Usually the very first upgrade anyone considers making to their OEM car sound system is to add a subwoofer. It really isn’t surprising since OEM speakers are simply too small and not of sufficient quality to accurately produce low bass frequencies. Subwoofers provide the most immediate improvement one can make to a car audio sound system. Consequently one of the most frequently asked questions is: “How do I select a subwoofer?”
Actually, your selection will depend on several factors such as your personal preferences in music, your budget and available space in your vehicle. The amount of space you have to dedicate to your subwoofer’s enclosure should be the first thing you consider. In the majority of cases, this decision narrows the field very quickly. But what if space is no problem?
Subwoofers range in size from 6” to 18” in diameter. Most are round in shape but in recent years the new square shapes are becoming more and more popular. Materials used in the speaker cones can be made of treated paper, light metals such as aluminum and even various types of composites. Paper cone subwoofers tend to sound the most natural and true to life but paper is the least durable. Aluminum Cone woofers were one of the best materials to use for quick, tight bass response (sound quality applications-SQ) because they produced very low frequencies in small sealed boxes. There are some very good musical subwoofers today that offer excellent sound quality while also presenting exceptional SPL (Sound Pressure Level – An acoustic measurement of sound energy, typically expressed in dB-SPL).
I could go on but if you are considering buying a subwoofer for your vehicle, I strongly suggest you click thru and pick up some tips to make decision making a bit easier.

Does your Dog Have Parvo Virus?
What exactly is parvo virus, what dog parvo treatments work, and how is parvo virus spread?
Parvo virus has been around for the past 30 years. It was initially identified in 1978 and within two years it spread over most of the world, causing devastation in its wake. Every different species has its own parvo virus and it cannot be spread outside of the species, so although it was originally thought that canine parvo virus could mutate into feline panleukopenia, a feline parvo virus, it is now know that there was no truth to this.
Although parvo virus cannot be spread from a dog to a cat or from a bird to a cat, it can be, and is commonly, spread by contact. For example if your cat happens to wander through your neighbor’s yard and picks up the virus on her feet, she can bring parvo virus into your home and your dog could be infected in this way. Unfortunately, the puppy that we acquired recently from an animal shelter came down with parvovirus. She had all of the classic dog parvo symptoms, yet we did not realize what was wrong. We took her to our vet and parvo treatment was commenced immediately. After a four day stay at the veterinary hospital, our puppy was ready to return home. But we were lucky. Our puppy was fortunate to have a parvo cure, but if you don’t treat parvo in the early stages, it will prove fatal (and very quickly).
The parvo virus works in one of two ways – through the heart or the intestines. The intestinal infection is picked up by an animal through oral contact with contaminated feces. In other words, a dog has to come into contaminated feces from another dog. The intestinal dog parvo symptoms happen when the virus attacks rapidly dividing cells in the intestinal crypts, lymph nodes and bone marrow. This allows normally occurring bacteria from the intestine to enter the blood stream make the animal contagious. The virus is shed in the stool for up to three weeks making this disease very contagious to non-vaccinated pets.
The cardio form of this infection is often seen in puppies that are infected from the womb or shortly after birth. It is well worth noting that the cardiac form of CPV is not as common since the mother passes immunity on to her puppies from birth. The parvovirus then attacks the heart in the infected pup and death results shortly thereafter.
Dog parvo symptoms are usually present within 3 to 10 days of contact. They include vomiting, lethargy, diarrhea and fever. The diarrhea will cause severe dehydration and secondary infections. Rather than dying from the virus itself, it is usually the secondary infections that kill.
A veterinarian will recommend that you get your pet vaccinated against parvo approximately eight weeks after the puppy is weaned. With the prevalence of this virus and its ability to kill, some precaution should be taken to protect your dog. Get your puppy vaccinated – we speak from experience!
But vaccinations don’t always give full coverage. Survival rate depends on how quickly parvo virus is diagnosed and treatment is begun. If it is not caught early enough, the usual conventional treatment is an IV through which fluids are pushed to re-hydrate the dog more quickly. In addition to the fluids, antibiotic and anti-nausea shots may be given intramuscularly. With the proper care the prognosis is good, but without it your dog is sentenced to an early death.
You can also buy natural treatments for dog parvo virus. But whichever type of parvo treatment you choose, choose it quickly. Do not delay in treating this deadly condition. You can use a home remedy for puppy parvo, but remember that a dog can die within hours of the first parvo symptoms appearing.
