The Importance of Pre-Planning

This section focuses on some of the considerations for installing your new HEX amplifier. Pre-planning your audio system layout and best wiring routes will save installation time. When deciding on the layout of your new components, be sure that each component will be easily accessible for making adjustments.

CAUTION: lf you feel unsure about installing this system yourself, have it installed by a qualified technician.

CAUTION: Before installation, disconnect the negative (-) battery terminal to prevent damage to the unit, fire and/or possible injury.

Before beginning any installation, follow these sensible guidelines:

1)Be sure to carefully read and understand the instructions before attempting to install the amplifier. The instructions can only help you make the installation successful.

2)For safety, disconnect the negative lead from the battery prior to beginning the installation. It will keep any unintended short circuits from damaging vehicle electronics during installation of the amplifier.

3)For easier assembly, run all wires prior to mounting your amplifier in place.

4)Route all of the RCA cables close together and away from any high current wires or vehicle com- puters. This will greatly minimize the chances of unwanted noise.

5)Use high quality connectors for a reliable installation and to minimize signal or power loss.

6)Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines, or electrical wiring when working on any vehicle.

7)Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection.

8)Avoid running wires over or through sharp edges. ALWAYS use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.

9)ALWAYS protect the battery and electrical system from damage with proper fusing. Install the ap- propriate fuse holder and fuse on the +12V power wire within 18 inches (45.7 mm) of the positive battery terminal. This is for protection of the wire running through the vehicle.

10)When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean ground connection. Grounding connections should be as short as possible, yet be adequately connected to metal that is welded to the main body, or chassis of the vehicle. Do not use seat bolts, trunk hinges, or poorly joined metal for grounding points.

HA 750.1, HA 700.2, HA 700.4 specifications

Diamond Audio Technology has established itself as a key player in the high-performance audio industry, particularly known for its innovative amplifiers. The Diamond Audio HA series, encompassing the HA 700.4, HA 750.1, and HA 700.2 models, is designed for audiophiles who demand top-notch sound quality and reliability.

The HA 700.4 is a robust four-channel amplifier that delivers an impressive 100 watts RMS per channel at 4 ohms, while producing an astonishing 200 watts RMS per channel at 2 ohms. This amplifier employs advanced Class A/B circuitry, ensuring that audio reproduction is both powerful and crystal clear. It is equipped with high-level inputs, making it versatile enough to integrate with factory-installed audio systems. The HA 700.4 features a variable crossover, which allows users to tailor the output to suit specific audio preferences and achieve a balanced soundscape.

Next in the series, we have the HA 750.1, a mono amplifier capable of producing up to 750 watts RMS at 1 ohm. This model is designed for enthusiasts seeking strong bass performance. Its powerful output is complemented by a low-pass filter, enabling users to optimize their subwoofer performance. The HA 750.1 utilizes a high-performance MOSFET power supply, which ensures efficient power delivery and minimizes distortion, resulting in deep, rich bass tones.

Completing the lineup is the HA 700.2, a versatile two-channel amplifier that delivers 110 watts RMS per channel at 4 ohms and 220 watts RMS at 2 ohms. Ideal for driving component speakers or smaller subwoofers, the HA 700.2 features similar Class A/B technology as its counterparts. Its compact design is perfect for installation in tighter spaces while maintaining thermal efficiency through built-in heat sinks.

All three amplifiers are designed with durability in mind, featuring heavy-duty aluminum chassis that resist corrosion and provide excellent heat dissipation. The inclusion of adjustable gain control and built-in protection circuits further ensures reliability and longevity under various operating conditions.

In summary, the Diamond Audio Technology HA 700.4, HA 750.1, and HA 700.2 amplifiers boast state-of-the-art technologies, robust outputs, and user-friendly features that cater to serious music lovers. Whether enhancing high-frequency details or delivering deep bass, these amplifiers provide an unparalleled audio experience, making them a worthy addition to any sound system.
