Long hard bass amp turn off...

Battousai · Post by **Battousai** » Fri Dec 08, 2006 5:24 pm

Ok here is the whole problem hope someone can help:

First off i had my bazooka 600max amp that i got from a friend hooked up to some crappy temerary subs (2) (if i remember they were only rated for 200 watts). I had a 60 amp inline power fuse and everything was ok besides the speakers were terrible.

Next i upgraded my subs to two of the pioneer TS-W251R
subwoofers which are 120rms, 600 watt max, 4 ohm in a sealed box.

Now i'm getting light dimming(which i have read is not a real problem) and i kept blowin 60 amp fuses.I think I blew a total of 2 then the car audio shop told me to get an 80 amp fuse. Now when I get a lot of hard bass(I aslo listen to hard hitting long bass notes loudly) i will hear no bass from the subwoofers for about 5 seconds and then it would come back.One time i came home and cranked it up and i went to the trunk and looked at the light on the amplifier and i noticed that when the bass stoped it turned completely off and then turned back on by itself. I'm thinkin i should go back to the 60 amp fuse but i don't wanna keep blowin fuses $$$$.

Hope you can help!!
Thanks in advanced!

Step away from the Bazooka, I promise it will be ok.

Ok first that amp needs to go.

Second, you have the subs wired at a lower ohm load than your last set up. So the amp is using more power, and going into some sort of protect mode.

Check the rating of the fuses on your amp and add about 10 percent. Thats how big of a fuse you need up front. DON"T GO BIGGER.

Oh and you might want to find an install shop. I have a bad feeling about the one your going to. I might be wrong, But...................

That about covers it all. The fuse was to big, and you are probably running the amp at to low an ohm load.

What size fuse should i get then? if i am correct i have 3 20 amp fuses(blue) on the back of the amp. if i do the 10 percent thing u said i get a 66 amp fuse, so what size fuse should i get? Also should i get another cylidrical fuse and fuse holder again? i think its an agu type fuse.I went to the bazooka website and found a similar amp and it said the power handleing is 200x1 at 4 ohms and 300x1 at 2ohms. so with 2 4 ohm speakers shouldn't it comeout to 2 ohms? My amplifier should be able to handle 2 ohm. If i'm wrong plz tell me and explain. Thanks for all your help it is well appreciated.

You should get whatever you can around a 66A fuse. It doesn't matter what kind of fuse holder it is. Were your subs DVC 4 ohm or SVC 4 ohm?

Thanks everyone for your input i went to the audio shop and told them about melting my fuse holder and they came up with the same conclusion that JeremyC said that the amp was running at a low ohm rating so they wired my subs (svc 4ohm) into series to put the ohm rating at 8 ohms instead on 2 that it was before.So far it is great. Doesn't sound much lower in volume and my lights don't dim anymore :)
Thanks again!
