Enclosure and door cutting questions

[Drewet88]

Before I didnt feel comfortable with cutting my doors for sound but now I think I'm ready to go for it. I measured my doors and the depth would have to be 2in max before it got in the way of other things. I've never done anything like this before but I'm always up for a learning experience. Any special tools or advice anyone could give me. Or even some instructions or else I'll be winging it.

Enclosure question, I'm also going to try building a custom enclosure. Its not my first time building one but it will be my first time desiging and building the last time I just used some plans I found on google. I'm going to make my first box for my pioneers and if I do a good job I will make one for my kickers (I like to switch them out from time to time.)

I have 2 pioneers TS-W306DVC
Recommend enclosure size is .85-1.75 cubic feet
SPECS ON SUBS:
1000 watts max
400 watts nom
frequence 18-500mhz
sensitivity 89 db
13" by 7"
mountin dept 6 1/4"
*Taken from pioneer website*

I would like to build them in their own seperate enclosure for the way I want to position them. Is there a program I can try using for help or do I also have to use the trial and error method.
O and I would like to go ported my last box was sealed so any porting tips will also be appreciated.

thanks

Should I try using the RE Calculator for my box design?

I've heard good and bad things about it whats every else opinion

EDIT: I've been thinking about adding a second battery in my trunk around the same time I did this install. I can get my local stereo shop to do it but I was thinking how hard could it be? Whats involved with adding a second battey what other materials would I need. I have a Duralast Gold under the hood right now, should I put that in the trunk and get an optima for under the hood?

Like always suggestions/comments appreciated

you can cut mounting rings to lift the speaker out a little from the door hole.

Subs are kinda picky about boxes and VERY picky about ports. If you build a ported box, it will be tuned for just one set of subs. You will need another ported box for the second pair. WinIsd is pretty good for port calculations.

Both batteries need to be as close to the same as possible, if not - one will drain the other. As far as mounting in the trunk, it is essentially the same as wiring the power to another amp. You will need a splitter for the power wire coming the front battery, then a short wire that is grounded to bare metal in the trunk for the - terminal

[Drewet88]

So I could technically go bigge on the door speakers if I'm willing to let them stick out a little bit. Nice. Any advice on cutting the hole?

And if I did the battery should I go with zero gauge all the way through and then just hook it up like an amp. And then use the battery in the trunk for everything instead of the one up front?

[PaulD]

yes, but you may have to modify the door panel if they stick out too far.

you can't do it that way, the two batteries will be in parallel - so both batteries will powering the sytem. You can use an isolator to keep the stereo from draining the starting battery when you play the stereo with the car off.

[Drewet88]

O. Okay I got it so the second battery would only be used when my car was off. Would I need a stronger alt to charge both batteries.

Also do you know of anyone I can pay to design a nice enclosure for me from the forums. I trust you so anyone you recommend will also be trusted.

Thanks

there used to be several guys that would do it ..... most have been banned (not by me) or just moved along.

the second battery will be in parallel ..... so both batteries will be powering the stereo AND starting the car (and being charged when the car is running). With an isolator, the starting battery is isolated from delivering power to the stereo when the car is off.

[Drewet88]

O. Gotcha I'm guessing it would be cheaper to get my 1/0 gauge online instead of from my usual stereo spot since I'll need a lot. I was told about 30 feet.

O and I found Ngsm on ca forums. But theres so many people there offering to build boxes I have no idea who to go too.

[Drewet88]

What website would you recommend for ordering all of this stuff when I asked for about 30ft of 1/0 gauge at my local shop they laughed and tried to sell me anothe cap saying I didnt need a battery in the trunk because I'm basically not pushing a wall of subs.

They also said they dont make speakers that can go in my door without a lot of modification. I have since realized my stereo shop doesn't know anything compared to you guys.

[PaulD]

Caps do NOTHING for loud bass. And tell me why you want a 2nd battery ? how much RMS powere will you be pushing ?

[Drewet88]

The battery will be for future upgrades when summer hits I just like to have everything ready ahead of time. I know caps do nothing for loud bass thats why I didnt talk them into selling me ANOTHER 4 fared to run in parallel with the one I just took. I heard they are another strain on my alt.

In my head I can see big plans for some powerful and clear bass. (More clear than powerful) I know its easy to be loud but its not so easy to be loud and sound good. I just figured I would make sure I have the power to run the setup I have in mind for the car.

Do you think a seperate battery and a H/O alt or a dual stock alt whichever I can afford at the time is overkill?

Edit: I also thought about adding a carputer in the future for movies and such when I'm sitting outside of school waiting for my next class to start.

if you're running under 1krms you should be fine as long as you do the big 3 on a better battery and a stock altenator.

[PaulD]

I think you can get like a 200-300 amp alternator pretty much any vehicle, that should be enough. Caps aren't really much of a load on the Alt, large batteries are (or can be).

[Drewet88]

I have a brand new battery (bought yesterday other one had a dead cell) 800 CCA and 1000 CA. Its also Dual Terminal So I figured I could do something with that. It was one of the strongest batterys I could get at autozone without going to an optima.

My current amp is only 120 amp but I did do the big 3 with zero gauge. I was told there was a way to get two stock alts put on my car all I would need is a special bracket and belt. It would be cheaper than a H/O but I would get close to the same results. I've never heard of it though.

I would like to ad to this thread in hopes that you will remember to safety when your are adding these accessories to your vehicle.

1. You will need a breaker, or at very MINIMUM a fusible link between your two batteries. If you do not have one, you are likely to blow your two batteries up.

2. You will most likely need a MINIMUM of a 200 amp alternator, a 400 would be nice, but might be over kill. They are expensive, but it will save you in the long run from going through stock alternators all the time.

another thing I feel I should say as far as adding batteries, caps, and subs. If you don't know what you are doing, it would be very wise to have a stereo shop install it for you. I know nobody wants to pay someone else to do things like that, but I suggest it for several good reason.

1. If you mess up, or blow up your vehicle, you will have no one to blame but yourself.

2. Stereo installers in shops have to warranty their work, if they mess it up, they have to fix it for free.

3. You could learn from how they install it. After you get it home, you can take note of every everything they put in, then you will know the what you need the next time you decide to install yourself.

As far as the door speakers go, just remember to watch out for your window when it is rolled all the way down or up, if you speakers are to big (deep), they can stop the window from working properly. It sounds like you've checked to make sure it doesn't get in the way of anything though, but I just wanted to make sure that you checked to see the window will have safe room to roll up and down. If they are to deep for the door, you can find what's called 'kick panel spacers'. They will give you a good mount for your speakers and bring them out of the door so they don't get in the way of anything.

As far as an enclosure goes. That is really left up to the imagination. They main point of an enclosure is to protect your speaker from getting kicked or broken. As long as it does its job and fits around the speaker without interferring with the speaker doing its job, you should be fine.

Hope this helped
