Besides the extra flexibility in the wiring configuration and more power handling / sub, are there any real sound quality differences between a single and dual voice coil subwoofer? I recently blew my DVC sub (JL 10w6v2) and i have a chance to get really good deal on another sub but it's single a voice coil. It's a 4 ohm single while the i had the JL sub configered for 2 ohm. It is going to be powered by a JL 250/1 amp and since this amp puts out the same power between 1.5 and 4 ohm, will i be putting the same amount of power into a single voice coil sub if i just turn up the amplifier gain? I hope i worded all this right, please let me know thanks.
