Cadence rep told me their first series of amplifiers had some serious design issues, but the recent models are a big improvement.. hmn.

Hmm, yea I know they use some kind of mylar stuff, but never heard of it affecting the dampening performance of it, hmmm. I've had the opposite when deadening doors with the edead stuff, its done a good job.

ttomczak: Does anyone have an opinion or knowledge of this amp?

Rockford Fosgate 5-channel Power 1000???

Sorry can't say anything about this, never used one, or even heard one and haven't even heard anything about that one on other sites

I guess I would have to wonder about a 25 to life model
The Power 1000, with 1400watts and 5 channels, listing for 1600.00 and seeing it selling for 500.00.

Not something unexpected from him. Remember, he isn't exactly unbiased. The price-points Cadence shoots for and the lack of meaningful info on their site makes Cadence highly questionable, improved or not.

If it's 1/2 as good as their original Power1000, it is a great amp. If you can get it for $500, then I wouldn't wait any longer.

Amazon has it for 509.95 with no tax and free shipping...

At least its something to think about, as well as the other 2 alternatives...

It means absolutely nothing to rate an amp at X watts into 4 ohms at 13.8 volts. We have no idea if that's at 0.5% THD, 1% of 10%. All it says is "minimum THD < 0.05%." That's meaningless. Is it continuous? Is it music power? No mention of the output at that THD. No mention of why their amps fail to double (or at least nearly double) their rated power into halved impedance. That goes back to the distortion issue. We don't know what the THD is at 4 ohms, so that 2 ohm rating is meaningless as well. The damping factor is too low (well, it's mediocre). No mention of slew rate, input impedance, output impedance, max current capability, power supply efficiency or output device design.

Any company that bills itself as "Consistently Louder! Consistently Harder!" I find difficult to take seriously. They remind me of the days when companies sold under-dash boosters that claimed 300wX2.

A _lot_ of amp companies, respected high end ones too, leave a lot of that information out.

Probably part of the reason for CEA... But rating at 14.4v



I'd imagine the THD rating is at the rated RMS power. But why would they call it "minimum thd" ... minimum distortion? That DOES look odd.

Damping factor is 200... 200 is better than Zapco Reference series...

The factual omissions by themselves aren't the problem, although you'll tend to see more specs from more reputable companies, but you're right, not all these specs.. It's the whole package with this company, from their marketing style to their utter lack of information and pathetic reliability history. IMO, a company should police itself. Just because the industry specs allow them to get away with it has nothing to do with whether it's a reputable thing to do or not.

Don't interpret this as a defense of eD. It's certainly not since I know virtually nothing first-hand about their amps. That said, I will not have a kind word about companies like Cadence.

We don't know how the damping factor was measured, so that's irrelevant too, unfortunately.

True. That's true with a lot of specs too...

Like Phoenix Gold's amps are rated in max... got to dig a little to find out.

I'm not so sure about that new cadence 5 channel now.. Might stick with my trusty ARC amp duo this time around.

I did quite a bit of work for a local shop several years ago. Mostly higher end (not comp cars) installs in more expensive vehicles. These customers were the more discriminating types. The shop sold PG, Alpine, Sony, Cadence, RF, ID, Infinity, and Pioneer for the most part.

It was my experience that the Cadence components were crap. Cadence was absolutely the bottom of the barrel compared to other components the shop had. Everything had noisy pots, cheap switches and poorly mounted barrier strips. Invariably, the Cadence stuff would come back for repair for issues like these. The amps were certainly cheap power in a small footprint, but at a cost. They had terrible control over drivers (poor damping factor), made nowhere near the power of some other similarly-rated amps, and IMO looked like hell (unless you're 19 years old and have a thing for neon and mirrors in your trunk, with 20" spinners on a 10 year-old rusting hulk). The stuff was garbage.

In the mean time, RF, PG and Alpine to some extent have certainly dropped from what I would consider quality components (the Best-Buy factor), and it's certainly possible that Cadence improved. However, looking at the ways they spec their amps, their prices and their sales pitch tells me that's unlikely. If ground-pounding is your thing, have at it. If you want quality and the best from good speakers, look elsewhere.

The bottom line was this: when a customer dropped the $ for a moderately expensive install, it was embarrassing when the car came back because an amp failed. This became routine with Cadence. The shop ended up only selling them off the shelf to kids who knew what they wanted before they walked in the door and planned on self-installs. Anyone who was paying for a nice clean install with above-average components got the PG or RF amps because they sounded very good and we could count on them.
Wow. This hasn't been my experiance at all with my Cadance M4000 amp, I must just be lucky.

Yeah, you've been lucky.

On another note, I gotta say, those wheels on the car in your avatar look damn good. Nice combination.
