  • Tech Terms Demystified: Impedance

    Impedance is one of those tech terms whose meaning is just close enough to its general definition to cause some confusion. In everyday language, an impedance is a hindrance — an obstacle to be overcome. Electrically, impedance is a neutral term — part of the physical properties of electrical...

  • Top Down Sound, Part 4: Equalizing the audio system in a convertible

    Jeff and I meet at the Crutchfield Research Bay for the final system tuneup. In the last installment , we set the crossover points and adjusted the gain structure in the Sebring's system. Now, we've borrowed an AudioControl Real Time Analyzer (RTA), a complex little box that's used to measure...

  • No Audio from PS3

    I don't normally post questions (I try to figure it out myself...BUT) I know there's been similar questions on this subject, but I'm hoping for a direct answer to my particular problem. First off, I recently took the plunge into the Home Theatre Audio world and my problem is getting sound from my PS3...

  • My Top 10 Car Audio Myths

    1) I don't need a subwoofer because I never listen to loud music, just classical and jazz. Subwoofers go great with heavy metal, rap, and other types of high-impact music, but they're not just for people who like to turn it up. In fact, a well-tuned subwoofer adds depth and richness to any type of music...

  • Are you sitting on a wealth of untapped power?

    In my last post , I discussed the concept of bi-wiring. Although bi-wiring doesn’t increase the amount of power going to a pair of speakers many folks I’ve spoken with felt there’s a noticeable improvement in sound quality. That brings us to the subject of bi-amping . If you’ve purchased a seven-channel...

  • Re: receiver shuting off

    First, I assume that you are using the preamp outputs on the receiver to feed the signal to the amp. Secondly, I would imagine that you are using the remote turn on lead coming off the Kenwood harness. Now, you may want to check these and the receiver’s connections to make sure that none are loose and...

  • Re: No RCA output connectors on Jensen head unit?

    I just happened to notice that the GM-6300F is a 4 channel amp. Have you checked to make are the high pass filter is not active on the amp? Since you have checked the wiring and the head unit setting, then the amp is the last place to check. If this does not fix it, then you may need to check with a...
