SOUNDS THAT KEEP UP WITH YOUR HARLEY

[vc_row][vc_column][vc_column_text]If you own a Harley Davidson, you already know it is loud. If you own a modern Harley Davidson, you know that the sound system is lacking. Working with technicians at Harley-Davidson, our retail partners at Arc Audio have designed a system that takes your tunes up to the level of your exhaust.

At SRQ Custom Autosound, we carry the full range of Arc Audio systems for Harley Davidson bikes, which include five package systems, as well as a la carte parts. As a retailer and technician, I love that all of these kits bolt and wire into the bikes without having to make new holes or cut wires on the bike. The kits start off with a drop in speaker replacement and amplifier upgrade, and from there offer several speaker upgrades while keeping the same powerful amplifier. The Arc Audio KS125.2 Mini is the heart of the system. This amp kicks out 70 watts per channel, nearly seven times the power of the factory system.

The guys at Harley Davidson give you a pair of 5.25″ coaxial speakers from the factory. I will say they are better than most factory car speakers, but they are still a .99 cent speaker at best. The Arc Audio speakers bolt right into the factory locations without modifications. Need more? A funnel-like adapter allows us to mount a 6.5″ speaker to the existing location for even more sound.

Our recent installation of the kit is pictured below. To really optimize the sound, we took it beyond the top level MPAK5 and used a pair of Hertz Hi-Energy coaxials. Using the spacers from the kit, the speakers bolted right in. We also decided to beef up the wiring between the amplifier and speakers, with all the connections soldered. For even more durability, we swapped out the included mounting for a set of aluminum brackets I made. These brackets attach to unused threaded holes inside the fairing and allow us to bolt the amp in place using stainless hardware and not modifying the structure of the bike.

FORD EXCURSION CUSTOM SUB ENCLOSURE

[vc_row][vc_column][vc_column_text]Our first feature article is going to feature a recent build in a Ford Excursion. I have built this enclosure a few times, always with great results. The idea is to create something stealthy that will fill in the need for sub bass without attracting attention from thieves.

Whenever possible, we try to maintain original equipment, like the spare tire, but in this vehicle, the spare isn’t very practical. Weighing in over 100lbs, it is hard for one person to change alone, and even then the factory jack won’t get the thing up in the air safely. Our first step is to remove the spare and take measurements. We want our enclosure to be slightly smaller than the spare so that there won’t be any suprises when we fit it back in later.

After I have taken measurements for our subwoofer enclosure, I build three wooden discs. All of them have the same external diameter, two are solid and one is a ring 1.5″ wide. The first disc and the ring are attached with several sticks to create a shallow barrel.

The barrel is wrapped with 1/16″ wood called chip-board. The inside of the barrel is then reinforced with several layers of fiberglass mat and resin.

The baffle for this subwoofer enclosure is made from the third disc. The subwoofer holes are cut out and the port is attached. The baffle is bonded to the rest of the enclosure and the corners are rounded over with a router. Finally the enclosure can be carpeted and installed. We used the threaded bolt from the spare tire to mount the enclosure without having to make any modifications to the vehicle.

For the final touch, the original tire cover slips over the enclosure and conceals it from prying eyes.
