ive yet to see a JL amp hit what is says it hits. you want best amp on the market, go buy yourself an A/D/S its quite possibly the dirtiest amp you can find. why would you want to buy a dirty amp? simple... these amps are considered dirty because unlike almost every other amp on the market, what it says it pushes for power, it actually pushes for power. so if you buy something at 1000 watts, thats exactly what you get, not 850.
