If you want to have something that will set off alarms, wake up your neighbors at night, and get tickets buy 2 of these subs. Wow i am amazed how powerful they are... i have around 1100-1200 rms going to both of these subs but they still want more power. The spoiler of my saab fell off when i was on the highway because the sub was knocking the bolts out of place. If you do buy this product make sure you can power it or eles its useless, and also have cap for it. I just put a rattling kit for my trunk and it helps a lot... it still rattles a little but its much louder and cleaner bass i recommend buying that from this website. I bought two of these subs for 320 dollars on a different website.
