    Soundstream Rubicon 2500.1d

    Was adjusting my gain this morning using a dmm. Now keep in mind I have a Pioneer DEH-80PRS headunit. Had my volume set to 47, eq set to flat, and had a 40hz note set on pause. Went back and set my amp gain to 0, sonic filter off, sub filter all the way up, and no boost. Put my dmm to V/ac and have it red to positive and black to negative speaker outputs. As soon and I unpaused the music I was at 34v/ac for about 1156 watts. Now I wanted to set for 1200 watts or 34.64v/ac. Hardly any gain adjustment. I was just surprised. Has anyone else used a dmm to adjust this particular amp???

    Forgot to dd, I was using a 40hz straight. Should I use a -5db or -10? Or will this be fine?

    I tried both. .2-2v is where its set. If I turned it to high side at full gain I was only reading 15v/ac

    I see that the preamp voltage on the pioneer 80prs is 5v.

    I gotta go play with the headunit now. There has to be a subwoofer setting I am missing

    Re: Soundstream Rubicon 2500.1d

    I guess I am just gonna have to adjust this by ear. I just went out and played with it and on the 2.0-8v setting at full gain I was just hitting 34v/ac

    What do you mean by that. That the settings on the amp the way I initially had it sounds right??? So I should keep the setting to .2-2v?

    If it's giving you the power you were looking for I wouldn't touch it.

    The lower you're wired to the lower the voltage is so 34 makes sense if hes using 1 ohm (34^2 / 1 ohm = 1156w)

    Yeah the way these 8's are handling this low wattage, after break in I am turning the amp up to 44.72^2 / 1ohm = 2000w.
