I have for sale a 10" Infinity 550wt RMS, 1100wtMAX sub with box. Sub is loud and bumps for a single 10. Sub is flawless and has alot of life left in it. Used for about 4 months. Its about 1 1/2 years old but just started using 4months ago. Now since i am tight on money i am getting rid of system. I also have a vented box with glass face to go with it if wanted. BEST OFFER TAKES IT.
