I am building a sub for my car. I have all the required items to build a single or double woofer box. In the past I have designed and built over 20 sub enclosures, I have always designed the enclosure for Optimal woofer performance in a sealed or ported enclosure. I have build a few enclosures that were very small and have had great results.
First off I want minimum weight and size in my trunk. I have 2-12" Diamond D312D4 woofers, a Hifonics Brutus amp thats 500wrms clean at 4 ohms, or 900wrms clean at 2 ohms. I am building a 1.4 cubic foot sealed enclosure. An Optimal sealed enclosure for 1 woofer is about 1.5 cubic feet.
What would you do if you had my parts? An enclosure(1.4 cu.ft.) with 1 woofer, amp, cap, wires would weigh aprox 50 pounds, and the amp would run at 4 ohms(aprox 500wrms) An enclosure(1.4 cu.ft.) with 2 woofers, amp, cap, wires would weigh aprox 63 pounds and the amp would run at 2 ohms(aprox 900wrms) The woofers each handle 400wrms and 900wmax.
I am building the enclosure today, but I do appreciate any good suggestions and opinions. Last June for my sons 21st birthday I built a very small sealed enclosure using 2 Kenwood 12" woofers with a Kenwood amp that puts out aprox 600wrms at 2 ohms. I built is very small because the car it went in was a Chevy Aveo, not much room in the back plus the car doesn't have much HP. We couldn't believe how great it sounds-WOW. But the Diamond woofers I have are much more powerfull. I did Over-insulate the enclosure being that it was sealed, this makes the woofer react as if it was in a larger enclosure.
Thankyou for any good ideas or opinions.
