Hey guys, I bought Infinity Kappa 693C for the front and the tweet will go up in the dash. These speakers are very clean and are 3 ohm. The Bose are a 4 ohm speakers. So the 3 ohm speakers will play loader than the stock speakers. This was verified by one of Crutchfeildxs advisers. I am going to use the Infinity Kappa 63XF in the rear doors. Will be using dynomat on all 4 doors. I'm going to see what that sounds like, then if I need more power go with Kicker 47KEY200.4 channel amp. It's rated at 50 watts at 4 ohms. For 3 ohms it's about 67 watts. I f I go with this amp the I'm going to go with 10" power sub- Kicker 51HS10 . I have used Infinity speakers before in my 2005 GMC SLT 1500 with Bose. With that truck I used a 50 watt amp and it sounded great. I used JL Audio in my boats and they are great speakers also. So that's my 2 cents on my 2018 GMC 2500 Denali Crew Cab 4x4
