4000w RMS Mono Block Amplifier

Re•serve: [ri-zurv], verb (used with object): to set apart for a particular use, purpose, to withhold.

To kick off the entire IX Reserve series of mono block amps from IA, we have the killer IX4.1 Reserve.  For demanding installs that need serious power in a small space, but do not want to sacrifice quality, the IX4.1 is an outstanding option in the 4000 watt amp market.   At less than 13” long, the IX4.1 can get it done without taking up your whole trunk space.

Just because the IX4.1 is small in size, it is not small in features.  A flexible low pass crossover, as well as a flexible subsonic filter will keep your subs sounding great in their box without risking damage if tuning correctly.  We gave the IX4.1 the same easy strapping set up as its big brother the IX6.1.  With an onboard fan in addition to the IA Reserve amp input voltage meter, you know the IX4.1 will stay cool and protected during the most demanding times in the depth of summer.

The IX4.1, like the rest of the IX family, has a strong dampening factor and low signal to noise ratio,which will keep the sound under control and clean.  Despite its size, the IX4.1 has 1/0 power and ground connections, with 4 gauge speaker wire outputs.  These are all traits of large amplifiers that do bigtime power.  Put all of this together and you get one heck of an amplifier in a compact package.  The IX4.1 is the right choice for the demanding daily driver that has a high power sub, as well as the demo monsters that require a durable amp and don’t have loads of space to mess with.

Incriminator Audio's Splitforce Technology

USPTO #: US10076062B2

SplitForce divides the power supply section and the audio section into two halves and places them on top of each other in a vertical configuration, and uses link cables to attach the two sides together creating a working unit that can function like existing amplifiers, while both sides have their own PCB. The end result is an amplifier that is 50% smaller in length, while still maintaining the ability to strap or link amplifiers. The additional two inches in height allows space to add many extra features such as an onboard voltage display, remote indicator (REM-I) plug which allows you to monitor the status of your amplifier from another location such as the dash or podium of your vehicle, three extra cooling fans, segmented power and ground connections. This unit has all the features, function, and power you need on the streets or in the lanes.
