now i am trying to decide if i want to go with infinity kappa, boston acoustics, or fosgate for the door and deck speakers in the car

then for a 4 channel amp should i go with the fosgate punch 400.4 or the alpine mrp 450

any suggestions

 

I've heard all three of those speaker brands, Boston Acoustics sound the most natural to me. But, listen for yourself and make a decision. Sound is personal.

As for the amp, I own the little brother of that amp. I don't think you'll be let down by it.

 

which amp do you have the lil brother of the us acoustics alpine or the fosgate

 

Alpine.
