[QUOTE="itsblown, post: 7983423, member: 636031"] It doesn't matter what your pre out voltage is set at on your head unit as long as the gain on your amplifier is matched to the RCA voltage its receiving. Bassically if you set the gain right it doesnt matter at what level you set it at. However some amplifiers are set up to handle higher voltage inputs and when you use a lower voltage head unit, like 2 volts and down, even with the gain set correctly there can be a white noise sound, even though the amp isnt clipping. So with your 2 volt head unit you probably want to set the gain with the pre out voltage turned as high as it can possibly go. The only problem is you dont know when your head unit starts clipping, so with the subwoofer pre out voltage at 8/8 you may already have a clipped signal. I would play it safe and set your gain at 6/8 enless you have access to an o scope and can test where your head units max volume/ max subwoofer pre out level is before clipping. [/QUOTE]
