The all new Incriminator Audio IX3.4 is the new answer to compact, premium 4 channel amplifiers. All the features of the outstanding IA 3.4 but with more power and less size, updated to the new IX series standards. When we say compact, we are not joking around. The new IX3.4 is trimmed down to a miniscule footprint of less than 8”. That saves you space but doesn’t cut down on the traditional high quality build we are known for in our world famous amps.

One thing you don’t have to worry about is the crossovers, as we still have the same level of flexibility in the crossover network our customers have come to expect from our multi-channel amplifiers. Which means, you will have high-pass / full range / low-pass crossover settings for both pairs of channels, as well as subsonic filter.

We didn’t stop at the size, why not improve the power too? That is exactly what we did, by bumping up the power on the IX3.4 to 100 watts x 4 channels at 4 ohm and 340 watts x 2 at 4 ohms. The great news is the new Class-D design is very efficient and very low distortion, so you will only need a mere 50 amps of fusing for the all new IX3.4 while hearing all the right notes.
