Help with 4 channel amp
Well after spending all day outside and tearing the car apart, i have finished installing new speakers and a 4 channel amp.
Full System Specs:
Headunit: Alpine 9885
4 Channel: Alpine MRP-F450
Front Speakers: Polk Momo MMC6500 Components
Rear Speakers: Polk Momo MMC650 Coaxial
Sub JL Audio 10w2v2 w/ 330 watts from a rockford fosgate amp
I have no idea how to tune the 4 channel amp. I have never done it before and i don't know how. Currently w/ the factory settings i'm missing midbass. I have the crossovers on the Components set to -3db for the tweeters because at 0 they were way to bright. I have the headunit 0'd out. Any advice on how to set or what to set my 4 channel amp to?
Thanks

Generally speaking it depends on a few things - 1) choices the amp controls give you, 2) how low in frequency your other speakers are playing, 3) how much bass you like relative to the other speakers, and 4) the filter slope (attenuation rate) and architecture. Many people set both the LP (low pass) and HP to the same setting (usually around 80Hz) and find it adequate for their purposes. Sometimes it's beneficial to "underlap" them, with the HP ~80 and the LP ~60Hz or less, but it mainly comes down to personal taste. If you're a 'basshead', then try setting them the same and see if you like it, as that should provide a lot more output in the 60-100Hz range than you'd get with underlapping. You'd probably also want them both set the same if you want LOUD bass but also want the main speakers playing at a much lower level. If you're not interested in bass as much as overall system sound quality, or if you find it too "boomy" with them set the same, then try underlapping, as that will reduce the unwanted boom, while still providing the low bass.
*Disclaimer - The above is only intended for "casual listeners" who want to set it up quickly by ear. It won't be adequate for those serious about SQ or autosound competition.
