The HD stands for "Heavy-Duty". It is a different model and the cab is different and this box does not fit the HD models.

I have a quad cab, but the box has more cutouts then what was needed for my truck. If you have factory under seat storage it might fit. the box is really well built and the bass is tight. Don't expect really deep bass though.

The shallow mount will most likely have a smaller magnet on the back for truck style boxes. A smaller magnet can make less bass regardless it's power handling capabilities. But you can fit it in really small boxes.

I have a 1500 and got the R/T Dual 10-inch Chevy extended cab sealed speaker box and it has been awesome. Push a lot of watts thru 2 kickers and its held up good for a year to this point.

Hello I would Google your dodge speaker size for outer dash, or you can do what I did , I went to a car audio shop and asked for a estimate for my front dash speakers and model choice. Then I said ok thanks I'll come back :). I found the speakers way cheaper on Amazon. Found a video on YouTube on how to install them. Then I saved money that way. Shop estimate $175install. I found them on Amazon for like I think $35 and took me a good half hour to do. Cause of the type on car I have. Well good luck!

I have a full enclosed box and it sounds great. The design to my box was custom, since for this size of sub, it is a must. The thickness of the box is 1 inch. My sub I have installed in my Baja power boat, so for this reason, I had to have my box made with special marine grade compounds to prevent expansion and distortion to the box. But if you plan on having installed in a vehicle, you shouldn't have an issue with that. One suggestion, this sub does require a lot of power, so I would highly recommended at least 750watt HD amp from JL audio.

I am not sure. What is the difference, ten dollars? I absolutely love my unit. Get the hd radio, you won't regret it

The Autotek has knobs SubSub bassMid bass Mid Treble and the blue light is very cool looking and had a built in crossover but if your using the Pac knob u will need two Couplers one for the head unit and one to the amp .....

I used Audio Express for my install. They did an excellent job and have compatibility info on the stereo units. Pretty sure theyre nationwide too. They shd be able to answer your questions. Good luck.

It depends of your entire equipment, but yes, the ZxR sounds better than the HD. I did that upgrade.

Depends on the size of your box... All boxes have different dimensions... Look at the item descriptions and specifications and check the mounting depth is smaller then the height of the box... But i would recommend u get a shallow mount sub... I have a 1000 watt boss shallow mount sub in my pickup and it sounds great!

If you have the space I recommend you get a 3.5 cubic foot box ported. A sealed box is only for small spaces like truck boxes. Ported is always better than sealed, but port must be tuned correctly for the subs, my box is at 36 hz and these sub pound crazy, great for the money! I have a 3000.1d hifonics amp powering these cheap babies.

The HD version is made of aluminum while this one is plastic. This one is also slightly larger. The sound quality on the HD is better also. It can go louder, has more bass, and is also more clear. They are both excellent products for their prices though.

I needed spacers for my kickers to fit now I have to have the seat up while playing music! When the seats are down I'm afraid of hurting the speaker because there is no space in between then bottom of the seat and the speaker! I'm not sure the specs on your speakers but you might need spacers if they aren't low profile speakers! And if I were to buy this box again I would buy the ported one!

Speakers have a double key hole mounting bracket attached. The back of the speakers are particleboard, so if you needed a different receiver for your mounting brackets, you could remove the factory mounts (if they don't work with yours) and install a bracket that would work.

There is a junction under the seat . Unplug the junction and insert the supplied splice and reconnect the junction . The splice has a spot for power to the amp. This for A HD
