It has been over a month since the install. They are just now breaking. I use 2 of them in a sealed (1.5 cubic ft per chamber) box. Matched the subs with JBL GTO 700.1 @ 2ohm. Gain is about 3/4 and bass boost less than half way. My ears hurt. They hit so hard the whole car(02 Accord 4dr) shakes so much. I get the great lows which i really wanted. I would recommend this subs to anyone. I do not have any cons so far. I will update my review in 6 months or so.

Customer Testimonial

I just recently bought a new car stereo from Sonic Electronix. Their customer service was excellent and they got my order to me before the holiday season after purchasing the week before the holiday for FREE! I am definitely going to shop at Sonic Electronix a lot more often!
