never knows best Posted April 4, 2014 Report Share Posted April 4, 2014 http://support.alpine-usa.com/products/documents/OM_CDE-HD149BT_EN.pdf Notes • HPF (high pass filter): Cuts the lower frequencies and allows the higher frequencies to pass. • LPF (low pass filter): Cuts the higher frequencies and allows the lower frequencies to pass. • Slope: The level change (in dB) for a frequency change of one octave. • The higher the slope value, the steeper the slope becomes. • Adjust the slope to Flat to bypass the HP or LP filters. • Do not use a tweeter without the HPF on or set to a low frequency, as it may cause damage to the speaker due to the low frequency content. • You cannot adjust the crossover frequency higher than the HPF or lower than the LPF. • Adjustment should be made according to the recommended crossover frequency of the connected speakers. Determine the recommended crossover frequency of the speakers. Adjusting to a frequency range outside that recommended may cause damage to the speakers. For the recommended crossover frequencies of Alpine speakers, refer to the respective Owner’s Manual. We are not responsible for damage or malfunction of speakers caused by using the crossover outside the recommended value. Link to comment Share on other sites More sharing options...

finkster Posted April 4, 2014 Report Share Posted April 4, 2014 NO. Turn it to flat no matter which frequency you choose and the filter will be OFF. Please just follow my instructions.

Please just follow my instructions. explain why you think the x-over on the amp is better please- It's not. He can do either but he shouldn't do both. That's my point. I don't know if that head unit has a better crossover than the amp or not, and I'm not looking into it. The one good thing about using it would be to ensure the front and rear channel slopes are the same. Passat use whichever one you want but don't use the one on the head unit and amp at the same time. Use one or the other. DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...
