On the main current draw lead on your stereo. 12 volt side...

Hi guys had another crack at it tonight before i ordered the capacitors and it was a success. I wired it direct to the battery giving out the 24v to ground so as not to drain one individual battery and the connected a 15A fuse in series with the 24v input before putting it through the convertor and everything worked as it should! Thanks everyone for their time and advice
I suspect the 24 volt supply was dropping with a load.

Check for a bad connection somewhere. A resistive joint will drop a lot of voltage under load
