We repair these amplifiers with 12m warranty! Basically if your amp looks like the one on the pictures, we can fix it. These amps you’ll find in these Bmw models:
X5, x6, z4, m3, f01, f02, e92, e64, e63 and may be others. Part number is not very important, because we repair them all as long as they look similar to the pictures here.
This is a newer generation Logic 7 amplifier, found on newer BMW vehicles, listed above. It works very similar way (in basic of course) the way it was working in previous generation amplifiers:
Head unit or CIC sends digital sound data over fibre optic network called MOST, then amplifier receives it, runs through DSP and finally converts to analogue signal and powers up 9 channels in your car and you can hear high end quality sound without any noise or very low noise compared to standard analogue amps.
This amplifier compared to previous LOGIC 7 generation has lots of advantages:
• Class D
• More power output 600W
• Better quality built by LEAR
• Newer more reliable chips used
• Sound quality is much higher
• Less power consumption
• Less heat produced
• Next generation components
• More complicated (that’s why you won’t find many who can fix them right)
Standard symptoms:
-no sound at all
-crackling speakers or sub woofers
-no communication
-other audio issues
After repair you don’t need any coding, it will be plug and play.
Q&A:
1. How does it work?
-Simple. You remove your amplifier and send it to us (it fits really well into USPS flat rate priority box for $12). It takes 1-2 days plus 2-3 days shipping. Please also write down transaction ID from PayPal or ebay on the amplifier so we know all details and where to send it back. If you didn’t make the payment and want to pay once fixed, please provide your contact info (email or phone number):

2. How do I know if my amp is bad?
-Based on symptoms and diagnostics. Usually no sound means amp failed or if speakers don’t sound right.  If we get your amp and it appears it’s in good shape we only charge $50 diagnostic fee.
3. Do you test them?
-Yes we stress test all the amps prior to sending them back.
4.Will it last?
-Yes it should last similar to brand new amps because we install original OEM parts. Check our reviews. We have repaired 1800+ amps since 2011.
Also we install more powerful power chips so it can sustain higher current ratings.
5. I have different symptoms. Can I all?
-If you didn’t find answers here please call us at the number below or email us via ebay.

6. How does the warranty work??
-Simple. If something happens to the amp but there is no physical damage or water damage, you can send it back. All we need to know is eBay or PayPal transaction id. This is how we know all the info: when warranty starts, model of the amp and serial number and what has been done to it.
7. Is it safe for my car?
-Absolutely. We install oem parts, so there is no difference made to the amp internals.
8. Is it legitimate business?
-Yes it is, we’ve been around since 2009 fixing amps. You are fully protected by PayPal and eBay policy. Which means you can always get your money back if something didn’t work out. So far we repaired 1900+ amps, we work with dealers all over the world but mostly within USA. We were the first who designed  in 2010 BMW e65 amplifier repair, so everyone else just copies our design. You can ask other shops if they repair digital boards and most likely you will get an answer “NO”, because they know only simple standard issues with these amps, but we know and can repair digital boards. We are Electronic Engineering professionals and know what we are doing.
9. Why does it cost so much to repair it?
-Well, this amp is fully digital and has nothing to do with old school amps you can buy new for 100$. Parts are expensive and we use expensive equipment to work on them.  Plus we provide 1 year warranty which costs us a lot as well. That’s why you can find only a few companies working on these amps.
10. Why would I pay 350$ if I can find used amp for 300-400$??
– Well, for a few good reasons:
A) We install new oem parts which usually go bad on these amps with years, so it should last longer than used amp more likely it’ll last like brand new one.
B
) This amplifier has your car VIN number coded. So you will not need any coding, because you will get your amplifier back which was coded to your car from factory. Coding is not that simple so buying used amp will not be plug and play. Bmw dealer will not program used amp or any other used part to your car. Only new parts will be installed and coded at the dealer which means it might cost you up to 2000$ to install a new amp correctly. In our case you DON’T NEED TO SEE ANYBODY else which means you will spend only 350$ period. If you buy used one, it will have different VIN number stored and dealer will not be able to program it (did you know dealer only programs new parts????)
C) Used amplifier might work, but its not going to have any warranty, and having new parts and real warranty matters.
