If you're not too concerned about the space behind your back seat, you can order a custom box from just4effect.com. 8, 10, or 12 inch subs with a single or dual subs. I've got a link in my sig showing the box I got. Works very well with the top on or off.
I currently have the just4effect with a type r. It's a great enclosure but sometimes I'd rather have the space so a proper center enclosure would be the perfect compromise.
I went with a 6" kicker CVT-652 in the oem enclosure. Bought the sub installed and it was okay with the factory amp but then I decided to upgrade and found a kicker dx250.1 and with that it sounds really good.
Ya. I did the same. The kicker is a good sub, however, being a 6.5", it has its limitations. I have a 500 watt Arc Audio pushing it, which is more than enough power. For me, around town it's ok. For freeway or top off, not so much. Friday should be the day that I'll do the install.
I am using the Infinity BassLink, which is a 10" sub with a passive radiator. Fits in the back of my LJ nicely and doesn't take much space. It really puts out a nice, impressive sound. I have a Kicker CVT6.5 wrapped in dynamat in the stock enclosure and it's playing a nice mid-bass role now. I'll be interested to read about your write-up.
Ya. When I first for the Jeep, I tried a 12" sub in the back. The amount of bass I got was not much. Having the sub in the center, without a seat or tailgate in the way of the sound, I think will help immensely. We will see, I guess. I'll keep you all posted on the install and reaults.
I finally got home last night. Worked on the Jeep this morning.
First, I have to say that the install was fairly easy.
The first thing to do is remove your center consol. Take out the 2 torx bolts in the rear (under the rubber cup holder cover), and remove the front 10mm bolt (under the rubber cup holder).
Once you lift that out, remove the old sub box. On my '03, there were 2 screws inside the consol, and 3 screws around the sub, on the outside of the consol. There are also 2 star shaped clips on the front and rear, holding the metal sub box brackets. Remove those, and the whole sub box comes out.
The next step was really the trickiest, but still fairly straight forward. If you have a storage compartment, as I did, it needs to be removed. There are 4 rivets holding such storage compartment in place. Take pliers and hold the rivet on the inside of the consol. Using a drill bit that is bigger than the rivet hole, drill the rivet out. After a couple seconds, each rivet will break and fall out. Do this to all 4, and the storage compartment will come out.
Next take one of the provided screws and find a drill bit that is slightly larger than the screw. You will need to drill out those holes where the rivets were, and you want a little wiggle room as I found out.
These pics show the storage compartment already removed.
Next attach the provided brackets to the new box. I ended up not using the bracket in the front as it was a bit off center, and is really not necessary to secure the box. Do make sure you put the screws in every hole, because if you don't, you'll have an air leak, and your sub will sound like ***.
After that, install your sub. I put in an MTX FPR10-02, 10" shallow mount 2ohm sub. It fits perfectly. The box volume specs for the sub were a little more than the box, so I used a little poly-fill (bought at any fabric store). Poly fill make the sub think the box is larger than it really is.
Make sure to drill a hole or install terminals to the box for hooking up your sub wires. I drilled a small hole, stuck the wires through, then filled the hole with silicone, then covered it with dynamat.
Once the sub is in, it's time to put the box in the consol. Slide the consol over the box and attach the 4 screws. This was a little tricky, as the holes were close, but not perfectly aligned. This is why you want those holes slightly bigger to give a little wiggle room.
Once all the screws are tightened, re-install the consol.
On a side note...yes, you will need an amp, and preferably an aftermarket deck. Also, I would recommend installing some dynamat around the inside of the center consol as well as under the box on the floor.
How does it sound? Well...KICK ***! I am extremely impressed with the sound quality. Awesome deep bass, without compromising interior space.
