My sub and box
| Item | My number |
|---|---|
| Sub size (inches) | |
| Sub RMS power (watts) | |
| Sub Vas (from the spec sheet, if listed) | |
| Sub final impedance (ohms) | |
| Box type I want (sealed or ported) |
Box volume
| Step | Number |
|---|---|
| Inside width (in) | |
| Inside height (in) | |
| Inside depth (in) | |
| Volume = W x H x D, then divide by 1728 for cubic feet | |
| Minus sub displacement (about 0.1 to 0.2 cu ft for a 12 inch) | |
| Net volume I want |
Check before I build
- Volume matches what the sub manufacturer recommends
- I checked the final impedance with the wiring plan
- I have the right materials and tools (for example, 3/4 inch MDF)
- I can say what to set the amp gain to later
