They would sound the same.....Remember its the same sub "playing" @ the same ohmage.......... & dats Providing that u gona be playing one sub at a time.
hold up its two subs u have one dual 2 and the other half ohm x2 they should sound the same played together on the same amp but are u gonna run these subs series, or parallel @ half ohm?? make sure your amp can handle this low ohmage.
