Love those old US amps, i ran PPI and Rockford but my buddy ran a 75x2 US on 2 JL 10w1's and sounded great. His mustang was more SQ but it hit 132 in a sealed box.
Dereck, I've noticed this tool will also show you box tuning but I have seen any videos of someone doing it with this tool.. only seen videos of the smd im-sg finding enclosure tuning. can you tell me how this one does it?
Would be really neat if someone did full power/factor curves (~.5-8 ohms @ .01%, 1%, 10%, clipping) on a couple similar amps to look into why some amps are "louder" to ear but not necessarily to number.. but then you might need to do some work on dampening factors as well I guess.
id love to have that but i just cant bring myself to drop 500 bucks on it since im just a hobbyist. is the price really justified? i really don't see why it is that much other than a supply and demand kind of thing.

Love the old "play into a dead short" amps.

I'm waiting eagerly to see that test run!!
That smd is awesome! wow 4.7 is very high which is amazing for what this amp is supposed to put out at a lower "4ohm".

Awesome video derek I need to get 1 of those AMM-1. $??
Does that power supply run on diesel? 😄 That thing is loud!
Another good video!
This is going to be interesting.

Awesome amp!
Wonder how come my amm-1 don't have live power ?? Any idea why?
Check with D'Amore Engineering?
That is s a mono load, correct? Also how do you set your gains when you use the amp dyno and the amm,-1?
You can use the dd1 to set gains accurately.
That's a nice amp. & I like that f50 in the background
I will enjoy the full test on this one. Thank You. 👍
lmao true 50 watts
Lol does rated!
Come on! Stop torturing us!!
