I am not sure if this was stated, is your system a logic 7? I know I have subs under the seat and I have a logic 7. or would the system even matter? I don't think it would, as long as there are subs under the seat?

Only thing is that the Logic 7 probably has a better amp to start with, so could see less of a gain.

Yep that's exactly my thoughts on it. The picture Andy posted above (location of amp) shows his Logic7 amp, and it is WAY bigger
in size than the one I took out. The standard amp is rather ridiculously small, light, and chincy feeling.

The Logic7 amp looks (in size) about the same as the Thunder 280 I just put in. Of course, just because an amp is big
doesn't necessarily mean it is good, so there might still be a pretty big improvement.

Here is another section that I should've put in my above walk thru. Might be helpful.

*******************************

Old Amp Removal

To get to the old amp (E60), remove the center carpet peice and then remove
the left rear trunk liner. (The battery is below the right rear trunk liner)
You should see the small amp mounted above the wheel well.

First remove the connector harness from the amp. This harness has 2 parts -
and inner and outer part. The outer part will slide to one side, and as it
slides, the housing as a whole will begin to back out of the slot on the amp.
It's a neat connector, and I believe you slide it to the left.

Now remove the amp entirely. It is held in place to its mounting plate by a
slender bar that slides through "hoops" that are on both the amp and the plate.
You should see a black metal tab to the right of the amp that is the end of
this metal tab. Pull the tab out to the right.

Oh and the first couple of songs that knocked my socks off when I got this amp installed:
Billie Jean (Michael Jackson)
Funkytown (Lipps, Inc.)

Try 'em out - they both have made great "demo" tunes when showing off to my friends.

so the amp only powers the subs. If swap the amp maybe something to power, subs, and rear mids would be a good idea?

Check out the recent post about the aftermarket amp called isoamp. I think this would be the way to replace the amp
that drives everything but the subs - but I'm not totally sure about that - sorry.

i think the L7 speakers arent that great, they distort all high volume. look into reus audio, focal and dynaaudio for high end quality.

6spd

not to beat a dead horse, the internals of the amp could also be modified with beefier transformers for more power output.

So the standard 10speaker audiosystem in US 2006 E60 have subwoofers under the front seat? I thought only Logic7 have 2 subwoofers underneath the seat.

By the way how much is the amp? If reasonable I am very tempted to do this too!

westal

Yep the subs are there under the seats. I bet you could get a used amp similar to mine for $40 or so.
