I just bought a GE 2.1 speaker system from Jasco products and it will not play when coneected to my dell laptop. I have everything plugged in right.I used the laptop with a different system and it works just fine. With this one I can hear noise coming from the speakers but no music. And when subwoofer is turned all the way up I can hear radio in the background. Any ideas would be appreciated.


Answer
One thing you might want to check is the sound card option related to the digital audio output. Not sure what kind of speaker system you used before but try changing that option and see what you get. Also make sure the speakers are plugged into the speaker output. On my Dell, the mic input is adjacent to the speaker jack and is also the same size and I have gotten them mixed up before.

Can i connect a car subwoofer and amplifier to a PA speaker system?

I have a PA speaker system which is very loud and has great sound but has absolutely no bass. However, I also have a 15 Alpine Type R car subwoofer powered by a Kenwood 1800 Watt Mono car Amp. I would love to be able to connect this sub and amp to my PA system to create a great sound system for my house but I have no idea how to do it or if it is even possible... Can anybody help?


Answer
Yes, this can be done but things to consider is 1) How to power the car amp in your house? You could bring a cr battery in but that's only going to suppy the electrical current you need for a short time, then you will need to recharge it. My suggestion would be to invest in a "Regulated Power Suppy" to convert your house 120vac current to DC current like your car's electrical provides. Also to get the max power from you kenwood amp to you alpine car sub, you're going a power supply capable of delivering between 13.5 -14.4 volts DC which is the average range for most car electrical alternator voltage and what your car amp need to produce max power. ) Then ther's the matter of feeding the signal from your PA to you car amp. The safest way for this would be to use a "Line Level" signal say from the rec , or Record out jacks usually Red & White (RCA) type to the "Line In" Inputs of your car amp. After that it's just a matter of playing your music through your PA and adjusting the level on you kenwood to match your listening preference. Just remember when you increase the volume of the PA you may need to increase the level on your car amp as well since you are feeding a line level signal from the PA to the car amp. the PA volume control will not have and effect on the amp volume. In short what you want to do can indeed be done but there are easier ways to add the bass you want to you PA. Hope this helped you out.You may email me if you like at rudedog5876@gmail.com for some other options you want to consider.
