SuzukiGS750EZ Posted May 11, 2021 Report Share Posted May 11, 2021 I'm going to be installing a 4 channel Amp for my 4 speakers. What I'd like to do is figure out which test tones to use for my subwoofers as well as my speakers. I mostly listen to rap via Android Auto. Pandora or Amazon music. Sometimes Sirius right out of the head unit, but that's a rarity. The first thing I believe I need to do is figure out where the head unit clips, correct? Then, figure out at that volume with the test tone, where the speaker amplifier clips. Lastly, where the subwoofer amplifier clips. -test tones for speakers and subwoofers? -how to figure out where HU clips? What do I play? I set up my subs a long time ago with an o-scope and remember looking for a smooth sine wave peak. My speakers currently run off of head unit power but I'm planning on setting up an amplifier for them. Thanks! Link to comment Share on other sites More sharing options...
