[QUOTE="CarAudioGuru, post: 4965592, member: 600532"] Simple. Measure the AC volts out of the amplifier. Start off with amp gains at absolute minimum (fully counter-clockwise) Make sure your mid/tweeters are off for this part. Put some of your ""Bass That Ate the Earth" type music on, crank the gain on your headunit up about 2/3'rds of the way up (if it reads digitally the volume level and lets day 35 is max, turn it up to 30-32) Now turn the input gain on your amplifier up till it distorts. If you are going to use a remote bass control have it pre-adjusted to all the way up while you are doing this Just make sure that the biggest number you see is NOT greater than 33 volts AC. Hopefully a REAL DMM (like Fluke), but pretty much anything will do. If you want to be ultra cool, do a 5dB gain overlap (harder to do as you need a O'scope)..but the REAL way to do this. But the meter "trick" will save you a lot of issues, and it is simple. Have fun, good luck. We are all here to help you. [/QUOTE]
