* Trevor's 2010 Audi A4 Trunk Build. Sundown. Fi.*

[helotr3vor 10+ year member]

Just got a new car so its time for the new build. I now have a 2010 Audi A4 Premium and craving to put a sub in the trunk. First off, here is the car..

I plan on getting a Fi Q 12d2 with cooling and spider. Its going to have a ported box tuned to 32-33hz with a matching black/silver theme built by DonH. The box dimensions are 35x16x12in with the baffle on 35x16.

The sub will be wired parallel to a Sundown SAX-1200D. I plan on getting a refurbished one from db-r. Im going to be able to hide the amps in the sides of the trunk behind the panels. If I can hide all wires this can be a very clean semi stealth build.

As for electrical, I have 10ft of Stinger Hyperflex and but I'm still unsure if I'm going to do the Big 3. Ive heard some people say the stock electrical will handle 1200w without a problem but then again its always nice to have that extra voltage. Im going to have a Line In Converter to reroute the sundown amp to the stock amp then to the head unit. Now I know this isn't ideal but I've been told this is the best way to route the wires with keeping the stock head unit in this car. I'm open to suggestions on the best Line In Converter for my circumstance. Im going to have knu 4gauge power wire for the amp and knu speaker/rca wire.

I got the itch to get something done over the weekend and got the back cabin sound deadened. I had a few sheets of Damplifier Pro laying around and figured I'd put it to use. I still have 2 full sheets that I plan on putting on the trunk lid once I figure out how to get the panel off.

If you have any questions feel free to ask. Excited to get going with this new build log //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

post a pic of the trunk lid panel. if its the same as the A8, I just helped a buddy do his over the weekend. If its the same, I think it was just a dozen or so little pop tabs around the perimeter and a few in the middle for support.

I would say your safest bet is to ask on an audi specific forum, but at least on the A8 (probably 07-08ish), it looked similar and popped off with some panel tools. that piece looks pretty pricey to break trying to pop it off if theres anything else holding it on that I dont know about.

The dealership might even be willing to tell you?

I got a DIY on the Audi forums im set. I might go ahead and do it in a little who knows.

Yea it was a fairly quick job. Before you do it, do you have the automatic opening trunk or just the normal pop it and open it like a normal person trunk? I know theres an option for one that will fully open and close on its own. the dampening will add some weight, so if you have the auto-opening trunk, id be careful not to over do it on dampening weight.

Yeah I only have 2 sheets left so it wont add much weight at all. I have an opener but I dont think it closes on its own.

 

[chawski 10+ year member]

sounds like you just have the popper with gas struts to open it like any other trunk. The gear driven ones are super pricey so just wanted to make sure before you add any weight to it

 

[helotr3vor 10+ year member]

Yeah its just a popper. Took my about an hour to deaden it and I still got a 1sqft of damplifier to save for a spot I notice after everything is installed.

 

[helotr3vor 10+ year member]

Not much of an update, just used the last sheet of damplifier pro I had laying around. Cut it into 3 sheets and put them in the spare tire well.

First order came in today! Got some wire from Knu and should be receiving my LC2i later today.

1/0gauge Knu Fleks

12gauge Karma SS

RCA Karma SS

1/0 Knu in-line fuse holder

Dont worry about the length my battery is in the trunk already //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Going to be mounting the factory amp behind its original mount. And somehow mount the new amp where the factory amp used to be. Might be a little tricky but I should be able to find a way to make it work. If I cant, I can always mount the factory amp above the wheel well.

Thats it for now. Maybe I will route some wire tomorrow.

Got my information wrong they split my order cause they had to get the LC2i from somewhere else. They shipped my 18ga wire that im using for power and remote on the LC2i. Along with 2 1/0 to 4ga input adapters that I hope will fit.

Thanks Joseph, welcome! Should have everything completed 2 weeks from today if everything goes smooth.
