Hey Guys, Need some help installing a Sub

Here's the deal,  I have 2002 Toyota Corolla.  I'm going to install a sub and an amp.  I have a Rockford Fosgate RFR3110 and a JBL BP600.1.  What I need help with is the sub box.  I don't know much about sub boxes.  So here are my questions.

1. Should I build or buy?

2. I assume sealed is what I want?

3. What volume should it be?

4. Does the trunk need to be ported into the cab?

5. Where should the sub be installed? (close to the back seat, facing the back seat??)

Thanks very much if you can help me!!

I got a good "deal" on that sub, and I wanted an amp that wasn't too big.  I don't want to have to buy a new alternator or anything like that.

Thanks for the help!

1. Should I build or buy? IF you not familier with building just buy a box. Also stay away from Q logic, we use to sell them and they are aweful. They leak, and they have cardboared ports and all the effort goes into the looks not the product.

2. I assume sealed is what I want? Sealed is a great all around sounding box, ported will give you more bass and play louder but will not be as accurate when it comes to over all range. You can still get a lot of good bass out of a sealed box.

3. What volume should it be? As close as possible to factory specs. They usually give you a general range of what the sub works best in. When you go out of that range your sub wont die but may not have the same power handling and capabilities that its rated at.

4. Does the trunk need to be ported into the cab?   No. If you throw down the back seat it will play louder but it will still sound fine with the back seat up.

5. Where should the sub be installed? (close to the back seat, facing the back seat??) I would go with it against the back seat firing towards the trunk 99.99% of the time it will always play louder that away.

I HIGHLY recommend you take a look at this PDF file.  It's RF's manual for the HX2 subs and it has a lot of helpful information.

Key thing to note here is that they specify a sealed box volume for the 10" Power HX2 of 0.625 cu. ft.;  unlike the other models though, they do not show any range of possible volumes, they just show that single one as being THE optimal volume; I'm guessing they expect you to build a box that is almost exactly that size--no bigger, no smaller.  You do not need to use the dimensions they give you, just remember the 0.625 cu. ft. part and go to the12volt.com's own enclosure calculator and plug in some numbers to see what gets you closest to 0.625.

Do I have to consider the speakers displacement when calculating the box size?

Ex. Would I take the 0.625 and add the 0.115 to get 0.740??????

I'm going to have someone build me the box this weekend ,so if someone could let me know that would be great.

Thanks much,

Rico
