Infinity REF467F

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. Available in a range of standard sizes, they’re the perfect upgrade from factory speakers.

GM speaker adapters

The following review is for 72-4500, which is a part of the bundle you are viewing.

Bought them for the speakers in the back of my 86 Pontiac Sunbird convertible. Car is not mentioned in the product description but it fits :) although the plugs for the front speakers are totally different.

Wires for Factory

The following review is for 72-4500, which is a part of the bundle you are viewing.

These Wires worked great for me. I bought them to have in my 1991 S10 bc i still had factory wires behind my seat for my speakers. After i bought them and installed them myself to hook up to my after market speakers they worked like a charm. I'd definitely recommend these to the next buyer. Thank you Sonic Electronix
