I purchased one of these DSC4125 the other day for $119 at car audio deals and it actually shipped and arrived.
I cant currently comment on its functionality other than it works as I just installed it last night and only powered it up to make sure it works.
My comments regarding install are mostly negative...
The exterior of the amp looks good and all of the connections look good and sturdy.
(-) #1- The lettering next to the switches is dark grey over a black background which makes it rather hard to see what you are doing.
(-) #2- Nowhere on the inputs or outputs are "Left" and "Right" designated. NO L and R marked on any channel.
(-) #3 - The knobs are recessed and have an X inprinted on them so if you have a friend that has this amp and wants you to look at his system to see if it set up correctly, you CANT tell tell where the settings are unless you actually turn the knobs.
(-) #4 - The manual says that the FREQUENCY RANGE is 10hz to 1.2khz. What the hell is up with that?
I hope the internals are more well thought out than the externals! We'll see this weekend.
UPDATE: 7/1/2009
I have had a chance to fool around with DSC4125 for a couple of hours so far and as far as performance it seems to work pretty good.
I do not have much to compare it to but it sounds good and it puts out enough power bridged to get my DIYMA r12 really moving. The other two channels are going to the 6.5 PPI door speakers with gain at less than 1/2.
The amp does get pretty hot but it never got hot enough(80 degrees) to go into protect. I guess class a/b amps tend to get hot because the last a/b I had got rather hot as well. The filters and crossovers seem to work fine.
The amp does have the option of adding a bass knob however the bass knob controls the bass eq which adjusts 45hz from 0-9. I think I would prefer for the bass knob to be merely a level control for the sub.
So far, other than the negatives listed above, for the money, this seems like a very good amp.
I would like to take some gut pics but it would void the warranty if I break the seal.
