| Logic 7 amp replacement from range rover 3 LM |
|
Hi all!
I have D3 2006MY and replaced stock H\K mid-line system with hi-premium logic 7 with full replacement of speakers, some wiring looms and amplifier.
As i read on this forum it's ok to buy amplifier from any source because part numbers are same: XQK500105.
All done, wirings are there, speakers are set, CCF updated for AUD4 and IHU saying logic 7 is ON.
But sound is terrible: subwoofer plays all sounds, not bass, rear doors bass are off.
Errors loading says that calibration of amplifier is not working with audio head unit. and speaker 12 (subwoofer) amplifier is not connecte (that's ok because RR3 have separate amp for sub)
I read some topics here with same symptoms, and found out messages from BBS SPY and Wiggs about re-flasing calibrations of amplifier.
Friendly car repair service for LR tried to help me flash this amp with SDD and failed with message: No software parts are available for your car.
What to do now? How to re-flash amplifier with SDD?
Thanks in advance

Hi,
I can't confirm which FFRR my logic 7 amp came from but after ruining my 2005 Disco 3 one I got a same part number one from ebay for a RR and it works fine.
Is it possible that either the setup is wrong or the amp faulty? Series 1 V8
Series 2 Hibrid V8
Discovery 3 HSE V8

Amplifier working well, confirmed. More of that: my friend bought same amp from rr3 and he came to same problem on his ranfe rover sport. More of that we tried our amplifiers on RRS with factory logic 7. Replaced original amplifier with ours and faced same issue: no bass from rear doors and no subwoofer.

So, we finally did it, saving it there for history
long story short: we dig in logs and find out that SDD reads somewhere value of entertainment system as middle-hi, but override it from user selected value as premium
So, we placed my amp into RRS with factory logic 7 and tried to flash as new ampliier
And it works! SDD agrees for this is applicable amplifier and allowed to flash it with RRS equalizer calibration file.
For now i placed this amp in my D3 and sound became really great! bass from doors, bass from sub working really cool!
So that's recipe how to flash retrofit amplifier.

I am running into the same situation. Installed the Logic 7 amplifier and the CCF has set to AUD4L. I have the Logic 7 option available at the IHU. However, I dont get any bass from the rear door speakers and the tailgate subwoofer is playing full range music.
How can I solve the problem if I dont have a RRS to put the amp for flashing? I tried to run "configure new modules - audio amplifier module" and it failed to complete with the message "unable to determine missing files for this part...".
Any solution?

Sorry, we didn't found the solution for this
we tried to fake up config, we tried to fake up SDD variables
only use of car with factory L7, rrs or d3

I just removed the RRS Logic 7 amp and replaced it with a Discovery 3 Logic 7 amp and all the speakers now sound what they should be - the rear door mid-range speakers are pumping out bass and the tailgate subwoofer is giving out bass only. That's a whole world's difference. My conclusion is the RRS amp is not compatible with Discovery 3 unless you have a RRS to work with the module file before putting into the D3.

i think you might be wrong, RRS (L320) is almost equals to Discovery 3 (l319) in electrical and so on
but range rover L322 was made up from bmw and have a lot of differences from rrs and d3 made by ford
so yes, l322 and l319-l320 amplfiers have same part number, but different firmware.
For example range rover have auxiliary subwoofer amplifier, that's why logic 7 amplifier send full range music to it
