    Placement of the port is only part of the equation when designing a vented enclosure. In fact, it is the least important part.

    First of all, if you plan to put both subs in your car, they should be the same brand/model and installed in the same type/size enclosure. Mix-matching equipment rarely does you any good. In most cases it just causes more cancelation and less bass.

    Second, in order to successfully increase the amount of bass from a subwoofer by porting, you have to design the box based around the TS parameters of the subwoofer. Ported boxes, as a rule of thumb, are larger than sealed boxes so you can't use your existing box. You will have to design a new one from the ground up.

    The first place to look for a design is the manufacturer's instruction manual or website. If they provide a recommended ported enclosure design you should go with that. If they don't, you'll have to use the TS parameters and a box design program to come up with the optimum design for your subwoofer. The size, shape, port diameter, and port length all play an important role.

    If I have confused you in any way...chances are you are not up for the task. Just throw the subs in the trunk and leave it at that.

    i'm a musician so that all actually makes a lot of sense to me. both subs and enclosures r exactly the same. where can i get the "TS parameters"? and where can i get a box enclosure program?

    thanks for the info. i thought it would be as easy as boaring a big hole in the box. shows what i know haha.

    What is the size, make, and model of the subwoofer?

    WinISD is a good box modeling program.

    Sell the 6x9s for something worth using. The only thing more useless then 2 rear speakers are 4. If you must keep one set then sell the others to buy something of the matching brand and series for the front.

    The cheapest amp is never worth buying....ever.
    You should be powering the front speakers with an amplifier long before the rears.

    on the ports, keep the port on the baffle

    Anything from Walmart is not worth spending time or money on. If you are looking to spend money, go to a custom audio shop and tell them how much you want to spend. They will get you pointed in the right direction.

    If your sitting at a concert, do you sit with your back to the stage? Then why have so many speakers behind you? I rarely ever run rear fill in my rides. If you want the best sound, put your money into front components and an amp for them. Bass is easy, good sound is hard. Oh, and WinISD is great.
