Filters and preouts..

Pao Trifyllara New member Username: Paogr AthensGreece Post Number: 8 Registered: Dec-05	Posted on Sunday, April 02, 2006 - 00:15 GMT The filters on a headunit (HPF,LPF) affect the internal amp and the preouts or one of those? I'm asking because my friend's headunit has 1 preout and he has hooked a 1-channel amp on it and a sub. The rest four speakers run from the headunit's internal amp. If he set the HPF at 100Hz will this affect the preout or not?

HPF should only affect the mids and highs though. the LPF should affect the sub.
