Default More power in a Cobra

Is there a way to get more watts from a Cobra 25 LTD Classic without
adding any parts?

Sure - get a 100 watt linear.
Other than that - don't expect power gains out of a radio that is built to conform to FCC specifications. If tweaked and peaked properly with the stock parts on board, one can only expect a couple of extra and dirty watts. It is better to have it turned DOWN a little bit - and then add a 100 kicker. Or more. I prefer the 100 watt - btw...

I have a friend of mine that hs a modded ('parts added') 25LTD. It S C R E A M S ! ! !

The overall audio quality, receive, and general performance can be improved over stock. Remember, a stock radio is "ballparked" in on the assembly line. A complete alignment of the radio is a must. Beyond that there are many other options as far as swing kits, audio kits, and final swaps. If you want substantial power improvement an amplifier would be the best choice. A proper tune is still needed though to set the carrier right for the amplifier you get.

What type of antenna are you using ?
The old saw of cheapest radio/best antenna holds true.

9C1Driver has it right. Proper tune and alignment and a quality microphone will work great. I had a stock radio I used out of the box for years. I always thought it talked great. After I had it peaked and tuned it was like it was a new radio. The local guy that tuned it said it was way off frequency with little modulation. It was my first CB and old Uniden 510XL. Our local tech said it was 2 watt DK with swing to 7 watts. The peak and tune puts it at 5 watts swinging to 21 watts. I was a little sceptical, because I had used it for years so I had Bob F. of Bob's CB I-80, PA check it for me when I was in the area. Bob put it on his bench and his only reply wa nothing needs done- someone already tuned it up. Proper tune & alignment is the way to go, if it had not already been done.

And Bob's is one of the few you can trust. Sounds like you have a decent local guy to work with too there squirrel. Those Uniden 510xl's are rocking little radio's for their size.
