hi all, i just pulled out a dated alpine cd head unit out of my my96wrx all was working fine good radio and cd sound quit bassy just on upgraded standard size speakers. so ive just put in a cd/dvd/bluetooth all bells an whistles 2din unit,for one the sound quality is not as good,secondly the radio sounds all farty like the speakers are shot to bits but when you turn it on to cd/dvd it sound perfectly fine with a fairly decent sound.am scratching my head because it was fine with the old head unit. both are 4x50w.the new unit has only one sound menu which applys to all aspects ie dvd/cd/radio etc. was thinking maybe a small amp to boost the speakers if the unit is not powerfull as the old one. or maybe a new areial ,dont no really no, stabbing in the dark really. or is it just one of them things, any ideas would be great

 

Where to start, i won't bore you with the tech stuff, but the alpine unit if full of high quality parts, even down to the soldering on the board, i assume you have brought 1 of those chinese ebay jobbies, and tbh there the biggest pile of turd i have ever seen, i supply and fit audio for some 18 years now, the radio will have a poor quality tuner in it even if you got a signal booster it might not be that much better, the chassis of the unit is poor also and that leads to poor earthing,

all in all send it back and put some money towards a top quaility double din from pioneer/kenwood/sony..........
