   get a link to the amp and speakers mate
   
   but you should be looking at the RMS ratings
   
   headunits internal amps arent very good, 4 x 50 watts is usually aboyt 4 x 12 rms

   No thats fine as your head unit puts out double per channel what your speakers can handle. 25W is really low though so I would get the amp AND uprate your speakers!

   hes read it literally as the speakers want 25, and the headunit is giving 50....
   
   the headunits wattage rating is its peak power not its rms... its giving the speakers jack shit all but then they might be sub-par speakers and then i really wouldnt bother amping unless your upgrading speakers at the same time...

   no you wont need an amp
   
   headunits only produce around 17wrms per channel
   
   but its not worth buying an amp for a set of coaxial speakers of such little rms output

   Tbh, I would not bother amping 25 RMS speakers. Upgrade to some comps and run an amp
