speakers all seem to have blown out

[Merocks]

leganza is at 123k...evertime I raise volume..i get bad feedback..i like to bump my music but the bass is so bad its embarassing..is it expensive and alot of work to change out speakers? thanks for everyones help by the way!

also the original radio works fine, but sometimes the display on radio doesnt turn on at all, but radio continues to play music..is radio going bad?

your best option would be get new speakers and run the speakers of an amp instead of headunit because head units only destroy speakers, the amp uses all the speakers potentioal

[benzino]

you don't need an amp, many modern head units are powerful enough

for a good head unit and 4 quality speakers shouldn't set you back more than 200$
factor in some more if you need to have them installed.
the key is to look for speakers with high sensitivity i.e. +91db

if you want to run a sub, factor in another 200$ for the sub, amp and wiring
