The following review is for Reference 3004A, which is a part of the bundle you are viewing.

Got this as an 'open box' looks bran new to me! Still factory sealed at that.

Great value for the price on sale and great little amp by a brand you trust JBL/Infinity..

Quality amp!!!

The following review is for Reference 3004A, which is a part of the bundle you are viewing.

Very nice overall quality and design! Easy to set up and has more than enough power for a typical vehicle set up. I went with the Open Box deal and it does not look like it was ever opened in the first place! I would not hesitate to purchase again!

Looks great from the box. Two day delivery. Am waiting on a set of speakers to be exchanged and delivered to complete the set up.
