I'm considering swapping out my speakers, already done the HU, anyone have any experience with these or know if they would be better that stock ones ?

Pioneer TS-G1643R 6-1/2" 2-way car speakers — for 6-1/2" and 6-3/4" openings at Crutchfield.com

Pioneer TS-T110 7/8" poly dome tweeters at Crutchfield.com

 

Just about any speakers would be an upgrade to the stock ones in the Fit. They're a step above garbage.
I just bought 4 new Polk 651s for $124 shipped on ebay. They go for $99/pair at Crutchfield. Can't wait to put them in. Haven't figured out what to do about the tweeters. I may just disconnect them.

 

You've obviously never sat in an Altima with the Stock HU & Speakers... Sitting in the Fit is like Paradise in comparison.

Personally, I'm a fan of the Infinity Kappa components and would recommend them. I've had the Infinity Reference in my 1st integra but with my GS-R, had Kappas. They are worth the money but don't necessarily have the low end that some others have... I'd rather have quality midrange and add woofers or subs for the lows than to have a set of 6.5" components try and run the full range.

PM me if you are going to buy from Crutchfield and have never bought before. I have a referral code that will get you $20 off I think.
