Problems With MY HK4000d!


Recommended Posts

ok so ive had my amp under my bed for about a 2months now,and today i got bored and decided to hook it up and wen i did i put the volume at 5 0f 35 , and added a lil bass then i made a "click" sound and the bass cut out so i took off the bass a the bass came in, ok i have stock 150 amp alt, 1 duracell 1000 amp battery, and one HC2400 in the back , one 250 amp fuse 0 gauge power and ground !

How did you set the gains? They may just be too high and sending it into protect.

Don't some amps have built in clipping protection circuit's?

Honestly, I just heard that some do. But (if I heard right and they exist), the theory would be to shut the amp down if it detects a clipped signal.

Try some other songs. Get a vid if you can.

i had this happen wiht my HK802sx, Take off the front cover and dust off your fets. and if you can, carefully dust off the board. i did this and worked just fine after that. also, i had mine with 2 hc2400s and a 200 a alt at 2 ohms bridged(its a 2ch amp) and i needed more battery power. so i would add another battery
