Rear Deck From Scratch - How To

writer: Jason Ludwig Rodz

Even if your ride doesn't come with factory speakers in the rear deck, it doesn't mean you shouldn't put some aftermarket drivers back there. Building a baffle is relatively simple. All you need are some basic ingredients (e.g., MDF, fleece, resin, body filler and vinyl) and some tools like a saw and router. Here we'll show you how to build a custom panel from scratch for CA&E's classic BMW project car.


The original rear deck panel on this Bimmer had already been removed. That's good news for us as it cuts down on demolition time. As you can see, the metal tray that separates the cabin from the trunk allows plenty of depth for a set of coaxials.

Before continuing, we have to unbolt and remove the seats. Here we got rid of the headrests (who needs 'em?), which means getting busy with an airsaw. The metal brackets are sawed off on both sides.

I like to tilt speakers at a 30-degree angle < less isn't enough and 45 degrees is too much. To get this angle, cut stilts from MDF with the tops sliced at a 30-degree angle. Attach them to the base and rings first with wood glue before nailing them down.

Notice that there's a gap in between the rear deck and the seat. Fill this in with another piece of MDF. Again, grab some cardboard and create a template of the area before cutting out the MDF.

The rear deck gets its flowing shape from fleece, which we'll stretch across the MDF base and stiffen up with resin. Before attaching the fleece, get out those plates for the speaker rings and logo. Pre-drill holes so you can match them up through the fleece later. When attaching fleece, start from the center and work your way out as you stretch the material tight. Staple it down securely on the underside. Here we placed the staples approximately 0.25

Remove the plates and cut out the fleece in the mounting rings. Continue to sand around the cutouts before moving to a 200-grit sanding disc. We need to get the fleece as smooth as possible, because even small imperfections will show through the vinyl.

Now, break out the heat gun. You'll need to warm the vinyl in order to smoothly pull it over the sharp edges. Heat it just enough so it's pliable, especially when you're working on the corners, but don't make it so hot that it melts.

Custom Center Channel

Yo Yo YO, what up. Srry I haven't posted in a while but I've been extremly busy. LOL. So here is a hot tutorial coming at you from the folks at Caraudiomag.com. Its on how to completely redo the center console in your car.

Redo Your Entire Center Console - How To

Incorporating A Custom Center Channel.
writer: Jason Anderson

With surround sound becoming so popular at home, more and more people want the same sound quality in their rides. You can buy a single-DIN center channel ready to drop in your dash or you could custom mount a driver right in your instrument stack. Even if you pass on 5.1, this how-to shows you the steps to totally customize your center stack, including rerouting the HVAC controls and smoothing in your aftermarket gear, such as this Kenwood double-DIN monitor.


We performed this install in a Nissan Maxima, which comes with a plenty of room in the dash for the stock equipment. A good place for the center channel is at the top of the center stack, where the HVAC and hazard buttons are.

Pull out the entire center stack and disconnect all of the cables. Now figure out where your HVAC and hazard buttons will fit. Here in the Maxima, the HVAC controls come in a single strip, which we can reposition underneath the new head unit. The tricky part is the factory thermometer, which is just to the right of the controls. We'll get rid of a cigarette lighter and ashtray to make room for this at the base of the stack and flank the hazard and defrost buttons around it. Take apart the HVAC unit and cut the HVAC bezel so it will fit in the factory trim beneath the new head unit.

Once you've decided where everything will go, and made sure the equipment actually will fit, start cutting the existing factory bezel. Use a Dremel tool to cut the trim a little larger than the bezel that came with the radio. This makes the head unit look stock. Do the same with the HVAC bezel and relocate the buttons.

For solid and clean results, it's important to mount the equipment first and fabricate around it rather than fabricating and then mount the gear. Mount the HVAC controls and the new head unit securely in the factory brackets. Now, superglue the bezel into the trim and remove the equipment.

Now fill in the gaps with Rage Gold body filler. Smooth it out to the edges of the bezel. Remove the equipment again so it won't be scratched during the sanding process. Start with 40-grit to knock down the high spots and finish it off with 80 grit. It's important that there are no imperfections since they'll definitely show up during the primer and paint stages.

The center channel will be placed within the lines of the dash. It helps when building a frame for the material to secure to, to tape the sides of the dash and construct a frame out of MDF.

The best way to securely mount the driver is to create a ring. This way the speaker can mount from the back. Cut a ring from MDF and round over the inside edge to eliminate unattractive 90-degree angles. Superglue the ring in place.

Stretch and superglue the grille cloth in place. Make sure you pull the cloth tight so it won't sag as the resin is applied. Cover the panels and floor to protect them from drips and mix 8 ounces of resin with 8 ounces of 1/32nd milled fibers. This gives it more strength. Apply evenly and let it cure completely.

To match the rest of the interior panels, take a piece of the dash to a paint shop so that the paint could be dye-matched. It only takes a few coats.

After giving all three pieces a final sanding, it's time for primer. The Slick Sand variety can be built up and sanded very easily.

Before reinstalling the panels, stick the soft side of Velcro to the edges to prevent the panels from rubbing against the dash and damaging each other. The finished result will look completely integrated - much better than the mishmash of colors and dash kits that were in place before!

The Basics of Lowering Part I

This is part one of a three part artical brought to you by hondatuingmagazine.com

Camber 101 - December 2007 Wrenchin'

How Do You Do That Thing You Do?

There is hardly a single vehicular enhancement that is more commonplace than lowering the car's ride height. Whether it be for looks or handling, we're convinced that removing an inch or two (or even three) of ground clearance is synonymous with Honda Tuning. Over the years, there have been many developments that are designed for the specific demands of low-riding tuners. Short case dampers, skid plates and higher spring rates are all designed to help keep suspension compliant and handling in check by way of resisting the bottoming of the car or the dampers.

Suspension modification is very common today, but one should be careful not to oversimplify the suspension system's dynamics. It is quite complicated and was laboriously protracted in the name of handling balance by the Honda chassis engineers. Of course, it is expected that lowering a vehicle will thereby alter this trigonometrically dictated ballet and will generally upset some of the compromises built-in from the factory. The "alignment" of common suspension angles that compose the geometry are greatly effected by lowering and this writing is intended to bring those changes to light.

The three angles to consider in the alignment settings are caster, camber and toe. All of these suspension settings dictate important considerations in terms of handling, feel and tire wear. Caster is somewhat built-in to the chassis and is non-adjustable on a typical Honda. Generally we are not concerned with adjusting it outside of race-level performance enhancement. It doesn't move much when a car is lowered.

Cusco camber plates provide easy camber adjustment on strut suspension cars like DC5s and EP3s.

Camber is the most dramatically effected setting when lowering a car. This is the characteristic "tilt" of the wheel on a slammed car. The top of the tire leans into the wheel arch, and in drastic cases (especially on EF and DA chassis), the angle is so severe you'd swear the wheel is about to fall off. Nearly all automotive suspensions are designed to exhibit a certain amount of camber, which is measured in degrees. An age-old gripe within the Honda Tuning community is that there is no ability to adjust this angle with the factory suspension arms.

In fact, the only suspension angle to which Honda does provide adjustment is to the toe angle. This is the baseline steering angle, easily remembered if you liken it to looking down at your feet: Toes pointed in or out will simulate the toe conditions on a car. Toe is probably the most important angle we consider since it is adjustable and it's setting impacts the car the most. If the steering wheel is off center, or the car pulls to one side or the other, toe is the typical culprit.

These toe links from Cusco offer additional rear toe adjustment on the RA chassis Odyssey. They provide the additional range that is needed when lowering.
These toe links from Cusco offer additional rear toe adjustment on the RA chassis Odyssey. They provide the additional range that is needed when lowering.

When a car is lowered, the tires will toe-in or -out fairly dramatically, depending on the design of the suspension. The odd thing that happens is, the toe is impacted evenly on both sides, so when the toe is even there is no pull. Many people mistakenly think that because there is no pull no alignment adjustment is needed. Unfortunately they find out instead that their tires have worn out very quickly and need to be replaced.

It is important to realize that all cars have positive caster built-in (adjustable on some cars, but non-adjustable on a Honda). This means that when you turn the wheel, the axis of rotation is not vertical. You may notice caster to be more exaggerated on European cars. The best way to view the caster angle is to turn the wheel all the way to one side and get out and look at your car. Notice that the wheel is turned but also somewhat flopped over? Have a friend with a Mercedes S500 do donuts while you watch outside. The wheels really flop over on those tanks!
