COP Security 15-VA101H 1 Input to 1 Output, Gain And EQ Adjustable Amplifier

hey guys rob panes of jail audio here today we're going to walk you through our recommended 9 step tuning process to set the input sensitivity or gain on your amplifiers it's very important that the input sensitivity is properly set so we can get optimum performance from our amplifier without excessive clipping which could lead to distortion for sound quality and damaged speakers so let's go take a look today we have a Honda Civic with an XD 400 / 4v - that'll be bridged into a two channel operation and in XD 1000 / 1 v 2 that will be wired to a 2 ohm load before we can set the input sensitivity on the amplifiers we'll need the following items a digital voltmeter that has the ability to read AC voltage a test CD or file that has a sine wave recorded at a 0 DB reference level it's very important not to use attenuated test tones the sine wave needs to be in the frequency range for the amp
