i wans reading car audio mag and some guy had a 10w7 wired in 4 ohm ( or could even be 2 0hm) with a pdx1000.1 now those amps can be run in 4ohm or 2 ohm not 3 ohm soo im confused on how jl subs work with other amps....
Any amp that is 2 ohm stable can be run at 3 ohms. You simply take half of the amount of difference in watts between its 2 and 4 ohm ratings to get what power you will see at 3ohms.
