It's better to have too much power available than not enough. Just turn down the gain.
I thought Alpine was a decent amp, and it is, untilI bought an Art Series Precision Power amp to replace it. I couldn't believe the difference just an amp can make. And it was a straight up swap of one 25x4 watt amp for another 25x4 watt amp. Blew me away. I only buy PPI amps, and I only buy old school PPI amps ('97-'02), not the hideous newer ones made by DEI.
If you buy that older JL amp, make sure the terminal screw heads aern't stripped. JL used allen head screws in their amps in the beginning. They came out for the first time in '01 or '02.
