8ight Posted May 3, 2013 Report Share Posted May 3, 2013 Wow, that thing is badass. Super clean and tight all around. The output section is so simple and beautiful, and it looks like the windings on that transformer would just blow out if they were any tighter. All of that and they blow it with the cheap set-screw terminals where I would have much preferred a barrier strip. Under no circumstances should you be shoving bare wire into an expensive piece of equipment like that. Smexy amp you're lucky you got the chance to play with it much less pop the hood. I'm gonna hate Link to comment Share on other sites More sharing options...

I can't wait until he gets his next paycheck, he's getting a temporary set of speakers until he can get some real good components for his jeep I'm mad now because they were temporarily not available on crutchfield, but now it's back ( and not on sale anymore, full $800 now) so I'm guessing there isn't a newer model and they were just trying to kick start a sale or two because its had no prior reviews, hell I've only found a rare few results on google for pictures of it and an occasional german site that sells it summer time might be the time to attempt some good lawn work without college classes, maybe I can manage to nab one again for me also wondering what is a barrier strip because I've only seen the fork terminal setup and the set screw style on amps and here's the link for anyone interested in this amp http://www.crutchfield.com/p_975E400/Helix-E400.html?tp=115#overview-tab Link to comment Share on other sites More sharing options...
8ight Posted May 6, 2013 Report Share Posted May 6, 2013 I think you are thinking of a barrier strip when you say fork terminal. Terminate everything to spades and these terminals are your best friends. I'm gonna hate Link to comment Share on other sites More sharing options...
Nathan Daniel Galen Posted May 18, 2013 Author Report Share Posted May 18, 2013 oh well now I learned something new, I never knew what those were called, although I have 4 pairs of fork hook-ups for my speakers right now I'm actually surprised that they used through hole screws considering it's a speaker amp and in most cases wouldn't be bridged with it's already high power output it would have been cleaner looking and the wires are less likely to come loose ( as long as the crimps are well done, no great crimp is done without at least 2 squeezes) but I will say that I find the through hole more convient for bigger wire sizes 12 gauge and up Link to comment Share on other sites More sharing options...
