RPL Speakers

I replaced the stock door speakers with Infinity Reference 6032cf two way speakers. If you are using the stock amp and head unit you will need 2 ohm impedence speakers. The stock door and rear side speakers are 6.5 inch round. Infinity makes several level of speakers, I found this pair on Amazon for $55.00 and they have much better sound than stock. I have not replaced my rear deck speakers yet, so I am unsure of the size needed.

all speakers in the gto are 6.5" round except for the 2 inch tweeters in the dash. the fron door speakers are a component system with the tweeters, the rear panel are 6.5 2 ways, and 6.5 subs in the rear deck

I would definitely say the Polk Audio db6501 Components for the front

and the Polk Audio db651 NON-S Coaxials for the rear.

These are by far the best budget speakers you can get for our cars. Also a HU upgrade will make a world of difference as well, however if you are just doing speakers these will not let you down.
