Does anyone know how many amps my alt is, or where i could find out?? and how many amps would be drawn from a 2000 watt Leagay LA1990. and would i need to add a new alt or battery like everyone else is talking about? I got all my system stuff, but havent got it hooked upi yet because they want $90 to install it FROWN.....so im pretty much just wondering if this is a problem that im going to face....i have a 2000 explorer 5.0 V8

I couldnt find a 2000 5liter but i found a 4.0 and just like my 2003 it has a 130amp stock alternator. I dont have any knowledge of legacy amps. but my 500 watt phoenix gold amp can dim the light in my 2003 ranger with a 130amp alt when it idleing. so i would assume for a 2000 watt amp you would at least want to beef of your battery i dont know if it well be nessicary to change alternators someone wel well have to get that one.

Well the 4.0 liter is a V-6 dont you think the V8 would have a bigger alt? and does anyone know where i could find out how much bigger? and how much draw that amp will use and how many amps will be left to run the other electrical componets?
ttocs on 12/10/2003 15:10:23
a 2000 watt legacy would draw maybe 5 amps.... Just kidding, I hope it does more but if you want to know for sure look at the fuses that are on the amp and you will get an idea. I bet it is around 40-60 amps...
i just reviewed the post, is "leagay" a typo? please say it is.

LOL ttocs..
according to the diy article Alternators and Charging systems By: xplicitblitzboi , to find the max amp pull of an amplifier, divide the number of max watts by the voltage your system puts out.. for example a 2000w amp at 12v would pull (2000w/12v=166amps)
at 14.4v it would pull 139amps max.
Why not install it yourself? if you have any questions, you know we will help you out.
you have a 130amp alt.

yeah, its a typo ttcos.....is legacy a bad amp?? should i get another one? ive heard a few ppl say that there not very good in other posts after i had already bought it........the amp is 60amp fuses. I really do want to install it myself!! but it seems hard.... and i dont want anything to go wrong!
movadoman2001 on 12/11/2003 01:13:32
Also....i have all the wires exept the remote wire, is there anywhere i can just get that and not have to buy a whole other kit? or is there any kind of wire i can substitute for the remote that will make the same kind of connection?
uochronos on 12/11/2003 01:59:36
As far as a v8 haveing a bigger alt i dont think that has alot to do with alt size... my 4.0 V6 puts out more hp then alot of the 5.0 v8 fords have. and the only choice for that year of explorer/ranger was a 90 or 130 amp alternator as far as i know. so i assumed the 5.0 v8 would have the larger one since my 4.0 did:)
cplkittle on 12/11/2003 07:19:17
a remote wire is usually just a 14 or 16 ga wire.. it dosen't carry much current, only 12v to let your amp know when to come on. Any wire will do 16 or 14 ga.
If the $90 included the wires, I would say go with that, but you mentioned you had them already, 90 is pretty steep.
It is very simple to do it yourself, you need your power cable (20ft)
RCAs (15-17ft), ground wire (3-5ft) and remote wire.
Run your power and your remote together on one side of the car-either above the doors behind the trim, or under the door trim on the floor. Do the same for your RCAs, except keep them away from your power wires to avoid feedback or 'whining' from your alternator.
When you get everything to the back of the explorer, simply connect your rca imputs, your remote, ground, and power..
Find a good place for the ground, my favorite place is under one of the rear seatbelt bolts. scratch a little paint off of the body where the bolt hole is, strip off about an inch and a half of insulation from your ground wire, and either drill a hole beside the threaded hole and put half of the stripped wire into that, or simply Y the strands to go around the bolt, and tighten the crap out of it.
hook up your speakers and you are done!
ALWAYS disconnect the battery during an installation, one wrong move and your hot wire could either arc through the carpet leaving a nasty burn, or worse, hit a speaker terminal on your amp-frying it.
movadoman2001 on 12/11/2003 10:04:08
uochronos you were right, i called Murrays auto parts to see if they could tell me and it is 130, so what would i need to do? and a bigger bat? how much would that help? i have a 12v now (get a 14.4?) or a bigger alt? but that seems costly, is it? AndNO that installation price doesnt include wires! I told the guy i had all the wires i just need them ran to the amp, he said 79.95 +tax and another place i called wanted 80!! i cannot believe its so much.....like 2 years ago i got my grand prix wired for $55 and that included the wires, even though they it was only an 8 ga power, but still. SO can i use just a regular 14 ga speaker wire as the remote?? (if i were to attempt to hook it up myself)
cplkittle on 12/11/2003 15:19:56
speaker wire will work fine, there is no load on a remote wire, and it carries no sound affecting currents.
Personally, I would wait and see what kind of dimming occurs when you get your system in. Minimal dimming may require a slightly larger alt or slightly larger battery. Moderate to heavy dimming may require both.
The numbers I gave you for your amp concerning what it will pull are maximum amps (amp maxed out on gain, stereo running wide open) I am not really sure what it will pull at an average level, but your factory setup may not be that bad off. There is nothing wrong with 'preventative maintenence', but there is a balance between that and not fixing something if it isn't broke. I would set aside an extra $100 (or what you would save installing it yourself) for a 'Just in case' scenario if you had to make a power supply upgrade after you see what your system can handle to begin with.
I am running a 600w amp for my subs, a 150w amp for mids, and only if I am on the brink of blowing a sub or an eardrum (which ever goes first) with the volume level, my headlights dim a little, but that is with the lights on bright and the heater fan running as well.
I know that is only half of what you are running, but it gives you an idea.

" the amp is 60 amp fuses " Not sure I get your meaning here...
Is that 60 A., total or more than 1 fuse at 60 A., each?
Swez
movadoman2001 on 12/12/2003 12:16:27
There are (2) 30A fuses
Tray on 12/12/2003 12:27:44
You should be fine.
As long as your grounds are solid, and your battery is stable, you should have no problems with your alt. Even an 85 amp ford alternator would be fine with that legacy amp.
