hi bro, me ok ok loh '
no no ... i dun meant memphis no good for SQ ... perhaps is not commonly used by people locally.. so i personally have not heard its SQ before ....
errmm... 4 years model back.... it also depends how long has he been using... cos there are cases where the amp model is rather old but it is still considered new / pristine e.g. if it was new and kept in the store...
mine to share its power and specs... perhaps then we can all give u a better suggestion or something.. cheers!
