sundown 1500 with a regular wet cell under the hood and a stinger spv33 in the trunk, single run of 1/0 and 1/0 big 3. i dont know about voltage drops with this amp but with the old soundstream 1500w i had it dropped into the 11's but that was before the big 3 and i also was using distro blocks back then. the dimming isnt as bad with the sundown for some reason even though its a little more powerfull and draws more amps.
