I just had my speakers changed, added a amp and woofer. Just wanted what do you guys think and would there be anything to add/improve advice.

HU - Sony CDR-X 5610
Front - Peerless 6.5" component
Rear - Generic 6.5" mid bass
Boot - MBQ 12" woofer in a box
Amp - Orion xtr 475 with built in tuneable Xovers.

The 4 channel amp powers the fronts and woofer and the HU powers the rear fill.
Sounds great but still being tuned and hoping for it to get better.

Sound deadening to doors and rear panels along with quality cables.

Looking good though

agree, as much sound deadening as you can afford mate. ebay has some for about 50 quid for 30 sq ft, which would help with teh rears and front doors etc
