Anyone here knowledgeable on this stuff? I have a 2008 Silverado extended cab. The stock system is so bad, really a shame something of such low quality was put into such a nice vehicle. Probably want to go with new Stereo, 4 door speakers and 1(maybe 2) sub because I like having the extra space in the back. Size specs Spoiler Radio opening Non-standard dash opening (special integration package required) Usable space behind your dash for a new stereo: 6.971" Radio types that will fit in your dash: 4"-tall ("Double-DIN" style) 2"-tall ("DIN" style) Direct replacement (radio designed for your dash) Front speakers Front Door: 6-3/4" Your factory speaker doesn’t match any aftermarket speaker size exactly. Here, we list the largest speaker that will fit in the factory location. As you shop, we’ll show you all options for this location. Rear speakers Rear Door: 6-1/2" Your factory speaker doesn’t match any aftermarket speaker size exactly. Here, we list the largest speaker that will fit in the factory location. As you shop, we’ll show you all options for this location The thing is, I need to go pretty much 100% KICKER, because I can take advantage of their accommodation with Best Buy(as much as I hate to go to best buy, I have to get it from BB) and get this stuff like 70% off retail. It's hard to set a budget, because the prices will be a lot less then listed. So I think what I need is just suggestions on some mid range products then I can look and see what the price for me will be. I need everything; wires, amps, speakers ect. I went for this same project last summer before I could get this discount, now my sister is marrying into it lol. I can get a discount on their install stuff too. The main problem is there is almost no room for any type of amp or box, hopefully the morons at geek squad have done my truck before. Thanks for any help!
