the insulation to complete the connection.

Another option not recommended if still under warranty is to simply clip the black connector off and splice the wires directly. The Metra harness mentioned earlier makes life so much easier, however any aftermarket wiring harness will do.

You will just have to put male RCA plugs on all of the input wires. If your radio doesn't have RCA outputs, you will have to install a line-level converter on the radio's speaker outputs. This will convert the high-level speaker outputs to line-level to go to the Honda amp.

A good point was brought up in another thread. You could just run the highs off of the radio output and run the sub off the facory amp if you wanted to. Either run new wires to the speaker locations or splice into them at the amp outputs.

The amp is located behind the passenger-side kickpanel.

See here for the amp's wiring color code. This needs to be stickied The only thing I would say is that I don't condone the use of t-taps, but to each their own. This should answer a lot of questions in the future, nice job. Sony XM-1S mono amp running a To view links or images in signatures your post count must be 0 or greater.
