Does any one know that should I change the head unit first or change the speakers first on the stock evo audio system to improve my sounds quality. Thanks

 

y not do both at the same time? i'd probably change the head unit first.

 

I agree! for a better power output, your speakers will sound a lot better... checkout alpine H/U sounds pretty decend, then later pair it with pioneer three way speakers 6 3/4 all the way!" no braket needed" It's what I have on my car...quality sound for a good prize...

 

the head unit helps out a LOT!!!!.....we did some experimenting with my car and the factor hu and a new sony and two different amps and two different 12"subs the head unit allows for more sound and clearer sound

 

ya man, if you change the speakers first, they'll be underpowered, and might even sound ****tier than stock. head unit first!!!!
