Proper installation guarantees better performance, follow these suggestions for installation.

- Only use shielded cables to connect the audio signal between the car radio and the amplifier, it is not necessary to use very expensive cables, but do NOT use very bad cables!

- The use of good quality RCA connectors guarantees a good contact, lasting over time
and reliable even after several operations of insertion and disarming.

- Shielded cables must be kept at a minimum distance of 10cm c.a. from any generators of car noise, such as power units, pumps, cables, etc.

- For power connections use only good cables, of suitable sections and protected in the engine compartment. The cables for car-audio applications are very flexible and therefore easy to install.

- Carefully take care of the laying of the cables and operate in order to follow different routes to signal cables from power cables.

- It is a good idea that the mass of the amplifiers is connected to the same point, together with the car radio's one.

Example: if there are two amplifiers in the trunk, find a good grounding point for the amplifiers themselves and bring the mass of the car radio to the same point using a cable ( 3-5mm).

- Fix the amplifier securely, to avoid its movement and then the cables jostling.

- A well-designed and equipped system may involve the collection of various devices, if this happens, ensure adequate ventilation of the place where the amplifiers are installed, perhaps with the aid of an additional forced air flow by a fan inside the various compartments.
