Well thanks for the input, I'll just leave it as it is for now, on the basis of changing the sound im limited. As the CD unit is seperate from the actual stereo unit in the car, so adding in say a sub and a new faceplate etc would involve a dodgy job, cutting things etc, looks the exact same as this:
Also the car is a 53 plate yeah, but it's only covered 28,000 miles. Which is good for it's age yeah, but also the fact that in those 28,000 miles I've not had one problem, so weather the engine is bad this or that, it's served me well tbh.
