| Question: Woofers are making crackling popping sound, please read details.? Posted: 20 Sep 2016 08:45 PM PDT Error #1: Pioneer does not make a GM D1906, but they make a GM-D9601. If this is what you have it is rated 1200 watts rms @ 1 ohm. 800 watts rms @ 2 ohms, and 400 watts rms @ 4 ohms.. Error #2: You do not "bridge" speakers, you bridge amplifier channels. Bridging is electrically connecting two channels together to create a single more powerful channel. Obviously you cannot bridge a monoblock amplifier since it has only one channel. Error #3: NVX does not make a XQW112. Did you mean the XQW122 instead? If so, it has dual 2-ohm voice coils and it is rated 600 watts rms. Error #4: What you apparently did is wire the voice coils in parallel to make each sub 1 ohm. This is NOT called bridging, it is called parallel wiring. As you'll see, this was a mistake. Error #5; If you then wired the subs together in parallel to each other the final impedance is 1/2 ohm. Your amplifier cannot handle a 1/2 ohm load and it will eventually overheat and go into protection mode. The crackling and popping occurs because the amp is trying to make more power than it is designed for and the signal is "clipping". This is the worst type of distortion and can destroy your subs quickly by overheating the voice coils. Solution: What you need to do is rewire the voice coils of each sub in series for 4 ohms per sub, and then wire the subs in parallel to each other for a 2 ohm total load. You cannot get down to 1 ohm with a pair of 2 ohm DVC subs. The choice is 2 ohms or 8 ohms. At 2 ohms your amp can produce a maximum of 800 watts rms. The subs can handle 1200 together, so they will be a bit under-powered, but you wouldn't be able to listen to them at full power anyway without damaging your hearing, so no worries there. Just rewire the voice coils to series configuration and wire the subs in parallel to each other and your problems should vanish. Feel foolish yet? Don't worry, you're not alone. Lots of people make these mistakes when they do not understand impedance, simple wiring concepts or basic terminology. Now you know better. Good luck. Hopefully you haven't damaged your equipment already.  |

| Posted: 20 Sep 2016 06:31 PM PDT (A) Boss and Planet Audio are cheap in price because they are very low quality and do not produce the advertised output. I recommend that you avoid these brands unless they are is all you can afford. (B) You are quoting peak power ratings. Your "1500 watt" rating is peak power and it is more or less meaningless. What you should refer to is average power output expressed as WATTS RMS. (C) You're probably looking at the Boss AR1500M. Boss rates it at 700 watts rms at 2 ohms, but in fact it can really only produce about 400 watts maximum without blowing the fuse. that's OK though because your pair of MTX subs can only handle 400 watts rms together anyway. (D) A better quality amplifier than Boss or Planet Audio that is reliable and can actually produce its rated power reliably is the JVC KS-DR3001D which is truthfully rated 400w rms continuous output. It can be had from online retailers for about $110. A far better quality amp would be the Rockford Fosgate Punch P400X1 that produces a clean 400 watts rms @ 2 ohms and is very sturdy and reliable, but it costs about $200. |
| Question: Questions about ground wiring power inverters? Posted: 20 Sep 2016 06:24 PM PDT First off, forgive my ignorance on the subject...this is why I'm asking you guys after all... Basically, I have a deep cycle battery I want to run my 2000W inverter off of. I have a few questions related to ground the wires, etc: Is there TWO attachments on the interveter (one that is a negative terminal that runs a ground wire to the battery), and a chassis ground connection? If so, why is the inverter chassis ground connection so much smaller than the negative ground wire that goes to the battery? Don't I have to use the same cable gauge for the negative terminal as I do for the chassis terminal? There may be misleading information I just typed because I don't know squat about it as of now. Just trying to build the bigger picture at the moment. Thanks for your help |

| Posted: 20 Sep 2016 04:52 PM PDT Yes. There are several devices, but if your car has bluetooth linked to the audio system for phone calls, it should also work for music. If not, there are cheap devices that will do the job. The Aux input in my wife's Ford is hopeless so I bought a device that plugs in to the lighter sockets. You can link to it by bluetooth or by aux cable or you can plug in a USB drive or an SD card with music on. You tune you car radio to an unused frequency and then tune the device to transmit FM signals at that frequency. If you want to play music from your phone, you can link it by bluetooth and select your music. The device picks it up through bluetooth and then re-transmits it in FM to your car radio. We use a USB memory stick with about 200 hours of music on it, set to random play.. The device lets you jump tracks. It will even let you jump between different play lists on the same USB drive. You don't have to look at it - just reach down and press a button. |
