Step 1 : Put in trunk


2 JL Audio 10" Subwoofers in a sealed box, With an Eclips 3620 amplifier.

Step 2; wait for order from crutch field to show up



the amp wiring kit will be here tomorrow

:)


I was also bored today so I rewired the sound system in the car from 2 channel to 4. Very easy all you need is

1) wire cutters
2)barrel type connectors for 18 guage wires
3) wiring diagram of the head unit and car
4) 9v battery to figure out which speaker wire goes where.


the wiring diagram is actually, useless.. What is really required is the knack.

Let me know how it sounds. I have been wanting to add some subs to the 240 but people have told me that it wouldn't sound good do to trunk wall and gas tank. I was told you would need to run ports through the rear hat rack/ deck. But I really want to do it.

Looks good, how does it sound? Was wonder about the amount of vibration you are getting from the trunk and rear deck. I was playing with the idea of dynomating my trunk and rear deck and putting some subs in the back, but the trunk lid has so much flex I didnt want to do all that work and have to take it out because of poor sound quality. I am interested to know how your project turned out and what does it sound like from the outside?

Get a T-model (wagon)! You'll get better sound from the bigger interior space.. :-D
A good amp and the speakers from your living-room and you are ready to go..
In the sedan you need more "power" to get the same sound :)

I just searched on another forum about bypassing the fader.

Really all I did was cut the plug, trace the wires and cut what was not needed. After that I was left with 8 wires. Which is where the 9volt battery comes into play.Use that to make the speakers click on to sort through the wires.

My package is out for delivery so I probably wont see it until this afternoon :)


The fuel tank should not post an issue nor anything since these subs are pretty powerful for their size

Crutchfield is horribly overpriced.

I always get my wire by the foot at the local audio shops. Cant go wrong with sealed. You might want to throw some polyfil in the speaker. Get some dynomat for the trunk lid and walls.

polyfill in the sub box? I have a big box of the stuff. I'll look into the dynamat. I really need to get the license plate bolted down since that is a major rattle when the subs really hit

Yes, poly fill will effectively increase the size of the box. Fill it loosely about 50% or so. I have found double sided mounting tape a great help with tags.

So how does it sound at highway speed, on chip-sealed pavement?

Also how does it sound with a window our two open, driving down the highway?

I like to feel the rock n roll beat.

with the windows open at highway speeds I can still hear and feel the bass. With the windows closed its really heavy inside. Outside the car its somewhat muffled.. A lot more muffled than I had expected.

interesting, I will have to try it.Have you done this yourself?

double sided tape for what tags? or do you mean vibrations?

Did you adjust the amp yet? When I had it in my Acura, you could feel the bass hit standing next to the car. I guess the body of a 300d is a bit thicker.:D

There's a boost switch on the amp ... and I think the last time I had it hooked up, I turned the gain way down.

If you use dynomat as spacers between your plate and any place it contacts metal it will cut out close to all of your vibration, it is great stuff.

These are the settings ... the "gain" is turned back and the "bass boost" is off ... you could still go lower on the "low pass" too.

Also, IMO, I wouldn't add any poly fill to that box. Trust JL Audio ... they designed that cabinet for those subs specifically.:cool:

I played with it and it goes lower now.. sweet.

I need to sort out the rattles now. Kinda hard to do with the trunk open.
