Logic 7 amplifier possibly blown? Need Help

Hello All,

I have an 06 e90 325i with Logic 7 / Professional / Nav and I think I may have blown the stock amp. I also have a Blaupunkt tha1250 php which is spliced into the logic 7 to feed the 2 under seat subs.

-I have "audio" coming through the speakers but it is very muted and flat.
-All fuses have been checked (that I know of)
-Aftermarket amp has Power

I was wondering if anyone either has a spare L7 Amp lying around or if anyone would be willing to do some testing to see if it is in fact the faculty amp. I'm thinking since the stock amp has a PlugnPlay wiring harness we can just quickly swap them out.

Any thoughts?

Thanks!

Is there an MS8 retrofit? What does it entail? I've been out of the scene for a bit :/

You have to recode to Hi Fi

No matter what you do to do something nice is going to cost
you some bucks.
Most are not happy with the MS-8 alone
You have to recode to Hi Fi
buy a Technic Harness
and you will probably want and amp and some upgraded speakers
for at least the front doors and floors.
Read the MS-8 thread before you consider this.
The other way to go is get a mobridge da-2 preamp the only thing
that will interface with the optical connection from the L7 head unit and
add amps and or processors plus some speakers.
The best one stop canned solutions come from MusicarNW.
Vist there website for a description also there are many example
threads of there systems on this forum.

Meanwhile read this
