I have an 07 mazda6... The factory stereo is horrible, being that the speakers distort badly at high volum and have almsot no bass. I want to replace all 4 speakers 6x8, and maybe replace the front tweeters. Im on a tight budget. I can get them from my auto distributor which is cheaper than any online site.
The brands I can choose from are:
And a few others
What would you reccomend would sound best without adding an amp.
I may add an amp, but if I do I need one with high leverl inputs so I dont have to use a converter or aftermarket headunit.
