well i had these in my Jetta Wolfsburg. they were 50 bucks each so i thought it would be a good deal, but I highly regretted it. They do not bump or pound. It is a noticeable bass increase that you really cant hear from outside the car unless its quiet. They are not very loud and sure wont rattle the car fi thats what your hoping for. all in all it is good for adding clean bass to your system, but they are not hard hitting subs by any mean
