OK wire if you like red wire

The following review is for BBSW167, which is a part of the bundle you are viewing.

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

The following review is for MDFS1215, which is a part of the bundle you are viewing.

At the price they are asking,($40 shipped), this is a no-brainer. You'd be very hard pressed to buy the MDF used in this enclosure for the price they are selling the complete box for. Its true 3/4", ( I laid a caliper to it to check), and its advertised dimensions and airspace are spot on.

A winner

The following review is for MDFS1215, which is a part of the bundle you are viewing.

This is just what the woofer doc ordered. The poly fill is already installed. The black carpet looks great. I'm installing a Rockford T-1 dual 4 ohm 12 in the box. I'm anxious to hear how this is gonna sound in my Mark VIII.

Great bass

The following review is for MDFS1215, which is a part of the bundle you are viewing.

Bought this for an old punch 2 I had sitting around that I put into my sons car. Previously it was in a small truck box for an s10. Couldn't believe the difference that this box made. The sub is getting 200 watts from the little fosgate amp that I had for it but it is twice as loud as it was in my truck with no distortion. Obviously I had it in way to small of a box before. I got one happy kid though.

Good box!

The following review is for MDFS1215, which is a part of the bundle you are viewing.

For a pre built box it does the job very well! The poly fill is useless if you need a bigger box just order a bigger box... No leaks what so ever. I did replace it for a custom built ported box.

Great price

The following review is for MDFS1215, which is a part of the bundle you are viewing.

I'm running a rockford fosgate p2 in it. This box has held up great. i can hear a very small leak but only when I was checking for leaks. Otherwise it was inaudible from even a few feet away. Being 100% sealed is very crucial considering it is a sealed box. But overall id say that this is a great box. Cant beat the price. Nothing a little silicon cant fix.

Exactly what I needed.

The following review is for MDFS1215, which is a part of the bundle you are viewing.

I purchased this box to house an Alpine type E sub. I had originally intended on building my own box, but after looking around at the prices of MDF, I found this box, I literally couldn't purchase the materials cheaper than buying this. It's sturdy, and is a perfect match for my sub. I am extremely pleased with my purchase, and would recommend it to anyone looking for a very well built, sealed, enclosure.

Works very well with my Rockford Fosgate sub system in my car.

The following review is for MDFS1215, which is a part of the bundle you are viewing.

Yes its a prefab box, it is constructed very well with .75" MDF. Solid no leaks.Carpet well done.Looks nice. Just match the air space you want for your sub and your done. I could not build this for the price i paid, so its a no brainer for me. If i was looking for ported or vented i would build one myself because of propper tunning. Just wanted something simple and this exceeded my expectations.
