Important installation considerations for using this amplifier.

Your CHAOS EXXTREME Class D amplifier is designed to run with a minimum load of 1 Ohm.

Operating the CX2500D or CX3500D with a speaker im- pedance load below 1 Ohm may result in poor sound qual- ity and damage to the amplifier circuitry. Such damage is not covered under the warranty for this product.

The fuse ratings for these amps is 40A (using two 20A fuses) for the CX2500D and 90A (using three 30A fuses) for the CX3500D. Although sufficient for normal working conditions, overloading the amp may result in blown fuses. Please try to avoid overloading the amp in this manner.

Don't misuse the level control!

Do not mistake the input level control for a volume control! It is designed ONLY to match the output level of your audio source to the input level of your amplifier.

Do not adjust this input level to maximum unless your input level requires it.

Ignoring these instructions will result in an input overload to the amplifier, and excessive audio distortion. It can also cause the protection circuit to engage.

Tips for making your system as safe as possible

When making electrical connections to the amplifier, please observe the following:

•Always use 4GA or heavier wire for power and ground connections.

•Wire the amplifier directly to the car battery. Make sure there is circuit protection (such as a fuse) on the positive power lead within 18” of the battery.

•When making a ground connection, always use the shortest possible wire to a good chassis ground point.

•Wire the remote turn-on connection to the remote turn-on lead of your EQ or head unit. In some cases, this may be the power antenna lead of the head unit.

•Fuses protect BOTH the amplifier and the electrical system of your vehicle from faulty conditions. If you must replace a fuse on the amplifier, you must use a fuse of exactly the same type and rating. A different type of fuse or rating may result in damage or cause a fire.

SHOCK HAZARD! Do not open the case

of this product. There are dangerous voltages present within the unit. There are no user-serviceable parts within the unit.
