Thread: AMP hookup...

There's no point in putting two fuses inline like that -- you still get a maximum of 20A.

On the other hand, those watts ratings they put on amps are almost always overinflated. I bet you'll be fine with a 30A fuse. There's no harm in trying -- the worst that can happen is that it'll blow the fuse, and then you'll know for sure you need a bigger one.

You can power your PC off the same +12V line, if the cable is thick enough. The PC only takes a lot of juice at startup, when your amp doesn't need it. On the other hand, 30A may be insufficient for both PC and amp (especially if you use an inverter rather than a DC/DC to power the PC), so you may end up looking for a 40-50A fuse anyway. Try a car audio specialist, they're sure to have them.

I have 2 amps..

sorry... I had 2 amps

One is 600 watts (at least it says so)
and the other one is 200 watts.. (both peak)

The fuse in the 600w is 30A
while the fuse in the 200w is 15A

OMS is right, you should be good with a 30A

----
One thing I tried with the 600w amp:
It uses a 30A fuse, I installed it in my car but I didn't have a big fuse holder at that time, so I thought i could use a smaller fuse holder..
The biggest fuse for that holder i had was just 16A.. I could try it at least I thought..
Putted it in and it worked absolutely fine for over a year !! The 600w amp doesn't draw more than 16A (even not when it's almost full open, but I'm afraid my speakers won't take that, so i never tried, but i don't have to try that) (600w fused with 16A ?!?!?!?!).

someday when I was a bit less carefully I spilled some soda-pop on the amp.. Fried that thing..

Because I didn't need all that power anymore (changed cars 1 month before) I bought a 200w amp..

...

conclusion

You should be absolutely fine with a 30A fuse.

Sorry for the long post

BTW,

The more amps you think you can pull through a wire, the larger the wire you need.

a 30amp fuse is good for the larger guage wire in your car (like 12 or 10).

I am sure there is a reference somewhere that matches wire guage to amps, but I don't have it...

Amp works with the 30 fuse. Didn't full test it out, just tested with the back speakers. Works good. Only one problem, I dropped the fuse between the battery and wiper fluid container. Guess I need to go to the store again. I'm debating in hooking up the stereo to the amp or not, I know I would need a Line Output Converter. Would it be better to, or just leave it alone.

Thanks,

When I installed my 600watt inverter, I was able to find a 70amp fuse.
I was supposed to use an 80, but it worked fine.
You must not be looking very hard.

Yes, I'm in Raleigh, NC. I prefer not to take my car to an audio shop for something I can figure out on my own. Plus it is more rewarding to do it yourself. One of my main problems is that I work 4p-12am, so I'm on a 7 hour sleep time diff. Anyone who has ever lived in Raleigh know most places close between 9-10pm, well wal-mart is open till 12am.
