Great sound and good value

The following review is for ZS525CX, which is a part of the bundle you are viewing.

These are durable things. They feel well built and put out great sound. Fit in 08 ram was odd, I had to drill holes because the factory speaker use a 3 tab hold down and these are 4. Well worth it though!.

Great little speaker

The following review is for ZS525CX, which is a part of the bundle you are viewing.

I bought two sets for my 2003 Ford Explorer and they fit perfectly. Had to get scosche adapter bracket but they fit like a glove. Yet to see how they sound but with Hifonics you can't go wrong.

The following review is for ZS525CX, which is a part of the bundle you are viewing.
