Bestbuy is the best place to get your system installed PERIOD
only if they install everything and no one else touches it. I got my deck installed there and something wasnt workin right so I had this other local audio store to a full check on my whole stereo system and it came down to the RCAs on the deck. so I go back to BestBuy and they say, "well since someone besides bestbuy has messed with it, all warranties are now void whether you paid extra for them or not." but I got lucky and the guy I was talkin was cool and pretended that I didnt tell him about having the system checked out and he got a me a new deck. BUT on another note, maybe the BestBuy that YOU go to is awesome but people are different everywhere so it might be ****** somewhere else.
Honestly, Ill never have BestBuy install anything for me again cuz of the local audio store down the street from it cuz they arent a bunch of ****** there if your just straight with them and they will stand behind what they do and help you not try to **** you all the time. AND BestBuy doesnt have JL, Memphis, i dont think they have dynamat, and some other shit but this local audio store does so it would be pointless to buy from the local place then take it to BestBuy and get it installed since the local place will cut down prices on installation since I buy from them.
