Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

I'm setup a little differently than the average system. My head unit puts out an unclipped signal of 4.99 Volts at maximum output on the volume pot. I keep my volume pot at maximum output (62 on the deck's readout). That gives me as much fire going down the lines as possible. The signal then goes to my Bit One (soon to be PS8). The processor then takes it and has a field day. The signal voltage then gets sent to the amplifiers. Both the processor and the amplifiers have clipping indicators (on the GUI and side of the amp respectively).

I take a 1 kHz tone at 0dB and blast it though the chain (no speakers on the amps). It take an o-scope and read at each point, all the source outs, processor ins, and the amplifier ins for a smooth sine wave. From the sine wave reading kn the scope I move up on the amp gains since I start with the gains all the way down. I go until I see clipping and then back it down until I see a smooth wave.

Why the test tone? It's a mean tone at the highest output level I can get off the information on a CD. That means I play it safe and never have any clipping no matter how loud. Therefore, I don't need to spend the time and money with constructing tweeter protection or launching speakers into outer space.

It works for me. :)
