Ok got the amp in last night and man talk about little guy for such a power house. It is sitting under my drivers seat at the moment since my better half made some plans for us that I didn't know about so pics of install just aren't going to happen. Ok now on to the initial thoughts.
1. Gains are setup in a 1,2 channel and 3,4 channel. This was a bit odd to me since the sk85.4 was setup as a 1,3 and 2,4, so I had to switch RCA's and speakers around a bit.
2. It is small and I mean small for the power. It is literally half the size of the SK85.4 where that one I had to finagle in and out from under the seat, this one not a problem at all.
3. Fit and finish of the amp is everything you would expect from a $400.00+ amp. Flat black which I love but does show the oil off your fingers pretty easily. Everything is marked clearly and no signs of markings being rubbed off like some of the old equipment we have all used in the past.
4. Xovers- this is kinda neat there is a 1x-10x switch that allow you to use the same xover for sub frequencies and high frequencies. Not sure how many other amps do that but I thought it was cool since its the first time I have gotten to see it.
5. Wiring- Now if you have actual 4 awg wire like I do it doesn't all fit into the 4awg power and ground, seemed little goofy might just have to spend more time with wire management to get it all to fit. Speaker wire, it handled my 12awg no problems at all and looks like you could almost get 8awg in the terminals. Terminal, they are great easy screw in and out allens with no signs that I would ever be able to strip them out with the supplied allen wrench.
6. Sound- Now this was interesting to me, I set the gains and haven't changed my xover points in my headunit but after listening to it for a few minutes last night it seems that it has brought the highs out in my system. So there will need to be a tuning session here soon. The mids were incredible sounding from low volume all the way up to where it can make your ears bleed. They sounded much more full at lower volumes and even with the extra power they held their composure in the higher volume range. I don't know if I will be adjusting them much but we will see.
At this time I am pretty happy with the amplifier and for short listening period I can say that I will be keeping this one for the foreseeable future. Pics are coming I have to transfer them from my dumb-phone to my computer. Thanks for reading guys. I will have more in the future with what I am going to do with my substage.
