hi Quadie, thanks heaps I dont think you could have explained it any better! im quite happy about the fact it'll allow my current sub's they have served me very well so far with their minimal power ive got going to them. im only looking at this option as I really want to keep the factory cd player as long as I can. im not really an audiophile, I like my music but im not someone who cranks super loud, I just like a clean sounding crisp system. and Nomis, ive seen them on ebay from the US for about $200 shipped. I had a long chat with the car audio guy from JB Hi Fi where I live and he told me to stay away from the no name brands.
