Should I get the DSC4125 over this amp?

Someone on diyma tested the 175.4 and it only did 120 per channel, if I remember correctly.

There was a quote from it in the big ol' thread that tspence has over there about the 175.4 and trying to figure out if it was class d or a/b. It did like 123 or something like that before distortion levels got too high.

edit:

"He said he put it on the bench and the specs for continuous unclipped wattage per channel are as follows:

14v = 128-watts

13v = 111-watts

12v = 95 watts "

like is said the dsc was the way go, clean a/b sound that puts out rated

Lots of (refurb'd) power for cheap... - DIYMA.com

Looks like it doesn't perform as expected.

I just finished reading that thread. I think they agreed it was class-A/B.

Not to mention that the people who were contacted at PA about this amp said that it was class a/b and not d.

I have 2 4125s running all my 16 mids and 16 tweets.

Well its kind of too late now for everyone to become an expert on the PA amp now. I'll try to send it back for refund.

Give me the link cause I don't see it? I see everyone saying it did at least 140 x 4 @ 4ohm.

mb since its a/b much cleaner sound, class d amps are not clean and i have not heard a good full range class d except zed audio

Uhhh Alpine PDX amplifiers are all Class D. They sound amazing.

If you are over heating one then you are doing it wrong, I ran a 150.2 in a enclosed amp rack and it never got hot.

pdx's have noise probloms its a known fact, i do not like the way they sound but hey its all opinion so. i have seen many pdx 1000.1 overheat, i listened to the pdx 4.100, for 250 dollars there are a lot of other amps id rather get. ???

Probably from idiots trying to run it at 1ohm.

Again I had a 600.1 ran it at 2ohm never got hot, warm yes but never hot to the point of thermal shutdown.

Those BB amplifiers are pretty nice, The Quart is alright my biggest gripe about it is its a single side traced board VS the BB that is dual side traced board. Meanding that the Quart will have a higher failure rate due to vibration and heat.

Not all Maxxsonics amplifier are like that but alot of them are. Mostly the Hifonics and the newer Autotek stuff.

Sure there might be better amplifiers for the price but you do get what you pay for.

i would much rather get an old school us amps or zed audio based 4 channel 2 be honest. you can get audioque's 4 channel for 229

Cadence Ai4 is the same as the Que both of them are quality built and stout powersupplies too.
