JL XD400/4
Does anyone know if I can send a speaker level signal from my 2010 Base HU directly into a JL XD400? I realize it won't be a flat signal but is there a technical reason I need any other device inbetween?
Thanks |

The manual, page 6: http://mediacdn.jlaudio.com/media/mf...pdf?1346971846
It doesn't have convenient speaker level inputs, but you can probably get away with splicing the speaker level wires onto RCA plugs. Radioshack sells a few different kinds. EDIT: A better question is, why bother? Your stock amp is in the trunk, presumably where you're mounting the new amp, thus giving you access to both line level and speaker level signals. |

He has no stock amp if he has a 2010 base system.

You could get a cleansweep and run it into that then to the amp or try to recode to Hi Fi. |

I was under the impression that the most basic audio system you could get in US E90s was Hifi - was that only true for a subset of E90 years?

For about $65 extra (over a new eBay XD400/4) I would get a Zapco DC200.2 for the a front component set and a RF P300-2 for a pair of woofers. The DC200.2 can correct the signal and keep the gongs OEM-level. It really works in the Stereo system: http://www.e90post.com/forums/showthread.php?t=767449 |

2010's and some early 2011's got the base system
US 2010's and some early 2011's got the base system.
The worldwide base system with no amp . There were a lot of people pretty upset about this. BMW reinstated the Hi Fi as lowest level US system around sept of 2010 in 2011 builds but still a month or two of base system slipped through to 2011 . They are easily identifiable by the lack of tweeters in the front doors. The reinstated Hi Fi and L7 system now does not have tweeters in the rear area's. Also they dropped the pre wiring for a lot of stuff that year like for the alarm system. http://www.e90post.com/forums/showth...Stock+Amp+2010 http://www.e90post.com/forums/attach...2&d=1266451970 Last edited by ctuna; 11-28-2012 at 07:32 PM.. |

In this particular situation, a LOC is a must.

there have been issues with programming the 2010 HU

Most have said it can't be done (at least to the base unit setup)but I thought taibanl was successful at it. |

As stated before, the OEM HU peak outputs exceed the XD400/4 peak input sensitivity. You can try and find out what would happen without a LOC, it is up to you. But the correct way is using a LOC.

I ended up bringing the JL back. I have a DC360.4 that I was having a problem with but it's at Zapco now and I'm just going to wait for it. It's a great amp -- seems crazy to ditch it.
Technic, I would love to know what frequency (and at what Q) you are notching that gong out at if you don't mind sharing. |
