I have just fitted a JVC KD-LHX601 Head unit to my 2002 Allroad and am looking at replacing the factory speakers with something a little better. The factory Sub worked with the After-market Clarion thet the JVC replaced but does not work with the JVC. No great loss i know, but, i do notice the difference without it. I guess i would need 2 pairs of component speakers for the doors and possibly a Sub. If i go for a Sub it would have to be a compact one such as these. http://thebassbin.co.uk/shop/product/products_id/2781.html http://www.icebuyer.co.uk/product.asp?product=21071 Could anyone recommend some speakers that will replace my originals without too much hassle and are these Subs any good? I don`t actually know the size of the original speakers but i guess they are 13 cm? Any help/advice would be appreciated. I have not set a budget but as long as i don`t have to sell a kidney i am open to suggestions and await your expertise. Thanks in advance.
