Hey Whats up guys.

I thought its my turn to contribute something to this forum.

Last week I finaly got time around to install a 10" JL sub in a rear of the deck. Its very simple and you can run an aftermarket amp as well.
The bass is very clean and punchy without any rattles, low base will shake you nice and sound quality as great. I have a 2 4" jl's on each side of the sub.

Step 1 remove your factory sub from stock location.
Step 2 rip out the speaker cone frome the speaker(you should end up like in this pic)




Step 3 Cut off the 4 structual suport arms from the magnet to the O-ring(Made out of aluminum, becarefull not to damage the plastic mounting tabs (You'll reuse the O-ring part)



Bellow is pic of the subwoofer thats going in.




Step 4 predrill a pilot holes on a top of a suboofer plastic O-ring coordinating with aftermarket subwoofer mounting holes.

Step 5 (Is optional and a longer step)I separated the plastic top ring from the metal portion of a O ring, sanded down both sides and glued them back with epoxy to solidify and seal everything.
The SC400 stock heavy rotor is placed on top for superior adhesion.






Step 6 Place a subwoofer on the O ring, making sure everything is even on each side, and using a short self mounting screws attach the sub to a ring assembly by simply using a screw driver





Step 7 Reinstall the sub assembly back in the original the location, and plug in the harness.



The cover does not fit over an aftermarket sub, I am working on that right now


This is whats pushing it, I removed the stock amp and cd changer to mount my Alpine mrp500


The subwoofer clears gas tank by a 1/2" to 3/4".
I didnt want a box in the trunk because of the weight and space, so this was the only way to go.
I am glad I did it!

I have always liked the way JL looked and sounded. I figured it couldnt fit, due to hitting the gas tank. I would like to see the finished product with the factory cover installed. Looks good.

i did have a 10" memphis sub on the stock location but sold it..all i did was remove the stock one and drop the memphis into the opening, i didn't even screw it down. it never moves around or anything like that and it clears the stock cover..sounded great w/ a cheap amp. had plenty of space left between the gas tank, about 3"-4".

That's a pretty sweet setup and good choice on the amp! I've got the same amp and I love how small it is.

I did almost exactly the same thing to mine in May, except for step 4 - and a cheap 300W amp (bridged), and it sounds very good...nice job & pics

Only thing, my cover fit right back over the JL...weird

looking good, mine cleared the cover but one less thing you have to worry about rattling.

Not a fan of infinate baffle, specially when the sub was not ment to be one. I personally think they are a waste, but it's your car, your money, kudos!

Is that a Free-Air sub?

Im assuming its still considered free-air still. Great write up

better than having two 15in subs weighing somewhere around 150lbs in the back
