Just got my B2 from the Ups man today as well, also curious to the settings. Waiting on the sni-35 and Moto 602's to show up. From what I have read I am guessing HPF, turn it to about 80 on the dial for the bypass. I am going to use my volt meter for the gain to about 24.49 volts, (please correct me if I am wrong, seems a little high to me).

Hi,

Using a volt meter will not tell you how much distortion, just overall power. Using a stock HD radio I would worry a little about that high of voltage. In theory it would be correct for that amp making 150 watts into a 4 ohm speaker (as per the amp spec) but in the real world you do need to worry about how clean your input signal is, and the stock HD radio is a pretty bad source.

You can compensate for some of the distortion by setting the HPF higher, we normally recommend 60-80hz with an aftermarket radio but have some guys looking for the loudest volume possible on a stock radio setting it to 100hz. There is a trade-off in low end with this high of HPF setting but it will give you a higher volume on the road when using the stock radio.

You could also set the gains by ear, I think that is safer because you can hear the distortion. On a stock radio once you go past about 70% volume it gets pretty bad. I usually set the bass and treble to flat, the amp gain all the way down, crank up a good CD to just before it sounds bad (usually about 70%), and then turn up the gains as high as it will stay clear. Sometimes you will need to go back and fourth a couple times to get it.

Same converter. Only the 35 gives you 5 more watts of input per channel.

Thank you, i do appreciate it. Depending on how the 602's sound in the Rushmore pods i might be looking in your direction for the 7.1's with the pod removal bracket. Ideally i would have liked to go with the the 7.1/2180/14' package, but was a little out of the price range right now with some home improvements goin on, i hope i don't regret that decision lol.

Connect the wire leads to your radio speaker wire. Connect the other end to the amp using RCA cables. Your almost there man!
