Kick As Speaker

"I recommend this speaker to anybody; I have had this speaker for approximately 3 years. It has been the best one out of all the others radio shack offers. I use this speaker for a police scanner and sometimes transmissions come in low to where if you had a regular speaker without being amplified, you would probably have a hard time listening to what they were transmitting.

Returned it and powered replacement speaker directly off my truck battery in the RS parking lot. Replacement speaker did the same thing! RS store refunded my purchase price.

"I bought this amplified speaker on the good reviews it had. Well, I had the same problem one other person had. It would power up and then turn off and no sound. It was late and I didn't want to go back to the store, so I took it apart. Turns out it was a bad solder joint on the audio input jack. I …" Read Full Review »

"The catalog #21-541 Amplified Mobile Extension Speaker is pricy but well worth it. Recommend a 12 volt in-line noise filter to remove any ignition or alternator whine noise (discontinued from Radio Shack - but available at any auto parts store). "
