im about buy two L7 solobaric 15's and was wondering should i get the 4ohm version or 2 ohm version because im running them on a pioneer 5000spl amp thats only 2hm stable?
If your amp is 2 ohm stable, then buy the 2 ohm subs (assuming they are dual voice coil). That way you can wire both subs to a 2 ohm total load. By using 4 ohm dual voice coil subs, you would only be able to achieve a 1 ohm or 4 ohm total load.
