[QUOTE="Utopia, post: 313917, member: 550155"] I'm completely new to this board and I hope this post is appropriate and in the correct forum- if it is not, I apologize. I have a sort of general car audio engineering quandry. I'm currently running a single JL 12W3V2 in a sealed box in the trunk of a 2003 Subaru Impreza. I'm not a DIY type of guy. This is the sub configuration that my installer matched to the Focal 165Ws that I have in the front doors. I have a PG Tantrum 600.4 and 2 of its channels are bridged to drive the sub. (300W RMS) Long story short - I've been through 2 installers and I'm possibly going to be looking for a third. I'm starting to think that none of these installers have a clue. I'm not happy with the bass......its very tight and "hits" pretty well, but the sub is just firing into the trunk. The sub fires rearward. At louder volumes, it sounds to me like the box is just vibrating the snot out of my car. I don't feel any air being pushed around - obviously becuase there is no way for air to get into the cabin of the vehicle. I have done a good bit of reading about sealed vs ported vs bandpass and what I want is to have the sub "hit", but also to have booming bass and to feel air being pushed around. I'm willing to upgrade the sub and even have the box redone if necessary. I also want to add a second set of components (Focal 165W3) as I really enjoy saturated midrange/midbass, but will certainly need more bass to match another set of components. Is it possible to have a "port" cut into the rear deck of my car so that the box and the trunk together form a sort of bandpass enclosure - so that air can then be pushed into the cabin rather than to have all of this vibration? Is this even advisable? If this works, I could potentally keep the box I have and just upgrade the sub to a W6V2 and get a second amp....or could I? I'm thinking the best thing to do is to upgrade to a 12W6V2 because it can use a small enclosure (I'd like some trunk space) and have the box redone so its a bandpass enclosure (both boom and punch), have it ported into the cabin through the rear deck and just get a second amp to drive only the sub.....that also leaves two extra channels on my 600.4 for the other components. How does this sound to you guys? My budget for all of this (new sub/box/amp/components) is not to exceed $3k. Any comments or suggestions would be greatly appreciated. Thanks [/QUOTE]
