Out with US Amps, in with Sundown

[bigjae1976 0]

Just swapped out my US Amps for some Sundown Audio amps. Sad to see the ol' faithful US Amps go, this was VERY hard to do. I must be a responsible sundown dealer and use the stuff that I sell. I did consider slapping a sundown sticker on the US Amp heatsinks.

Old install

I still have an Fi Q12 and the Sundown SAZ-1500D is my first ever class D amp. I metered at 140.5 db. Pretty damned good if you ask me for the bass eating BMW trunk. A 2.3db gain since I was metered using the sub brand new with a super stiff suspension.

Measured by a termlab in the pass side kick panel. Peak freq was 47hz. The reading might be a little higher since I was inside.

Electrical:

Stock 120 amp alt

Kinetik HC2400 battery

Used 2007 db drag racintg 45 hz test tone

Gains were all the way down which didn't matter since I was overpowering the sub.

This Fi Q sub is a beast. I've been driving this sub with a 2000 watt amp and now a 1500 watt amp. The only thing that happens is I start smelling glue when the coil heats up. Takes it like a champ with a responsible user.

I didn't get a voltage reading since the sub was getting pretty hot. Sometime later maybe.

What amps are coming out and what amps are going in?

US Amps gone and Sundown is in. I figured that it would be obvious since I'm posting in the sundown forum.

Ok..you got me.

Out:

USA-2000x

USA-400x

USA-200x

Fi Q12

(all of which are for sale)

In:

SAZ-1500D

SAX-100.4

AA Havoc 12

I would have shoehorned a 3000D in with another Havoc12 but I got so sick of installing 2 ft long US Amps with 4 power/gnd connection. I don't think I needed it anyways

Yeah, they make good stuff. Just gotta be careful with the wax...use too much and its like taking off dried peanut butter.
