    Head unit crossover control vs amplifier?

    Any thoughts on which is best?

    My head unit and amp can both set the low pass/high pass filters on the sub and front components. The HU can go a step easier and set the crossover values by specific frequency instead of a slightly random dial on the amp.

    The HU can also do some wierd centre stuff on the frequencies aswell...

    I'm a bit curious on which may be the better setup?

    Well no replies but I played anyhow...at least with the rear/sub output. I set the HU to output 80Hz and below to the sub. Fairly noticeable difference, I must have been reasonably well off 80Hz on the less than accurate dial on the amp!

    most people use either one crossover or the other but not both. The gain control is to match the output of the CD player with input of the amp.

    The bass knob is like an EQ, probably set to around 50 Hz. So if you set it to +12 dB then the freq's around it will also be effected. so 40 & 60 Hz might be at +9 dB and 30 & 70 Hz might be around 6 dB or something like this. On the other hand, the Sub W. control effects ALL the freq's being sent out of the Sub W RCA jacks equally. This will require you to use the crossover (LPF) on the CD player.
