I bought them speakers about a month ago and I fix it about 2-3 weeks ago,I had before vibe slick 6-9,420 watts each but I hav 3500 watt JBL amp which is very powerful amp but vibe speakers was not enough for that amp so I thought to buy theses speakers coz it mentioned on the speakers 600watt power each so I decide to put them speakers in my car but I really disappointed after install theses speakers it my car.the sound of speakers is crap...it doesn’t give genuine sound ,...anyway I’ll not recommend to anyone to buy them .....
