04 Trailblazer

I am planning to install all new speakers in my 04 Trailblazer. The specs are Dash: 3-1/2", Front door: 6-3/4", and Back door: 6-1/2". I thought about getting all Infinity Kappa so it would be the Infinity Kappa 32.9cf in the dash, the Infinity Kappa Perfect 6.1 or the Infinity Kappa 60.9cs in the front, and the Infinity Kappa 63.9i or Infinity Kappa 62.9I. I don't know much about the 2 way or 3 way door speakers so advice is greatly advised. I will be hooking an up to them as well but need suggestions.

You will want external amplification for those speakers if you expect to hear their full potential. The kappa speakers are 2-3 ohm. Does your trailblazer have the Bose system installed?

You also want to verify fitment, check on Crutchfield for fitment and if you buy from them they will include all necessary mounting and wiring adapts as well as detailed step-by-step instructional.

Personally, I prefer the Reference speakers over Kappa. But I have done a few installs with Kappa that sounded decent.

No it does not have a bose system, and i plan on getting a 4 channel amp for them. I was going to go through Sonix they are cheeper there

Parts are cheaper, but may lack a warranty and you get no customer service and no adapters. FYI
