i want to add some speaker systems in my Suzuki and while searching for the stuff on the internet i for one site planetonline.com ... here i founf what i wants to install in my car... they are Lanzar LANZAR OPTI 600 Watt 5.25" C..... please tell me where the rates are ok and can it be installed in my car....

If you plan ahead and try I'll bet you can fit what you want where you want it. Lanzar has good equipment from what I know of them - but I, unfortunately have no idea on rates, but crutchfield.com has a large selection of such things (I can't be sure they have Lanzar or not though).
