Tuning an amp

Hello,

I have a question. I am thinking of useing a ported box. I hear alot of people saying you need to tune your box to a certian number. How is this done? I dont know what I need to do. Any help would be great. If it helps I have 2 700 2 ohm 12" subs powered by a 1000 D Mono Amp.

Thanks,

Greg

tuning your box is using proper port length, size, and area. Its not from your amp its from the box. different port dimensions will give you different tuning frequencys.

Ok I see. Please bare with me. I have never used a ported box. My subs call for 1.5-2.0 feet of air space. When I bought them I was told to tune them around 40 hrtz. What do I need to know in order to do this. Also do I need to do a chamber for each sub with its own port or do one big chamber with one port.
