Yes Brazilian amps don't like 15+ volts. They makes their rated power at 12.6 volts.
My 10k is rated 10k at 12.6 volts. At 13.8 its rated 12,000 rms.
The horns are stupid loud. They are crossed at 2k and sound pretty good. Deff not an SQ setup horn. Just a stupid loud setup. Last show had a couple PRV demo vehicles and the Mclaren van. They were nasty.
PRV and Mclaren on two opposite sides of the huge field and playing with each other. It was amazing how loud they are with mid bass as well.
My Taramps HD3000 should be here next week. Will be running it at 2ohms on the 4 10"s until I get 4 more 10"s for the trunk lid. Does 3600rms at 1ohm and 2400 at 2ohms.
Almost done with the doors.
