[QUOTE="VWBobby, post: 7293237, member: 624844"] STFU. You want to give advice and don't even have a system. The advice you give is bogus and tell people they don't need a DMM, GTFO. To answer the OP's question: If you set your amps to a 0 DB test tone, your system is generally too quiet for normal operation. I recommend a -2 or -3db test tone. Measure your voltage on the AC setting of your DMM. If you play a 50hz test tone and get lets say ~2V on your RCA's at the amp, set your gain to around 2V if your amp is marked by voltage on the gain settings. If you have an amp that is more RMS than your subs can handle, you need to set your gains to the FINAL POWER coming out of the amp speaker terminals. There are charts online for Volts - Watts conversion @ various ohm loads. This way you don't blow your subs setting the gain to the head unit power. Setting your mids/highs is the same method, just use tones that fall in the same range as each gain you are tuning (if active). [/QUOTE]
