MA1000.4 Beyond Belief

The new MA series, available in both 4ch, 2ch and 1ch sets a new standard.
Looks, performance, features, dimensions and marine capable* makes the MA series highly potent.

The 1000.4 refers to 1000 watts divided into 4 channels, making it a key component in any installation, either large or small.
With the ability to bridge the channels, the output is sufficient to forcefully drive our EL and IS subwoofers in addition to a set (or more) of speakers on the remaining 2 channels.
If the application is made for speakers only, 4 x 250 watt @ 2 ohm gives you sufficient headroom to add multiple speakers without lacking power.

The small footprint even makes it possible to install the amplifier in nearly any application. Efficiency is never a problem due to the full range class D design, fear not, it is still capable of SQL as we have used premium components in both pre and output stages in the amplifier.

Advanced crossovers with our «ACCU8» function (individual click position for corresponding frequencies), gone are the worries about how to adjust your amplifier best possible.
Impressive crossovers spanning all the way from 15 Hz to 6000 Hz, makes it possible to run tweeters directly of the MA1000.4,
however with the immense output better beware of the dangers it may present, both to your hearing and the tweeter itself.

In addition, the crossovers offers full range, highpass and lowpass on all channels and it even has bandpass for the more demanding end users.
In case of clipping or driving the amplifier beyond its limits, the built in clip function will automatically adjust the output till the signal is clean, which is way better than burnt voice coils.
Should your desire be power-sports, atv’s or marine application, the MA1000.4 is marine capable**.
