Hi Gang,

I want to put in a pair of subs but I am running into a problem. I drive my 9C1 about 200-300 miles a day for work. With that kind of mileage, I can not afford to remove my spare.
Does anyone have any ideas? I have seen several mentions of free air woofers but I have been told by several audio installers that they are not too impressive and the tubes simply stink.
I am not looking to blow out the back window but just add some thump and depth to my music. If anyone has any ideas or suggestions, I would be greatly appreciative to hear them.
So you have a frame of reference, I am running and Eclipse 55430 head unit with Eclipse 5.25" Point Source and 6x9" Point Source in the stock locations. They are going to be running off of and Eclipse EA 3422 amp.
Thanks for the help everyone. Have a great weekend!

I was the same way didn't want to remove my spare tire because you know the day you take it out you will get a flat. What I have now and I'm very pleased is 2 old school 10" Pioneer speakers in an enclosure or small sealed box. If you just want some bang and aren't looking to remodel the truck go with a small sealed box with 2 10" JL WO or W3. Also depends on what amp will be pushing these subs. That's what I would do if I was looking for baby boom and keeping my spare tire in my car. I'm now in the process of redoing the entire system.

Shorty and Mags,

Thanks for your help with the subs. Do either of you have any pics of your trunk set ups? If so, I would love to see them. Thanks again for the info.

George,

I had an EA3532 (5 Channel) amp driving 5.25 and 6.9 Point Source all running off a CD5441 head unit. The sub channel on that amp could really only support a single Kicker Comp sub. I tried running 2 Kicker Comps but the single channel couldn't handle it. To me a single 10 inch kicker comp was just barely adequate at max volume to integrate into the rest of the system (and even then it was only barely adequate for rock music, and not stuff with more significant bass).

When I tried running the two subs, I had the amp mounted on the back of the seat (spare moved a few inches away from original location). I used two sealed "truck" enclosures for the subs, which were more tall and long as opposed to cube shaped, and could tuck them (with a slight angle) in-between the tail lights and wheel wells. The subs were facing each other. Fairly reasonable amount of trunk space remained without having to get custom enclosures built. These boxes were definately less than 1.0 cu in, probabaly close to .75 cu in each.

If you will be running the EA3422, then a pair of JL 10W0, 10 inch Kicker Comps, or similar subs would be the ticket. I think this would work well for your needs without being too little or too much. I don't think there is enough power there to drive a pair of JL W3's or Comp VRs adequately. One thing to keep in mind about the eclipse amps are that they don't measure their power conservatively. The power tends to be right on what they say it is (as opposed to amps that produce a touch more than what they say). You get excellent quality, clean sound out of Eclipse amps, but you don't get massive amounts of power. So, if you want to run a sub off an Eclipse amp, error towards a more powerful amp (or less power-hungry sub).

In the end I decided to sacrifice more trunk space (but still kept the spare) to run a pair of 12 inch Kicker Comp VRs. I also had to get larger enclosures and a significantly larger Eclipse amp to drive them.

Darkwav,

Thanks so much for the information; it sounds like your idea is just the ticket. I was curious to know if you had any pictures of your trunk set up. I was checking out the picture in your signature but I could not make too much out of it. By the way, what Eclipse amp are you using todrive your Kickers? Again, thanks so much for the help. It is greatly appreciated.

Try this link below to see pics of my current set-up, plus info on the components. These pics have been down for a long time since I put the pics on a different host. However, I finally fixed the URLs on the pics.

https://www.impalassforum.com/cgi-bin...c&f=5&t=000716

Originally, my upgrade plans were just to replace my old amps and subs with the 5 channel and pair of enclosed 10 inch subs I talked about earlier, but since that idea didn't work out as planned after I demo'd the system for a few weeks, I decided on the more substantial upgrade shown in the pics.

The smaller sub enclosures that were used for the 10 inch Kicker Comp's were in a similar position as the 12 inch Kicker Comp VR enclosures, only the subs faced towards each other, and the enlosures didn't intrude as much towards the center of the trunk. I also didn't use the amp rack show in the pick as the amp was mounted behind the spare. I wasn't using capacitors with the 5 channel either.

By the way, what are you powering your 5.25 and 6X9 speakers with? Deck power or an external amp?

Darkwav,

Thanks for the quick reply and for the pictures. That is a very nice looking set up you have there.
As far as my 5.25 and 6x9's, they are currently running off deck power but they will be running off the EA 3422. I have not installed the amp yet. I figure that I will do the installation all at once when I get the subs.
I have to have as much trunk space as I can get for work so I am toying with the idea of mounting the amps on the underside of the trunk lid or up against the back seat.
My local installer has mentioned JL 10's and I have heard lots of good things about them. Were you satisfied with the 10's you initially had installed? I am not looking to compete with the car, I do not really want it to pound. I am more concerned with sound quality than having all the windows in my house rattle.
To compare, what is the volume of the boxes you have now (with the Kicker 12's)? What kind of power is required for the 12's?
Sorry about all the questions but when you are running on a budget, trial an error is a bad thing!
Again, thanks for all the help. Have a great day!
