Hi all. I'm wondering if anyone has managed to get a nicer sound out of the RCD-510, maybe by changing the speakers or adding an amp?
- Is the bottleneck the head unit (which I'd like to keep as it looks nice and OEM), or the speakers?
- Would adding an amp only benefit 'bangin choons', or would it improve the R2, R4, Classic FM and 'Dad Rock' stuff I listen to, at normal volumes?
- Ditto subwoofers. Are they for anything other than thumping bass? Like adding richness to the spoken word of R4?
I spoke to an ICE retailer who suggested Infinity speakers, and adding "an amp". But before I blow £400 if anyone's got any experience / suggestions / recommendations I'd be really interested to hear. Ta'!

- oh, and if the door panels are coming off to fit new speakers, is it worthwhile putting in Dynamat type material, or is all that stuff a case of "the Kings clothes"?
