splits that are loud but still maintain a bit of quality
 

I would like to change my stock speakers for something a lot louder but I don’t want to lose any sound quality if not I want to make it better. Also it would be amazing if they just went in without modifying anything but haha I think I’m dreaming on that one.

I’m looking at brands along the lines of
jl audio
kicker
alpine
phoenix gold
Rockford
Soundstream
Jbl
focal
image dynamics
Or any other brands you guys recommend?
I have a 4ch amp that is 120w rms @4 ohms
Budget is up to $400au a pair which is roughly $329us at the moment

I really like the kicker QSS67 as I can mount them in the front as splits and mount them in the back like coaxial by screwing the sweeter into the cone as intended and the IMAGE DYNAMICS CXS62 V.2 I think you can mount the tweeter to the pole piece so I can put them in the rear too, any thoughts on them?

or maybe

Alpine SPR-60C and the SPR-60 in the rear
phoenixgold TI265cs and the TI265ps in the rear

Any thoughts?
i like the IMAGE DYNAMICS range but I'll have to import them as in Australia they are a lot harder to find

Cheers guys :)
