I ordered these only to replace the blown tweeters in my VW. Install was interesting, just positive and negative wires which were unbelievably thin, must have been 28 or 30 guage. I think i counted about 15 or 20 copper stands. Sound quality was on par with with the stock speakers. I think for $40 i should have gotten tweeters that sounds at least a little better than stock. Since then i have upgraded entire system; new HU, 2 amps, new componenst all around. I wouldn't buy these again.
