That's right... the big boy. I've been dying to get my hands on one of these so I jumped at the chance. I've owned several IA amps in the past and I'm a big fan. So, when I saw this thing on the interwebz, I got a little weak-kneed at the thought of huge, bulletproof power from a name like Incriminator. Let's get to work...
Incriminator Audio 80.1
2,400w @ 4ohm
4,800w @ 2ohm
9,600w @ 1ohm at 14.4v
Price- $2,699 (WooferWarehouse.com)
Overview shot. I just had to get another amp in this one so you can see just how small the footprint on this thing is. I think it's genius since 99% of installs are footprint restricted rather than height restricted.
Well... hopefully your install isn't height restricted because this monster ain't short. I didn't measure it, but IA says it's 5.11" tall. I could have sworn it was taller than that- It sure seems like it, but I guess that's because I'm used to 2" tall amps.
Output side is crazy clean. Those terminals are 4awg. They swallow up 8awg speaker wires.
The input side is a different story. It's busy as shit. First thing you'll notice is triple power and ground. And that they're grouped. I like that for some reason since all of my other amps alternate them and some even swap the location on you just to keep you on your toes.
Controls are as simple as they can be. And, IMO... as simple as they should be. Gain, SSF and LPF. That's it. Tip of the hat to IA there. You'll notice the port for the bass remote and two ports for "strapping/mirror". Another stroke of genius here in that you can theoretically "strap" an unlimited number of amps. I'm not sure if the cord is proprietary or not as it looks different than the remote port.
Next is the voltmeter. It's cool and all, but I just don't see a need for a voltmeter on my amp. I guess if you're trying to troubleshoot something it's nice to have it there, but the amp isn't likely to be in view while you're playing it and need to monitor voltage, so it's just a light show to me. It was also reading a couple tenths lower than every other meter we had on it, so you might want to check yours before you rely too heavily on it.
The voltmeter may not be accurate, but you see that little light that says, "clip"? That one is. And IA just saved you the price of a DD-1 because it was spot on with both scopes.
Here be the guts. As you can see... No, it's not just a pair of 40.1's stuffed into a single case like some people think and like other companies have done. They've just cracked a board in half and split up the input and output sides of the board. It's a true mono.
Okie dokie. Enough drooling. Let's see if this thing has as much go as it does show.
Setting it up unloaded. I'd have thought we'd see more voltage here, but whatev. We set it up with the scope and compared it to the onboard clip light. And honestly... you don't need either because the amp makes a hellacious buzzing when you get it into clipping. It also jumped up to ~ 125v. Usually you can maybe coax an amp into a soft clip, but this one was having none of it. It got pissed past this number.
Let me take this time to apologize for the lack of a scope under load in the following pics. Both scopes took a dive on me... or the amp murdered them. I'm not sure, but either way, I was scope-less after the setting of it. And I'm ok with that. Most people will set it up with a DD-1 or use the onboard clip light and let it eat so this is pretty real world. Would have been nice to see what was going on under load though. Oh well. Shit happens.
First up is 2.5ohms resistive. I hate to have to remind you guys of this every time, but this is like the AD-1 Amp Dyno. There's no rise and the voltage and amperage are in phase here.
That's 3,600w @ 2.5ohms resistive and 13.7v. With an impressive 84% efficiency.
1 ohm resistive.
7,225w @ 1ohm resistive and 13.5v. Efficiency drops to 72% here. That's not uncommon.
First up is .5 nominal with nasty rise.
4,200w clamped rising to 2 ohms dropping to 13.4v.
8,440w clamped rising to .65 ohms dropping to 13.1v.
Rated 4,800w @ 2. Did 3,600w @ 2.5 resistive and 4,200w clamped @ 2.
Rated 9,600W @ 1 & 14.4v. Did 7,225w @ 1 resistive & 13.5v and clamped 8,440 @ .6 & 13.1v.
I hate to say it... but even if you give it the extra volt it's rated at, it still falls short of rated. By quite a bit. That's surprising. And quite frankly... disappointing. The electrical it was tested on is just about best case scenario for a 12v system. Unless you happen to have triple alts or better, I guess.
Could I have played with the gain to try to get rail voltage back to 96v under load? I suppose. But I don't give the other amps I test that luxury and most of them seem to have no trouble doing their power. And honestly, at this price point... should I have to?
Bottom line... I can't give this amp a pass. But the book isn't closed on it yet as I can just hear some of you yelling that it's a high voltage amp and not "made" for 12v (even though IA lists 12v ratings). I'm going to get some higher voltage testing done on it, but unless something magical happens between 13v and 16v, I can't imagine it's going to change my mind.
