Speaker Question

I just installed my Alpine deck in my 98 GSX with the infinity system and I was wondering where I can get connections to hook the stock amp up to my deck. Also are all the speakers hooked up to this amp i haven't looked at it yet and don't really feel like taking my seat out unless i have to.

If you go to bestbuy curcitcity any stores like this they will sell plugs that will plug into the factory harrnes to the sterio no cuting just 2 clicks and your done.

Cool thanx
