Hello all, apologies if I'm in the wrong area...... I've recently got a 52 plate (2002?) Audi A4 avant 130 diesel manual. It has the bose symphony stereo in it and the best sounding speakers I've ever had (it's all standard). Unfortunately, the speakers on the front right cut out intermittently over bumps/ left turns and come back on if I drive over cats eyes/ give the car a quick jerk to the right. Is the speaker cutting out issue the amp, or is it the head unit? ~I've had the head unit out to try and fit a mk6 Golf one (gave up once I saw the weird audio plug on the bose system) The speakers have now began sounding distorted too, I'm unsure if I'm killing them by having the bass flat out and the volume generally about 20 (max is 30) or if it's just the amp or head unit dying off. Ideally I would like to have a DAB tuner function or a line in so I can plug my phone in and stream DAB radio via the input. It doesn't have either of them. What are my options? Any advice? Things to look at? Common faults? I'd rather just bung another stereo in with DAB and fit the aerial (it looks like it has a digital aerial connection but may be something else?). Thanks in advance.
