This is for the HK radio, is it the same harness for the older radio. Hers has the 23 pin connector from the radio? I did not see anything on their site for the 2003. I was thinking I would solder some jumper wires into the wires and run a trailer plug to the rear so I can keep the tourpak detachable. I saw that suggestion in a different thread from UltraNutz.

My bad I was under the impression you had upgraded the radio to an HK radio? The radios from 1988-2005 were Radio sound radio's for Harley Davidson. They were not 2 ohm radios. When you said you were reading the FAQ's and it stated 2 ohm I assumed you had an HK. The 2 ohm HK is from 2006 - up. Okay back to business. Anything you read form Ultranutz. . . Do it.

I have everything wired in, Power is wired direct to the battery with 10ga wire and a 30a fuse from an extra battery tender cord I had. I used the existing stock speaker wires for the input, then the output from the amp goes to the speakers. Used a trailer wiring plug for the tourpak so it is detachable and this is wired parallel. I used 1kHz test tone on cd to set the gain, from my calculation it should be 22 volts with this setup.
Is this the correct size fuse? It had a 7.5 a fuse in and I promptly blew that and put in a 30a but I don't want to burn anything up.
Sounds great BTW. I haven't taken it on the road yet because I wanted to get it dialed in before putting the fairing back on. Thanks for all the help.

For example: if you have a sound stream amp with a 40 amp fuse your inline fuse to the battery should be 40 amps or higher.
