Congratulations!

Thank you for choosing a Diamond Audio Technologies HEX amplier. We sincerely believe that HEX ampliers have the very best performance
and value. DAT products are engineered and produced with the highest quality materials and incorporate the latest technology. We think you
will nd your new HEX amplier meets or exceeds your expectations and provides excellent value.

Properly installed, your new HEX amplier will provide years of high quality sonic reproduction. Before installing the HEX amplier in your vehicle,
please read the entire manual carefully. It is required reading for the protection of your vehicle and for the maximum performance of your mobile
audio system. All HEX ampliers have been extensively tested and “burned-in” for maximum reliability. If after reading this manual, you still
have questions regarding this product, we recommend that you contact your authorized DAT dealer for expert installation assistance.

If you need assistance with repair or warranty, detailed warranty and return/repair information is listed in the back of this manual. Be sure you
record your serial number, model number and date of purchase for your HEX amplier as this will be necessary for any returns.

Please Practice Safe Sound!

Continuous exposure to sound pressure levels over 100 dB may cause permanent hearing loss. High powered mobile audio systems may produce
sound pressure levels well over 130dB. Use common sense and practice safe sound.
