BEST THING ABOUT THIS REPAIR SERVICE: After repair you don't need any coding, it will be plug and play, BECAUSE WE PRESERVE FLASH MEMORY WHICH CONTAINS DATA ABOUT YOUR CAR (MODEL, VIN, P/N). DID YOU KNOW DEALER WILL NOT CODE USED PARTS??? WE INSTALL NEW PARTS AND IF NOT WATER *BADLY DAMAGED IT SHOULD EASILY LAST ANOTHER 1-5 YEARS.

Q&A:

1. HOW DOES IT WORK?

• SIMPLE. YOU REMOVE YOUR AMPLIFIER AND SEND (FITS REALLY WELL INTO USPS FLAT RATE MEDIUM PRIORITY BOX 12$) IT TO US, IT TAKES 1-2 DAYS PLUS SHIPPING 2-3 DAYS MAX:
  BEST AND FASTEST WAY TO SEND IT HERE IF YOU ARE FAR AWAY:
  

2. HOW DO I KNOW IF MY AMP IS BAD?

• -BASED ON THE SYMPTOMS AND DIAGNOSTICS. USUALLY NO SOUND MEANS AMP FAILED OR IF SPEAKERS DON'T SOUND RIGHT. IF WE GET YOUR AMP AND IT APPEARS ITS IN GOOD SHAPE WE ONLY CHARGE 50$ DIAGNOSTICS FEE. MAKE SURE SYSTEM WORKS WITH AMP BYPASSED- THIS IS BEST EASY DIAGNOSTICS WITH BYPASS JUMPER (LOLLIPOP LOOKING JUMPER). USUALLY IF YOU SEE YELLOW AND RED LED IN THE BACK OF THE AMP (LOOK INSIDE) STEADY ON, BUT NO SOUND- IT MEANS AMP IS BAD OR NOT CODED CORRECTLY. IF YELLOW LED IS BLINKING, BUT RED IS ON, IT MEANS NEXT UNIT IS BAD OR FIBER OPTIC LINE DISTURBED SOMEWHERE BEFORE HEAD UNIT. IF YELLOW LED IS NOT, BUT YOU CAN SEE RED LED INSIDE BLINKING OR STEADY ON, IT MEANS AMP FAILED. OF COURSE YOU CAN GO AND SEE A DEALER TO DIAGNOSE 300-400$, BUT BELIEVE ME THEY MAKE MISTAKES OFTEN TOO!
  

3. DO YOU TEST THEM?

• -YES WE STRESS TEST ALL THE AMPS PRIOR TO SENDING BACK

4.WILL IT LAST?

• -YES IT SHOULD LAST SIMILAR TO BRAND NEW AMP, BECAUSE WE INSTALL ORIGINAL OEM PARTS. CHECK OUR REVIEWS, WE REPAIRED 400+ AMPS SINCE 2011.

5. I FOUND "CHEAP" AMP, CAN I JUST BUY USED AMP FROM JUNK YARD OR EBAY?? WHY TO REPAIR MINE???

• -YES AND NO: IF YOU FIND THE SAME MODEL AND WITHOUT CCC OR CIC, IT MIGHT WORK, BUT IF YOUR CAR EQUIPPED WITH NAVIGATION CCC OR CIC, MOST LIKELY YOU WILL GET NO SOUND EVEN WITH WORKING AMPLIFIER, THAT'S WHY ITS BETTER TO REBUILD YOUR ORIGINAL AND ENJOY PLUG&PLAY SETUP. CODING IS NOT THAT SIMPLE AN MIGHT COST YOU 100-500$ JUST TO PROGRAM IT. USED AMPLIFIERS DO NOT COME WITH REAL 1 YEAR WARRANTY, SO CHANCES IT MIGHT FAIL SOON ARE HIGH.IN REALITY ANY AMPLIFIER MUST BE CODED TO THE CAR TO AVOID GLITCHES. FOR EXAMPLE IF YOU BUY E64 AMP AND INSTALL IT INTO E90 CAR YOU WILL LOSE REAR SPEAKER CHANNELS AND IT WILL NOT SOUND CORRECTLY DUE TO DIFFERENT CROSSOVER SETUP!
  

6. WHY IS IT SO EXPENSIVE TO REPAIR MY AMP? ITS JUST AN AMP, RIGHT??

• NO ITS NOT JUST OLD SCHOOL AMPLIFIER, THIS AMPLIFIER IS DIGITAL AND HAS 32 BIT DSP PROCESSOR WITH 512KB FLASH MEMORY, SO YOU CAN COMPARE IT TO YOUR SMARTPHONE, RATHER THAN JUST AN AMPLIFIER. THAT'S WHY IT SOUNDS SO NICE WHEN WORKING CORRECTLY. THIS AMP HAS BEEN DESIGNED SPECIFICALLY FOR YOUR CAR SETUP. SIMILAR AFTERMARKET SETUP WILL COST YOU EVEN MORE, WE ARE NOT TALKING JUST ABOUT POWER OUTPUT. THIS AMP IS NOT VERY POWERFUL, BUT VERY EFFICIENT AND EVERY SPEAKER PLAYS LIKE IT SHOULD.

**NOT ALL AMPS ARE FIXABLE, BECAUSE OF WATER DAMAGE. DEPENDING HOW SEVERELY IT WAS DAMAGED. USUALLY SLIGHT WATER DAMAGE IS FIXABLE. PLEASE REPLACE REAR TAIL LIGHT SEALS ON E90/92 AND ALWAYS CLEAN SUNROOF  DRAINAGE LINES OR TOPS ON CONVERTIBLES!!!
