Running 2 amps at different frequencies

[Adezmk3]

Hi

Basically I am sure my headunit isn't compatible for these and what I want to know is the term for a head unit that is.

I have a low frequency amp for my subs in the boot, and want to amp my front door speakers, these need a high frequency amp, the headunit does have two outs, but only the option of either low or high frequency output across both.

What sort of headunit do I need?

Thanks

Adrian

I think you should be able to run both just set the switch on your front speaker amp to high if possible. If not you will have to buy a high frquency made for amping loud speakers as there called
