Looks very nice can you please post some more pictures of this project and maybe a video

yep i will im just beginning so next week i should have install pic's i will do video once the LED are in

Amazing. I love it. Please give us as much details as u can. I love the look. Whats on the back of it? Does ur car have L7 or its HI-FI?
P.S. cleaning my foggy lights tmrw inside and outside

Right now behind it is trunk air :P we punched out the metal which was precut by factory just used a mallet to knock it out. Then cut the carpet behind , basically not going to crazy but it will sorta look like the JL audio custom fit box look where from trunk you wont see speakers you see a wall and you will see the amp and a LED lit logo(still not sure what) custom fit so i will have 1 foot still for storage... also blue LED's that will be seen through the two ports and hopefully if it works out like i think it will it will give the cabin a nice low blue glow so im hoping

Not a big fan of blue LEDs reminds me cheap stereo in the civic. I would go with red LEDs not too bright to mach interior color LEDs in the doors rear pillars and overhead. But its just my opinion. Do u have logic 7?

No L7 i got the HiFi system i do have an amp but not the L7 one its about half the size its loud and clear i cant turn it up all the way with out hurting my ears , that not with my subs on. I got the adapter from technics that was for L7 but it works on the HiFi amp aswell which i was a test subject :P glad it worked! and actually me the guy doing the custom panels i will use for leds we already thought red cause one of the panels will be the rockford fosgate logo :P it will look nice i hope

wow....can u run two more subs and stock subs at the same time?

He doesnt have stock sub its not l7

no stock subs the amp that is stock is for the factory speakers which is nice with the aftermarket subs its sounds good the bass doesn't over power it.

cool, post up some more pics if you can, as far as I know even the hifi has subs under the seats. They just suk..

So your stock amp is strong enough to push your pair of P3's?

no got a hifonics amp for the subs

1x Hifonics 1200.1D @1ohm

Any update on this project? Getting ready to do something somewhat similar

no i decided to make it a winter project i got some other things going for my career right now that leaves no time. basically till winter i just got a box, amp and cap mounted in the trunk i did dynamat the inside of the trunk and sprayed underneath for now. wish i could post more i wanted to but im swamped!

If you guys are interested in an amp install, it's fairly easy. I would recommend an amp that has a "auto turn on/off" feature that is triggered by audio source like newer JL Amps just because it is very hard to find a remote signal wire in the 7 series. All you would need to do is run a power source from the battery, located under the jack, to the amp. Run a ground wire to a metal bolt from anywhere in the trunk to the amp. Use a "line out" converter and splice into the L7 amp harness where the subs output is and use that as the audio source input for the amp. Mount the amp securely in the trunk. Get a set of subwoofers and run it to the amp. I'm sure jkidem is more complex and cleaner install. But that's the basics.

Instead of splicing wires all you need is this bro, http://www.bimmerfest.com/forums/sho...4&postcount=51 it's a harness made by a member named Technic that plugs into the L7 harness and gives you audio inputs for your amp and also a remote wire, you can even power the floor OEM subs with an aftermarket amp using that harness

Wish I knew about this harness when I did mine. Should make the install even easier.
