I bought this pair of Crystal Mobilesound CMPx215 a while back, I had them briefly installed in my car, but sold the car due to leaving for overseas for my studies. They performed beautifully, excellent crisp loud bass. I'm sorry to sell them but I don't have the money to keep up with the car audio hobby anymore. If you need any other information re: specs or whatnot, shoot me a message. They haven't been used in a while, but I took them to a local caraudio store to have them tested to make sure they were in perfect running condition. I would like $250 or best offer, I originally paid around $350 each //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
