It's not boomy yet - well, I don't know as I haven't installed them. Do you think they will be? I had read stuff about 10"'s sounding tighter, but I thought perhaps since these were HEX's and so renowned for SQ I might be ok. And I'd also heard that bass is the first thing to leave out the open top of the car at speed and that it's a good idea to compensate.... but am I compensating too much?
