Infinity REF687F

New Reference speakers are designed to deliver Infinity’s signature sound in more vehicles. They feature edge-driven textile tweeters for smooth, clear highs and the larger models offer an adjustable tweeter output level control for high-frequency optimization based on installation location or the listener’s preference. Oversized Plus One™ woofers offer more surface area for higher bass output and enhanced midrange performance. Plus, our newly engineered baskets are optimized to fit most factory speaker locations.

Easy install

Great product.

The following review is for 72-5512, which is a part of the bundle you are viewing.

Product does just as described. Would not hesitate to purchase this item again. Metra has a very nice product line with lots of hard to find adapters and cables. Better application listing would be helpful.

No Splicing Involved-GREAT!

The following review is for 72-5512, which is a part of the bundle you are viewing.

I found these speaker jumper harnesses, GREAT! I needed to replace the factory speakers in my Ford Ranger, with aftermarket speakers, but I didn't want to cut and splice the factory speaker harness. These sure came in handy!
