Amplifier needed for CB external speakers

Any suggestions on how to amplify the volume on 2 external speakers that are connected to my Cobra 75. I am using two 6 inch JL audio stereo speakers.

I prefer not to run the typical amplified external speakers that one can purchase for a CB radio. I prefer the stealth look of having the current setup as the speakers are flush mounted in my dash.

Thanks.
Chris

Interesting you should mention this - I just finished running the wires for that last weekend. Same reasons - stealth install in factory locations I am actually using the typical CB radio speakers that connect with the 1/8" connectors. Left dash speaker is for the HAM radio, right dash speaker is for the CB. I have yet to hear them powered up, so I might be looking for the same sort of thing too if they're not loud enough.

Are they running through an aux input in your head unit? If not, is that out of the question?

find a cheap amp on ebay, get a 1/8 to rca adapter an hook the cb to the amp and the amp to the speakers....

You may need to put someting in betweem the cb and the amp to attmuate the signal a little bit...

Same theory of people wo want to run an ipad or ipod instead of a head unit...so may gooe that fr soe more info.

There is a nice CB shop on Essex Street in Rochelle Park/Maywood Just West of Route 17. If you are coming from the north (heading south on 17) take the Essex Street Exit and head right. It is across from the Harley dealership. They will have what you need.

I'm interested in this topic, but the path I'd like to take is a little different. I'm not an audiophile so I may be using the wrong terminology, but I want a multiplexer. I want something smart enough to be able to take multiple input streams and be able to prioritize them. So say you have the radio, cb and some other device like a bluetooth phone. If the CB comes on, it should cut in and be used as the source instead of the radio. The bluetooth should override both.

I'm guessing these products exist but I know I can do this with a carputer if necessary.

If you have a decent radio it should have a Jack for an AUX speaker. I have a Cobra and it does. The speaker that came with it is very loud....

I decided to go the route of purchasing a mini amplifier, 200w made for a motor bike, and will use that to boost the power to speakers. Thank for the advice to use a 1/8 to RCA adapter to amp. This should do the trick.

I am also running the device in the link below...this is what you maybe looking for. It works nicely to mute the stereo when an incoming/outgoing call from my CB radio is recognized.

Neat device but still requires you to have an audio interrupt on your stereo so without a slightly fancier head unit it looks like that isn't really doing anything (at least from the install instructions on the site). Audio interrupt features are becoming rarer now on aftermarket head units since the introduction of built in and optional blue tooth.

Not trying to rain on anyone's parade, but I was eager to take a look at the device for thoughts of use myself.

Didn't know that most manufacturers were eliminating the audio interrupt input from their head units. Fortunately, the new $100 Alpine head unit I just purchased still had this feature. Sounds like it's worth investigating compatibility prior to purchasing the audio interrupt device and/or head unit.
