After building his enclosure he wanted us to also do the install on his car. The car was in a state of chaos from the previous owner so we had a lot of clean up to do. Andrew

There is a complete layer of 1/8" CCF under the MLV in the hatch area. CCF /MLV /CCF is ideal, but unless there is a lot of space in the trim panels - true for many trucks, moving the MLV even 1/8" out from the inner skin will make the difference between getting the trim panel back on and not. I shoot for adding CCF where it will fit and be compressed slightly when the trim panel is reinstalled. That holds everything tightly in place and avoids the possibility of MLV rattling against the sheet metal. In most cases, a barrier layer on the inner skin will do the job. This is especially true if there are speakers mounted in the doors since the barrier layer acoustically reinforces the baffle. Sometimes this position isn't possible because of the way the inner skin and trim panels fit together. Mini's, newer Mazdas and a few others have large plastic inserts in the center of the inner skin that aren't flat enough for this technique to work. Outer skin placement is a good choice if the inner skin won't work, and the access holes are large enough to get to the outer skin. The advantage of outer skin placement is that it blocks sound from door mounted speakers from leaving the vehicle - good if you don't want to be heard.

The CCF and MLV are just laid on the floor - gravity, seats, trim and carpet hold them in place. On vertical surfaces or horizontal surfaces where they might move around they are anchored with Velcro strips. We would have liked to remove the factory deadener on the floor. It's a very thick layer of asphalt. Cleaning it out would have added another day to the project and we didn't have another day to add. Sometimes you can remove asphalt pretty quickly with dry ice, but it usually takes a heat gun and a lot of scraping then cleanup with mineral spirits. If at all possible, remove asphalt. If you can't, adding CLD Tiles to any resonant areas of bare sheet metal is the next best thing. If the factory material is something other than asphalt it will be almost impossible to remove and there really isn't any reason to do. Again, supplement with CLD. The doors had 5 CLD Tiles added to the outer skin and 1 or 2 added to the inner skin. Packing the space behind the side impact beam with EBR turns the outer skin into two distinct panels. We centered half the tiles above and half below the beam.

Not sure what you mean - this was door / mlv / ccf too. The ideal would be a sandwich with CCF on ether sine and MLV in the middle since the sheet metal inner skin and trim panel are both hard surface from which the MLV should be decoupled. Anything other than that is a compromise and doors almost always require them. If you get a layer of CCF and MLV between the inner skin and trim panel, no matter which order, you'll get a good result. I seriously doubt that it is possible to detect a difference based on order.

Here are some pics of my Wheely King Monster Truck. I'm running the stock electronics. I've got a crawler conversion in it. Most noticeable are the Juggernaut rims and tires. I narrowed the rims by cutting the inner bead mount of the rim, reversed it and slipped it back over the rim shell. This also gave me the clearance needed around the knuckle. I opted to leave the steering stock for a more scale appearance. I working on some adapters to mount the wheels. Let me know what you think.

Yes, how does 2.12ft^3 @ ~33hz sound.

The BL will perform much better at that tuning than an HDC3. The HDC3's are made for tuning 38 Hz+ due to their high inductance, which makes them great for SPL scenarios but low tuned daily is a different story.

It could be the alternator. Just because it's "rated" at 220 amps doesn't mean anything. It honestly sounds like the alternator isn't able to keep up if the wiring is good.

last sets....i promise lol someone else's photos

Nice speakers very aggressive without being overly aggressive maybe "musically aggressive" but not fatiguing

Got some more

All done. Just need to drop in the terminal. Andrew

well i ran street beat (30 second average on music) and peaked at a 149 at 39 hz lol aint in the 50s but i dont care who you are a 149 that low hurts!
