I have 2 Kicker Comp Vr 10's and a 600 watt RMS Pioneer amp. What do I need to connect this to my stock deck. Its a 97 Chevrolet Silverado. Any comments would be greatly appreciated, Thanks
You'll need a line output converter. I don't recommend using it because it sounds terrible when compared to the output of a normal aftermarket headunit.
If you have an ebay account you can get a great deal on a used-but-in-new-condition aftermarket headunit which would be the best idea because most now offer some type of sound control for external amplifiers.
I have a hi-low converter in my durango (soon to be replaced with HU) and it sounds good. Not great, but not poor. And its a easy/cheap add on for subs. And you keep your stock look.
