Problem when turning off

Hey guys.. I just installed my 12" alpine type-r along with my jbl bp600.1. Everything works fine, except when I turn the car off.. the subwoofer produces a couple of extra beats.. Also I noticed when I turned the car on and tapped the break pedal you could hear the sub beat a little bit. Has this happened to anyone else? Bad ground??

definetly need to make sure that the ground is on bare metal, no paint, and not loose. if that doesnt work, try another spot a few feet away, or on another part of the chasis. also make sure your deck is grounded properly, no poor connections, or ghetto wire nuts or anything....good connections. any improper crimp or corroded conection or wire will induce some noise, or present an easy path for system noise to get in.
another tip with the jbl bp amps....if you didnt know already or havent already done, fill in all 4 rca slots on the amp with y-splitters. you will increase the volume of the sub by a significant amount (30%+).
let us know if this helps!

Yup, definitely had the Y adapters on there.. So you think it's definitely the ground? Thanks for the quick reply
