None . .

After my original amplifier drove me nuts with an intermittent left channel. I dusted this beast off after retirement because the cooling fan was rubbing, replaced it and custom painted the lid to match my 14 tundra. This thing brought clarity and control to the high end and after some tuning the sub amp was pushing 2 12" shallow mount JLs to a clean and comfortable level from the factory head unit. Already loving it, I went one step further and dusted off a kinetic AGM battery and took advantage of the "eternal capacitor" posts. Not sure if it would stay charged,, im happy to report ts been 6 months and the AGM is still fully charged! And the "on board AGM improves the bass clarity beyond measure! You would never believe that a 400 watt amp is driving those subs!

The only weakness after maybe 15 years of use, is the cooling fan rubbing which is made by a completely different company. Easily replaceable with 2 snips of a red and black wire. Its large, but may have the same footprint as 2 amps and slimmer than most. You may never use the 5th channel lol

Everything!

Nothing!

Soo, this is Matt who wrote the original review for this amp back in 2007. It's 2012 and I still have this amp and have used it in EVERY car I've owned since 2004. It still looks amazing and sounds just as good as it did the day I bought it. I've used a lot of combo's speaker-wise and head units since and this thing truly makes a car stereo sound right. I highly recommend this amplifier, if you can find one.

Easy to adjust settings.Powerful,sounds great with the two 15"s i have hooked up with it.(rockford fosgate 15" punch dvcs).Doesnt heat up at all,and have not had one problem with the amp.

I suggest anyone who may be offered the chance to buy one,take it up.You won't be sorry.As the other review says,you can hook up different setups that sound nice with it.It can definatley handle it without problems.

Everything about it! 100Watts RMS @ 4 ohms x 5 + 400Watts RMS @ 2 Ohms x 1. You will never need to add anything else. This amp does it all, in style!!!

VERY LOW TOTAL HARMONIC DISTORTION(THD)!!!!

It's 20 inches long and 10 inches wide and may be hard to place without customizing the interior of your car.

I bought this 6 channel amp 3 years ago and have loved it entirely. I have done research on amplifiers and car stereos for many years, and fully believe this amp should be rated highest among 6 channels. This amplifier is recommended to those who want full surround sound in your ride, whether you have the center output on your head unit or not. The side of the amp reads "DTS" and has rca inputs for front L/R, rear L/R, Center, and Sub. If you don't have the center output on your head unit, the amp crossover side has a switch (full/Phantom) which creates a signal generated by the front L/R to immitate a center channel. If you were to compare this to modern home theaters it would be the equivalence of Dolby Surround II (Music). Along with great crossover features and superior amplifier internal components this z6000 allows the user to tune to some crystal clear high powered sound. Among the vast features, my favorite feature is the input (+,-) for an external capacitor which gives the internal mosfets a direct path to the power's reserve tank. This allows the amp to be running at full 14.4 volts at all times. My second fav is the fact that this z6000 has an internal cooling fan which is placed right over the amps mosfets.
My setup consisted of the Z6000cf, 1.5 farad capacitor, Panasonic CQ-DVR909U head unit, Kicker Resolution RS4 in front, RS6 in the back, RS3 as the center, and an L712D Solo Baric as the sub. All of which connected to the Z6000!! Amazing! With a Linkin Park DVD-Audio in the deck the sound was flawless!!! It almost brings tears to the eyes.
