Hi, toying with the idea of building my own sub. Can anyone help me with the following: 1. A suitable book to get me going. Did a little circuit design on my HNC a few years ago but very rusty! 2. Where to buy a decent driver either in the uk or abroad if they ship to us. 3. Best place to buy components for the rest of it. 4. Any opinions on subs you've built yourself and an idea of the cost. Any help greatly appreciated. Cheers in advance.
