yep I believe so but either way I would change them as they used to crackle at certains pitchs with even my baby 12" fli amp and sub! If you wanna stick to sony be prepared to pay a fair bit but yes longer lasting. I have used mainly kenwood stereo, apline or what I have now pioneer f900bt HU which makes a HUGE difference, changed my cabling for the sound and not bothered with an amp or sub just yet and blimey what a sound! Surround sound esp when watching James bond dvd in the car woohoo!
