Hey, BT -
How can I test whether the RCAs are getting signal?
No, I didn't touch anything on the amps in terms of gain settings. That did not occur to me as I was planning to rely on my IMPRINT... now I feel pretty dumb. Would it be typical for amps to be set on "0" gain out of the box? Could that be my problem. I'd be relieved but also feel totally stupid if it were that simple!
thanks - I'll check it out...
Yea amps are typically set to 0. its a dial and you turn it up to raise the gain. Tho at 0 gain, you should still have SOME sound...as long as your head unit was turned up. Also to test your RCA's, i THINK you can use a multimeter.
I've honestly never tried it, but I am assuming you just play music and test the connecter, ground the black and touch the red to the connector (someone chime in please on this, because I am just guessing).
You will need to tune your amps to your system also. This is done by putting your headunit at max volume with no processing on, all filters off, and your EQ at 0. make sure your amps are at 0 gain as well.
You will want to obtain 2 files. a 1000hz sound file (for speakers) and a 60hz file (for subs). You put the cd in and play at max volume (might want ear plugs, it gets LOUD). then while you are in the back you adjust your amps gain. You turn it up until you hear an audible change in tone (you'll see what I mean). Then you turn the gain back a tiny bit.
Do the same for the sub. I would unplug the RCA's from the speaker amp when doing the sub (just incase). Once that's good turn down your system and put in your favorite cd. then set your high pass filter (speakers) and low pass filter (subs). I think I set my speakers to cut off at 125hz (somewhere around there) and sub to start at 125hz.
Your head unit probably also has a HPF and LPF built in that you can set these frequencys at.
If you need those two audio files, I have them on my PC at home, I can email them to you tonight if you'd like.
