If money is no object buy an rf speech processor,if money is tight look at an audio clipper type processor,not as effective but will give a decent boost to your audio and is much cheaper.The tradeoff will be a slight bit of distortion but very powerful audio.
Another reasonable investment if you can find one cheap is an astatic 575-m6 microphone.Gives nice powerful audio but the trade off would be heightened background noise in a noisy environment.
You could take the path of wideband audio and studio style processors but its costly,very few people on
cb have the receiver bandwidth to benefit from it,its often overkilled by individuals who think they sound good but who are deaf to distortion,a bit like grunge rockers or heavy metal freaks.
The other option is too undo the power mods and have the radio operate close too 100% modulation which is both loud and clear,with power mods done your radio will struggle to do 100% modulation.
I'm not too familiar with the cobra 29 ltd but in export radios you can also keep the extra power and beef up the audio modulator/voltage regulator circuit.
Big radio sound in my experience generally equates to crap radio sound,much better too take the path of loud but clear audio which is less stressful on the listeners ears.
