thanks so much SJN, that was a fast and speedy reply, i am very green, first time you know. please keep a watch here now and then as i will be back for more help i am sure. and thanks for giving me the motivation to purchase my first sub, when i saw yours i knew that i had to fullfill this lifelong dream of mine, and which model to start with. also that i could ask someone like you questions and that was a huge step in making me believe that could do this, thanks again SJN
