View Full Version : Using the head unit crossovers vsersus the amp crossovers

01-23-2005, 03:44 PM
I had an Alpine 9815 in my last car and used the crossovers on the HU (80hz high-pass for my components and 80hx low-pass for my sub) instead of the crossovers on my amp (left them flat). When getting my stereo installed in my new car the installer was telling me that I should use the crossovers on my amp instead of the crossovers on my HU.

I've searched around on the forums but haven't seen any technical information on why I shouldn't use the crossovers on my 9835. Was the installer full of it?

The crossovers in the 9835 work awsome, use away man! I run a 40hz high pass / lowpass at 24db/oct and it is just right for me.
