Congratulations!
Thank you for choosing a Diamond Audio Technologies D3 Series amplier. We sincerely believe that DAT products offer you outstanding 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 DAT amplier meets or exceeds your expectations and provides excellent value.
Properly installed, your new DAT D3 Series amplier will provide years of high quality sonic reproduction. Before installing the DAT amplier 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 DAT ampliers 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 DAT amplier 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.
