Thanks guys, Still lots more to come its just a slow process.

I will be doing a center console next with an ipad and maybe something in there for a little more midbass. Also redoing my doors with 6 crescendo 8in mids and 4 selenium super tweets per door. Current set up still isn't cutting it.

I metered it today on the 55 hundos with the extra batteries. Clamped between 8 and 9k at a few different frequencies. Voltage is staying above 12.5 now on a burp.

New scores quite surprised me, these amps seem to be performing much differently then the aq's. My peak frequency changed drastically and it's much louder on the low end. These numbers are on the dash driver door open.

51hz 156.6

41hz 157.9

39hz 158.1

37hz 157.1

35hz 156.7

27hz 156.0

25hz 155.9

22hz 154.0

20hz 152.3

Sealed up it still likes 51hz and did a 156 flat
