Box positions in a car

Okay, I have a 99 olds alero and to save on trunk space I was going to make 2 boxes that are 2cubes tuned to the same frequency, but would be different shapes in order to take up less room. The seats fold down so I was going to face one box with sub and port facing into the cabin of the car and have the second box's sub and port facing the opposite way into the trunk.

Would this work well or would it cause problems?

I can draw up a rough sketch if you need more elination to what i want to do.

Thanks
Kevin

Why would you build two boxes, you could just build one and turn it around to see which way works best.

I want to make it fit without taking up any more room than it has to. I dont really have the programs to help me design 1 box that has a different shape than just a cube.

On another note:

Having the port facing the opposite way as the subs... Does that work?

how far should the subs back ends be from any walls in the box? just far enough that they dont touch the wall? or I have heard 3" away from the wall behind them.

In an Alero, the subs are loudest with the box and sub firing into the cabin. The biggest box you will fit in the trunk is externally: 16.5" tall, 39" wide, and 19.75" long.

firing into the cabin with both seats down?... Should I seal off the trunk around the box?

"firing into the cabin with both seats down?"
You do not have to have the seats down for jut daily driving. It does not really hurt the quality of sound, but it does get a tid bit louder with the seats down.

"Should I seal off the trunk around the box?"
If you can, yes. But it is extremely hard in our trunk because it is so small.

The Aleros comes with a 105amp alt stock and just a small battery mount up front. I run 2.5k rms+ on the stock alt with the big 3 and a spare battery in the back. That should be able to handle that hifonics with no problem since it does 1800~ or so.

Glad to see another Alero owner on the forum :-)

What ssubs are you running? I would recommend upgrading your charging system to keep your voltage as high as possible... That amp does draw a lot of power. even though it doesn't give you the full 2000 watt rms...

I love mine. It's not the fastest car but its quick enough +It looks good. I love that the interior has very few rattles and nice stock speakers. I also got a real nice stock paint job on mine... almost pearlescent.

Mark, I will be running 2 Alpine type-r's

Actually I would rather not upgrade any electrical. I was asking nick a question. Should I get an amp with less power since I dont wanna upgrade electrical?

Kevin, I meant that stock alt, big 3, and extra battery would be able to hold it. The big 3 is not hard to do at all on the Alero.

Im not really sure what the big three is... Could you explain it? I'm almost positive that I dont want to do any upgrading on the electrical... How much wattage could run without upgrading?

also nick, I think you gave me your AIM sn but I dont remember what it is, could you give me that again?

Do the Big 3 if you can.

The Big 3 entails upgrading your stock ground straps plus the positive lead from the alternator. These are the alternator to chassis, battery to chassis, and the alternator positive to battery positive.

A bunch of 1 or 0 gauge, 6 ring terminals, a bunch of solder and an iron or torch, and some heatshrink. I don't like the idea of crimping wire to go under the hood. It could cause some damage real if it came loose and the connections will be subjected to much more vibration.

Thanks cam,

Lets say that I only do a Big 3 upgrade. What is the maximum amount of power that my amp should have?

Just try it and see. If your voltage starts getting really low then you need to adjust the gains to accommodate.

So you think I could still go with the Hifonics Bxi 2006?

Kevin, go with that amp and adjust the amp according to your voltage drops. My AIM is: halo scripter

"I don't like the idea of crimping wire to go under the hood. It could cause some damage real if it came loose and the connections will be subjected to much more vibration."

Lol cam, it would only become loose if it was not done right. What I do is buy the closed end ring terminals and crimp them in using a ball-pin hammer. It's a completely safe connection :D

Get a better amp, hifonics is what you buy when you really can't afford something good

And Nick you're giving that amp too much credit.......... ~1600w is the most that amp will do

Haha. So you don't crimp your connections, just solder? I gaurentee my crimped terminals are more secure than that.

Every time I crimp a terminal I try as hard as I can to pull it off.

Lol, I've heard mixed reviews on the output of that amp. I know it is not 2k though.

Same here man.

I dont really need an amp that can do the full 2000w. Also dont wanna spend a whole lot of money so I think that the Bxi2006 will work fine, thanks for the suggestion anyway.
