IN my case and probably the OP's case he wants to wire to .5 ohm to get more power and to be able to use a quality brand amp.
I've got dual 2 ohm sa-12's and to get more power than my 2 ohm stable only 1200 watt amps has I need to upgrade. Today most of the good amps
Put out maximum power at 1 ohm. So running a 1500-2000 watt amp at .5 ohm to receive the power I need makes more sense than getting a 3500-4000 watt
watt amp at 2 ohm. Either way your going to need to boost your electrical and it seems like such a waste of amp to run 2 ohm not to mention your paying twice the money usually to only use half of what you pay for.
Seeing as people are doing this on a regular basis in large numbers nowadays I don't see why it can't be done if done correctly. Heck crescendo will warranty their amps at .5 ohm for $75 more
Wish sundown did this also
