Only Getting 6 Volts, Need 12

Well the guy who had my eclipse before me had an amp and sub kit installed so all I had to do was throw my equipment in.

The only problem is its not getting enough juice. Theres a Stero Shop like 2 miles down the road from me and they were kind enough to just hit it with a multimeter. We quickly found that it was only getting 6 volts to the +12 on the amp. Everything (includeing the remote signal) was good.

So we figuered it was a fuse. Today I traced the line (PAIN right in the ass... only 15 degrees out right now) and I have found a little fuse box in the line that has enough room for two fuses.

Now, how do I know what fuses to buy? There are no markings on the box ANYWHERE. My guess was to get a 20 amp fuse but there is two slots. Do I get two 20 amp fuses or two 10 amp fuses?

Any help would be great.

Thanks.

Must be a really small power cable, what gauge is it? 2 20 amp fuses wont be enough. What amp do you have?

I have a xm-2002GTR (http://www.xplodsony.com/xplod/amplifiers/XM-2002GTR)

I dont really know what to buy but from what I know most people say 20 amp fuse.

Oh ok, that amp might...put out 200 watts. But anyways, You are talking about the fuse that goes in the power cable coming from the battery right? If so, a 20 amp fuse is waaay too small. And again, what size wire is it?

Yes the fuse box is right after the battery, as for the size of the wire. Its pretty fat. My guess is going to be standard guage for running equipment. I cant tell what anything is... its not marked and the guy I bought it from does not remember. sorry i cant be any more help on that lol.

Here is a crappy cell phone pic I snapped of the fuse holder:

Looks like 10 or 8 guage. Looking at the specs you should be ok with 30's.
Or you may want to get a new amp kit designed to pump power to a 1000w amp and has either a stationary fuse block or a in line tube fuse.

Looks like an 8 gauge, maybe even 10. I would go with it being a 10 gauge. That fuse box only holds one fuse, its way too small to handle the job. What do you think nilla, an 80A fuse?

So I should get an 80A ?

80 may be a bit too much for a amp..if you get a surge and the onboard electronics are not designed to handle 80 amps you'll fry your amp. Besides the factory alternator is only like 70 amps.

well i took a 20 amp fuse from the AC slot and put it in and nothing happened... My guess is it still needs more juice for the amp right?


The site says:
Current Drain at rated output (A): 48

Does that mean I should look for something like 60A? I looked around and most amp wireing kits for over 1000W use 100A fuses. Should I just grab one of those?

Get a whole new wiring kit. Go with a 4 awg wire, and a 60a fuse, you should be fine.

Something like this. It comes with a 100a fuse, but I would buy a 60a and use that instead.

I would throw that poo poo mess thats in that car in the trash and get a new power wire kit. Get 4 gauge since thats what that amp is desinged for. As for the fuse size is doesnt matter too much, as long as it isnt some little poo poo. Just get a good power wire kit that comes with the wire, fuse box, and fuse.

LOL, man i should have looked at the amp first before babbling on. Ai agree with the previous posts, go with a 4gauge wire kit. A 60a should be more than enough for you. I only mentioned the 80A cause I kept frying the 60s in my other car.:grinyes:

Well thats actually what I ended up dooing. I went back and figuered I might as well just buy a new block.

Well, after installing it I am still not getting the amp to turn on.... Really sux.

I guess ill just saying fu©k it untill its a bit warmer out.

How old is the amp? Does it go into protection mood or will it not get any power?

The guy at Stero Shop said the power line was only feeding 6v and it was most likely the fuse.

I just replaced the whole thing and got a new fuse box with an 80A fuse in it. I bought the AMP last year, used it for a month, and then I sold the car it was in and it has been sitting in its packaging on a shelf in my closet since then.


UPDATE
I just had a small breakthrough with it. I was playing around with some settings on the back and it lit up. All the blue LEDs came on, and it did not go into protected mode. It stayed on for litleeraly a second but the ground wire slipped out. There was a lot of tension on it so I am checking that right now.

Well, I now have power to the amp.... It lights up and its not in protected mode but, the subs are not hitting. I played around with some settings on the amp and the head unit but still a no go.

Any ideas?

How hard did you expect it to hit?

Do the speakers work at all? Make sure you have the positive and neg. hooked up correctly. And also that you have the correct ohms going to the speakers and amp.

Bingo, make sure they add up. I used to run shit willy nilly but after learning a bit more about electronics i quicikly shanged my whole setup.

Got it, I found to other leads comming up from the wheel well... Plugged em in the amp and boom!

Can hear me coming from miles... lol King kong in tha trunk.
