Just installed 2 L7 15's powered by Memphis Mojo 2500. And also 2 Memphis MCA300's( one on each side of highs). Have a Kinetic under the hood(1800cca), 250amp alternator, and The Big 3 done with 1/0. But at it 2k rpms its still dropping to 12.4-12.6! All grounds were stripped to bare metal....can't figure it out...should I add a cap or maybe a battery?

Adding a battery will keep it from dropping from 12v 10v

makes me think your 250A alt really isn't...
