| What i do to find the freiquency is put a 10" sub in a 1 cubic foot box in the center of the vehicle. And burp it through the frequency's. Once you have found the loudest note .charge and cool .than start over 3 notes down from your previous peak .and re confirm the note. Than build for 2 hz below the note that you peaked at.

| It can be a entry level 10. And turn it up to a appropriate volume for the sub . Keeping the same volume through the testing | |

| K. Ill jist scoop a sa-10 or something. Onlu amps i have are the k5's so that should be interesting. Should be easy to find one of those though.
What about box sizong for the heavyweight? Ive never messed with one. Are they like the apx sizing wise? I was thinking 3.5-4 cubes with a good size port. | |
