Anyone have any suggestions on a decent pair of upgrade speakers for the doors? Preferably ones that dont need any modification?

 

I ordered some from www.crutchfield.com they include the proper brackets and plugs that you need to install them very easily.

I ordered a set of Pioneer and I am happy with them

 

yeah, I'd recommend crutchfield and buying the adapter plugs. Also, unless you buy an aftermarket headunit, the speakers are going to sound like crap anyways. The stock radio is very limited in clean sound quality.

 

All my stuff is in my sig but I used Kicker 6.5s coax in my doors and love them. They sound great and SO MUCH better than the Infinity I had.

I bought polk db series for my rear doors and dash speakers(I have the 7 speaker factory system) The front doors are mid-bass speakers in the infinity system and they only recieve low frequency input from the factory amp/head unit. So replacing those will net you little gain if any because you are limited from the factory.(unless you want to replace the whole system) I got the polk db's from crutchfield,call them,they have great customer service and they can tell you what will and won't work.Crutchfield is excellent to deal with. The center channel dash speaker has no direct replacement available,I just left it stock. Crutchfield will hook you up.

 

Boston Accoustics from Crutchfield--sound great, but I also have a Pioneer head unit, 4 spkr system

 

JL Audio all the way around, put tweets in the dash, replaced 6X9's in the doors and upgraded the 5 1/2 - 6 1/2 in the pillars..... oh and added 2 W3 10 inch subs.
