Hi-Fi Amp Dead, Logic 7 replacement possible?

FranticM3 · 03-31-2018, 03:45 PM

Late last year the Hi-Fi amp in my '08 E92 got wet and died. I've been looking on eBay for a used replacement but the original HiFi amp from Lear seems expensive and hard to come by. L7 are less expensive and more available..

Question is, would the L7 amp be a plug and play replacement with just some coding of the CCC? Or is it more involved?

Even if it would work, I know there is a difference of 10 speakers vs 13, not sure if that would arise an issue with sound quality?

Any help is greatly appreciated, thanks!

Not necessarily looking to upgrade the audio, just want to get it working again. I don't daily this car, so audiophile SQ isn't really a priority.

Quick search I found this. Cheapest route, but if you want a better sounding upgrade get the xd600/6 amp with techtonic. There is a major difference in sound quality with the oem speakers especially the two 8 in underseat subwoofers.

You can get a replacement amp on ebay for Hi Fi (The wiring is totaly different and the Logic 7 amp uses Fiberoptics for Input which you don't have in Hi Fi wiring plus the harness is totaly different.) but the bimmertech solution would be best or the older solution is a Jl audio xd 600/6 with Technic Harness. https://www.ebay.com/i/162887085622?chn=ps&dispItem=1 https://www.ebay.com/i/232497808392?chn=ps&dispItem=1 BMW stereo types http://www.e90post.com/forums/showthread.php?t=352586 http://www.e90post.com/forums/attach...2&d=1266451970 http://www.e90post.com/forums/attach...2&d=1260829447 http://www.bmwmotorsports.org/pdf/e7...%20Systems.pdf http://www.e90post.com/forums/showthread.php?t=343673 http://www.e90post.com/forums/showthread.php?t=138949 http://www.e90post.com/forums/attach...1&d=1209780605 http://www.e90post.com/forums/attach...1&d=1209780865 http://www.e90post.com/forums/showthread.php?t=641323 http://bmwcoders.com/forum/3-er-8/bm...1-e92-e93-291/ http://technicpnp.com/menuDiagrams/d...e90_92_93.html http://www.musicarnw.com/page-2/ http://www.e90post.com/forums/attach...3&d=1169133185 http://www.e90post.com/forums/attach...4&d=1278871872 HI Fi upgrades http://www.e90post.com/forums/showth...ighlight=level http://www.m3post.com/forums/showthread.php?t=540446 http://www.e90post.com/forums/showth...hlight=technic http://www.e90post.com/forums/showthread.php?t=532585 http://www.e90post.com/forums/showthread.php?t=833581 http://www.m3post.com/forums/showthread.php?t=443043 http://www.e90post.com/forums/showthread.php?t=324214 http://www.e90post.com/forums/showth...hlight=level+3 Last edited by ctuna; 04-01-2018 at 01:03 AM..
