7 series e65 logic 7 amp

[Steve3361]

My problem was my 7 series logic 7 amp not working at all, expensive to fix or replace, i was considering new head unit or new amp but in the end I removed the back parcel shelf speakers easy job, ran wires from the feeds into the boot, connected them to a high low output line converter with remote turn on, this then fed a lepy amp bought from ebay, the feeds from the speaker out put was ran to the logic 7 block connector to feed rear door speakers, also feeds back to the parcel shelf speakers, separate base output from amp to logic 7 block connector to feed under seat subs, power for amp was from the logic 7 block connector with a relay for the amp switched by the remote turn on, I have also carried out the fm tuner mod to get hifi quality music to the ask unit from my phone or tablet, the result is all speakers now working crystal clear hifi quality sound, with good bass. All controls work as they should ,bass, treble and fader, all work is within the boot apart from parcel shelf speakers, so no other disturbance to the interior. https://www.youtube.com/watch?v=CVqXmjucgm4&t=60s, the fm tuner mod is https://www.youtube.com/watch?v=8sXUc3feP9A&t=39s
