My bro and a friend used to have a Sony Explode (I assume this is the Sony HU that your referring to?!?) ... it's not a bad HU... but I still prefer Pioneer HU's...
yun ba yung cd ipapatong mo instead of inserting it to a slot ? di ako familiar sa
mga Sony head units saka Explode lang yata ang high end ng Sony . If you are ending
up on a system soon , sa 21K na budget mag Pioneer na lang ako , mas maraming
functional features pa compared sa Sony sa level na model nito .
