Ok,i recently replaced my stock battery with a dry cell(red top). Ever since i did this I have been having issues. Lights dimming,music cutting out on low bass notes,alt belt squilling on low bass notes. I have checked all connections an everything is nice a tight an where it should be. Questions:
1.Im running 800wrms on a 90amp alt,is doing the big 3 on my stock alt going to help at all?
2.Is the battery to big for my alt to charge maybe?
3.Would adding another battery help?
4. Im thinking of getting rid of the car next spring,so i realy dont wanna put the money into a ho alt. Might there be something else i could try?
Id appreciate any help on this,thanks

What you can do is turn the volume down until you get a car you can put a bigger alternator in.

Ever heard the phrase no replacement for displacement? No replacement for alternator power. Same thing.

big 3 is a good idea any way. more battery's = need for more alt, if the belt is "squilling" it sounds like its loose or dieing.

More battery capacity does not hurt anything. But it won't solve his problem either.

its also been argued that more batterys = more strain on the alt, at least thats what every one has been saying.

I checked it and the belt is acually pretty tight. It may be my alt just slowly dying. I just dont understand why my problems started after i put a better batt in there!? With the stock batt i never had any issues. So a big 3 upgrade on a stock alt is benifical? If i do decide to replace the alt,what would you guys suggest? I did some looking an i couldnt find one for a good price. Its a 04 dodge neon w/2.0.

Big 3 will always help over stock wiring. How old is the car?

the amp is drawing up to about 60A of current. that isn't leaving a lot for the rest of your car.

if that 800 watts is a class AB amp, you're drawing even more current.

Yea,the cars an 04. Its a class d mono amp too. So what your saying is my amp is drawing 60A out of my 90a alt? If thats the case no wonder im having problems. As for the big 3 upgrade,why would bigger wire make a difference on a stock alt? Just asking... With an alt so small,its not going to be able to produce more current right?

Produce more no. Save through efficiency in your wires yes. Less resistance means more power to where it was intended.


kinda like a truck traveling on a bumpy road as opposed to a smooth one, both a mile long.

But ya, that alt won't give you much to begin with. Seeing as you're ditching the car soon anyway a big 3 is a cheaper start. Just tone down your music I guess?

Also,im using 4ga wire. If i were to do the big 3 would i use 4ga for the upgrade or a 0ga? And if i were to use 0ga would i have to upgrade my 4ga wiring too?

Check out these carts and compare the distances needed in your wire.


But I would use 1/0 ga for all big 3 jobs.

For your big 3? Depends on the car. Check the distances from the batt, alt and ground. Some can do it with only 8' or so while others use 12'. And half a dozen or so of good 1/0ga ring terminals is a good start. I gave a decent link in another thread for terminals at about $1/ea. Also, are you going to be adding to or replacing your existing wire?



Here ya go.

I should clarify.. your amp CAN draw up to 60A at full output.

At lower listening volumes, you're drawing much less of course, since every time you halve the volume, it's approximately a tenfold drop in power consumption, to a point, as the power supply is always going to draw *some* power when it's energized.

You can get one of those battery terminal kits if you wish but you're still gonna need some ring terminals. Look around for the best price. Some places want to get $4 a piece while other are far cheaper. Just let me know about the wire and when.

Checking over my wires to get an idea of how much i need. Both the grounds will be easy,but now the power wire doesnt run to the alt,its going to what may be the solinoid idk? Its running to a wierd shaped red cover and also has another small wire clipped onto it. The other power wire just goes to the fuse box. Anybody know how im going to replace this? I dont want to get in there and start screwing things up.

wiring an amplifier?
run the positive line from the amp or power distribution block straight to the positive terminal of your car battery. use an in-line fuse to protect the car in case it shorts. prevents you from starting a fire that way.

ground the amp close to where it's mounted, straight to the chassis somewhere. sand the paint away from wehre you bolt the ground wire down. makes for a clean solid connection.

oh, and the third, small wire coming from the amp should go to the radio's REM or PWR ANT line, which triggers the amp to turn on with the radio. this is a low current 12V line, so it doesn't need to be large.

You can run a positive directly from the alt to the positive terminal of the battery. Leave the stock wires be. I just did the upgrade, using the wire Paul sold me and it made a nice difference in my voltage staying up. I picked up 1/0 ring terminals at a local audio shop for $3 a piece. I had a hard time finding a decent deal online. If you can find a good deal on a 1/0 amp kit I'd say go ahead and run new wires to your amp. The wire Paul is selling is good stuff, very flexible. I ordered ten feet and honestly I may have only used 5 foot of it. My negative connections were right underneath my battery and my alt was maybe a 3 foot run to my battery.

How do i find where to run the wire to on the alt? The power wire thats on there now doesnt run directly to the alt. It looks like it runs to the solinoid and from there i have no clue. The alt is kinda hard to get to or to even see.

that's probably your voltage regulator if it's an external Vreg.

Somewhere on there, there should be a bolt with an 8 guage wire running to it. It may be covered with a plastic cap. Under it will be your bolt to connect to.

Ok, im going to have to take a closer look at mine. I wish my alt was in front like that. Yours turned out realy nice man. I see what you meant about using the side posts. I have the same battery just a bit smaller. I may do it the same way. Thanks for the help
