i have the amp triggered by an ignition controlled 12v circuit. even when the music starts as i start the car i've never had this happen. what amp are you using? how efficient is your driver?

I was thinking about doing a freeair setup as well, but am concerned with being able to put BACK the stock sub once Im ready to sell the car. Since you cut that plastic, Can the original sub be put back? Im not so sure.

I have a JLA 500/1 monoblock sub amp with a JLA 10W7. It's wired directly to the battery. I have not put the "1000 watt" cap that I bought on yet. I had the battery checked and it's fine.
I think the 10W7, JLA's best, eats power too.

I've never had to use a cap before but according to the local shop MBs are very sensitive to voltage changes. Should fix the problem.

The cap is supposed to go as close to the amp as possible but I wanted it out of the trunk below the mat.
As you can see I have dealt with big connectors for these momoo wires previously and decided to do it the easy way. I perforated the plastic of the cable with an awl then stretched it open with a needle nose, then screwed the post through the cable itself. It won't pull apart like standard connectors will and it was way easier IMO.
The bare posts are not covered for illustrative purposes. I taped then up after taking this pic. Obviously if you have a cap of this size and leave them untaped you might short something out, like YOU. I learned this the hard way with a .25 F cap on my Vette. This is a 1 Farad cap and could shock the chit out of you.
Sorry for the lighting and quality of some the pics.

Cap came with plastic mounting points and you could attach with one set if you wanted to but I just have it wedged between the car and the spare. It's really tight in that area and motion is not possible. I really don't like drilling or altering my E55 any more than is necessary.
If I was to do it again I probably would use a cap designed for 500 watts, it's half the size and could be tucked in a little better. My local shop just didn't have one that small and gave it to me for the cost of the smaller cap. Still it was redicuously over priced.
There is a nice feature on the side tho, has a voltage read out so you can monitor the health of your battery. You could get a smaller capacitor from an electronics store for way less than one from "Rockford Fosgate"

The only time that the accessories shut off is when the stereo is playign loud and the sub is kickin a$$.
One the MB techs explained that if voltage in battery circuit drops below a certain level, even for a millisecond, that's enough to trigger the protective function.
I guess we'll see if the cap cures the problem. I'll let you all know.

So what did you use for input to your JL amp? Did you simply tap what was going to the stock sub originally? (That's how I have my sub box wired... tapping two wires to one of the sub plugs, into a line-out converter, RCAs from LOC to amp.
Not very pleased with the set up and I'm definitely considering doing something like yours. However, my sub is a Kicker L7 1500w and would be quite a bit too loud if I don't get this set up correctly...

That's a very nice setup. I too was looking for more thumps from my factory sound system. This is a great idea without loosing your trunk space. Do you mind sharing the cost of this modification?

I did something similar to AMGfan, not nearly as nice and only a single 10. I ripped out the stock sub, cut out the sheet metal where the stock sub fires down through. Built a box that fires up through the stock location that's only 4.5" thick so I have almost all of the usefulness I had with the stock sub. I haven't covered the box yet, but I'll be building another box for the Boston G5 I'll be replacing my Type R with soon. I'll try to remember to take some pics to show what I'm talking about.

It's not all that bad. Remove the rear seat, headrest (there's a lever that has to be pushed). Some push pins hold the rear deck on, pull those twist the sub, unhook the wires and she's out.
