What's the difference between these amps?

The old school blue Jensen amps from the late 80's and early 90's were great amps. I had a little 80-watt jobber back in the early 90's that was driving 2 8" Punch subs! Those were the days //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif The Mb Quart Discus line are good quality budget amps. I have the DSC1500.1D and its a pretty decent amp, especially for the money.

From the CEA2006 web site,

Primary Output Power should, according to CEA2006, be measured with 14.4V DC supply, a 4-ohm load and with 1% or less total harmonic distortion in the output. Other specifications included in the standard involve different impedances and supply voltages. This is where the manufacturer can indicate the conditions which make their amplifier perform optimally.

Can anyone on here tell the difference between 1% or less total harmonic distortion??? I sure cant and Ive been into audio for a long time. Want more headroom? Buy two and bridge'um Just a thought.

As soon as you bridge them I can promise you that they will run hotter than hell and the THD will go through the ceiling. That one you'll be able to hear unless your speakers are total junk. The main difference in price between the Kicker and Jensen is the quality of components used in the construction and the level of quality control coming from the factory. There are plenty of other things the CEA 2006 doesn't address, such as bandwidth, signal to noise and THD at frequencies other than 1kHz. A lot of budget amps sound harsh at higher freqs and begin to roll off well before reaching the top end of the audible spectrum.

One final thing, CEA 2006 compliance is voluntary. There is no independent testing involved.
