If I put subs in my truck, (i'm looking at JL's stealthbox with two 8's), I don't want to remove my factory CD player. Is there an adapter I can buy to hook everything up to my factory CD player so I don't have to buy an aftermarket one. Any input would be helpful on this setup. Thanks

 

Yes there is. Just go to your local stereo shop and tell them what you're doing, although I would recomend buying a head unit. If you are going to have any kind of system you need a decent head unit. Just my 2 cents.
