The speakers these days out the new cars are speakers you can't buy no where else. They are high quality big name brand companies like Polk, Infinity, Bose. Pioneer, Sony, Panasonic and some other electronic companies are not makin quality stuff man

And if you buy a infinity or polk aftermarket the are weaker and cheaper. Bose you better not change no speaker in the world comes close. But the only ones that are probably as good or better than those companies are Kenwood and Alpine. They are speaker companies so they should make good speakers. But Alpine to me are the best components out right now.
