Since the end of school is near, my school had its annual "Spree-esta" today. All it basically is is a field day that happens to include a car show. Although I didn't get to take a close look, several of the trucks had sound systems that "boomed" and vibrated the windows on the school.

After being in the excitement of it all, I began to think that it might be kind of cool to have a system like that for events such as Spree-esta or Slammin' 'n Jammin' (another car event in town).

I sort of had a design concept in mind to place a maybe 10" or 12" woofer in between the two seats and above the console in the wall (Viper style). Good idea? Bad idea? What's behind there? I also wouldn't be opposed to having one put in with the forum's famous "custom sub box" that fits into the left side of the trunk.

A few questions:

Would either position cause rattling of car components such as the rear hatch or hatch glass? Also, will just one woofer give you the bump that you hear from other modified car stereos?

I wouldn't want the woofer to stay on constantly because it can sometimes get annoying, so is there any type of "kill" or "Independence" switch that could be installed (possibly on the SRT's dead switch) that could be flipped and have the additional amp and woofer kick in?

Any suggestions or comments mean a lot. While I have planned a home theater system, I have never tackled a car setup, so I'm an ameteur. Thanks for any help!

 

A good sub will make the license plate dance.

 

A sub anywhere in the car other than the trunk is not doable. Well, anything is doable for the right amount of money, but it won't look or sound as good.

The custom pre-made box that many members have with 1 twelve sounds awesome (and would be enough bass for me), but if you want to "rattle windows" you'll need two subs.

 

Behind the wall is the gas tank. Killing the amp is easy with a switch on the remote turn on lead (think 12v switched output off the receiver in your home theater or power center that triggers stuff like a projection screen ect.). Depth of the box and woofer will be tough, although there are some challow woofers from pioneer and kenwood that are around 3" or less...my expereince in cars with them had not been good...think Lotus but if that is the only solution then go for it. You might want to consider an infinity basslink if you are trying to keep it small but want some extra oomph.

 

Yeah. If I ever were to do this, my main goal would be to save space and make it look as stock as possible. I found out that the person who had the system up at school today had 2 Kicker 12"s. I was looking on the circuit city website at some and was wondering about MTX's new smaller JackHammers. They look nice!

As far as an amp, for the people who have gotten the custom sub enclosure, where is the bst place for the amp? What size amp do you get?

 

If you are looking for a small speaker with alot of sound I would go with the Kicker solobaric 8"L7, (square Sub) They are pretty easy to build custom fiberglass enclosures for and they have a low amount of space required for them. Plus they move about the same amount as a 10" round sub.

 

So I know that there have been several posts with subwoofer placement proposals, but has anyone ventured into seeing what was around the first aid kit hole. Could it be widened any to accomodate a sub?

 

Just stryrofoam... pull out the foam and check the shape... you can cut from there.

Cheers!

 

So do you know if anyone has tried a subwoofer here? From what you say, it seems like it wouldn't be a problem.

 

Should not be an issue and I think one person did make a sub to fit in the space, but I can't remember where or the thread name.

If you just made a box to fit the same size as the styrofoam that's in there, you could easily make one. I believe there is more than enough room for a 10 or 12 shallow throw sub.

Good luck!

 

I tried pulling up the styrofoam and only the top lefthand corner would budge. Nothing else.

 

Alright. So, I've sat down and thought about it and I have concluded that my main goal for the stereo in this car is to replace my non-nav unit with a OEM nav system and to add a subwoofer...

I really like the idea of being able to fit a box in the empty first-aid slot, but am clueless as to where to even begin with a box, etc. I have been looking at the woofers and the new 10" or 12" MTX Jackhammer looks pretty nice (http://www.circuitcity.com/ssm/MTX-J...oductDetail.do). But then I also wonder if I should go with a higher-end sub such as the JL w7 series. I don't mind paying the extra, but wonder if there is that much of a difference. As far as an amp (which I would place behind the passenger seat) the Pioneer 800W mono looks good (http://www.circuitcity.com/ssm/Pione...oductDetail.do). I'm assuming a mono amp will be alright because it will just be pushing a sub. I know this may be hard to believe, but I know nothing about car audio, so give me some input!

For those of you who have added a sub but kept the stock system, how do the speakers stand up to a sub? Does it drown them out too bad? Wrapping up, if somone could possibly look into the first-aid kit hole subwoofer placement, that would be wonderful!

Thanks so much for the help, everyone!

 

Ugh, here I go again.

Since school has started back, it's put me back into the mood to start modifying my stereo. I am NOW thinking about a slim-line subwoofer from either Pioneer or JL. I'm all of 5'8" so the room behind the seat wouldn't be an issue. I know that cars such as the 350z have a sub behind the driver seat, but is this irritating?

Also, I am not sure if I just need one or I should opt for 2 subwoofers for the bump that I want. Has anyone tried the slim woofers in our cars yet?

 

well keep in mind like someone said earlier directly behind the seat is the gas tank. and that ive been told that is some kind of boron steel. so it is supposedly really hard to cut through. i know that there is "some" room in that wall for speakers and the only reason i know that is because A. there are already speakers there and B. the roadster roll cage gets bolted in there. but its not to far down from the top of the back wall. i've thought about putting a sub in the first aid kit area as well. and i do know in order to get rid of vibration you need a HECK of a lot of dynomat.

 

I wasn't thinking about going into the wall. I mentioned that I was short and had to have the seat up to clarify that I think there would be enough room for a small box. I was thinking of a box similar to this that fit behind the seat. 2 seperate boxes if I decided to go with 2 subs. From what I've read, these Pioneer subs hit pretty hard.

Rockford Fosgate has a Crossfire Roadster demo vehicle with a ten in mounted between the seats over the center console area. It looks sick! Check out their website or search the web and see if you can find it.

 

ive never even heard of the rockford fosgate car. i know there there is an alpine car, and a kicker car. but no rockford car. i checked there website and it wasnt there i also looked for photos but never found any

 

Yea, Rockford built one and CDT Audio built one too. I have photos of the CDT Crossfire with a couple different set ups in the hatch somewhere, I will try to find them and post them up. Also, a Crossfire was in the February 2007 issue of Car Audio and Electronics. It was running two JL 10W6v2 subs and MB Quart Amps and components. It look great!

 

Here is the CDT Audio Demo Car. The first set up had 1 12", then they changed to two 10s. I will try to find photos of the Rockford Car too.

 

After seeing these I feel a lot better about the measly 15" x 15" space I used up with my sub. These claim the whole rear cargo space! Not sure they even look that good.
