[. . . ] Due to their size the crossovers should be mounted in the trunk of the car. We recommend the connection to a 4-channel amplifier, because it provides more possibilities of fine-tuning. Should the system be used with a 2-channel amplifier we recommend bi-wiring. The speakers of the system can be adjusted to your individual listening habits by repositioning the jumpers J1, J2 and J3. Please make sure to turn off the entire system before changing the jumper positions. function of jumper J1: 4- or 2 ohms mode Jumper J1 adjusts the crossover to the so called 4- or 2 ohms mode. The basic adjustment (ex works) is the 4 ohms mode which means that only one pair of woofers is used in the vehicle. When using two additional BRAX Matrix mid/bass speakers as a double bass system on each side, e. In custom made door panels, the jumpers J1 must be removed and fixed into the 2 ohms position (see fig. Function of jumper J2 and J3: Mid level and tweeter level adjustment Jumpers J2 and J3 are used for the individual adjustment of the mid- and tweeter level (adjustment of levels of these speakers in relation to the level of the bass). In the 0 dB-position (ex works) the mid- range and the tweeter play at the same level as the woofer. This should be basis of your fine tuning. Depending on the placement of the chassis and your individual listening habits the levels of the midrange and the tweeter can be raised or lowered by changing the position of jumpers J2 and J3. Please make sure that changes in the position of the jumpers J1, J2 and J3 must always be made simultaneously for the right and the left channel on both crossovers.

This ensures that each speaker is provided with an optimum signal and that occasional power fluctuations are eliminated.
