Front Speaker upgrade for classic

anyone recommend a decent Front Speaker upgrade for classic or know the dimensions.
I dont want to go rear 6x9's and sub route if i can get a set of fronts with decent whack out of them.

Had a set of fli speakers in my classic and they were decent.

If you've not got sorted yet I'd recommend Infinity speakers. They're great sounding and pretty durable, I've had the same pair of 16cm ones between two cars and they're still able to blast some heavy duty rock 'n' roll and bass heavy electronic music out after about 5 years

where can you buy them?
