help! radio/speakers acting up

ok recently when i play my music, not too loud, when the bass ‘hits’ the sound will just go dead, like i dont have enough power to pump bass or something, not sure quite how to say it

things i thought of

shitty battery/alt
shitty grounds
shitty speakers

any ideas???

you have a cap? when my bass used to hit in my eclipse it would actually shut my car off if i was idleing at a light… that was my fix… turn your sensitvity down a hare on your amp… it will draw less power

no amp, stock everything minus a jvc head unit

speakers probably are overdriving themselves
