Repair Diagnostic Service Gauranteed Satisfaction. Over 3 decades of experience repairing  car audio in Atlanta Ga. Not limited to HiFonics but this ad is for HiFonics - contact me for any other brands 


Generation  V, VI,VII, VIII, X ETC.....  


This ad is for initial diagnostic of repair and the $75 fee can be applied toward the repair total cost. Cost vary depending on extent of repair needs. (usually $85.00 to $300.00 total cost)  and again your diagnostic fee is subtracted from the total cost, so if total cost is $125.00 the diagnostic fee of $75.00 is subtracted leaving a balance of $50.00 due once repair is complete. Plus return shipping cost.

I use ORIGINAL EQUIPMENT MANUFACTURER  (OEM) parts and when unavailable I only use top quality parts like Onsemi, Nichicon, Panasonic, Fairchild etc..

This diagnostic fee covers 1 HiFonics amp up to 3000 watts. Let me know if you have a larger wattage amp. 
ALL COLOSSUS AMPS ARE MORE!! Even the earlier generation 1200 watt.
