i was wondering if having auxillary lights, an alarm system and an amplifier will be too much stress on my poor little gt-s and if it was a not so safe idea to do so. also was wondering if anyone else has a setup like this nd how it works for them. just a little worried that having 3 extra items running off the battery would cause an issue. thanks for the help!
doubt it unless you were running a redicliously large amp(s) :lol: How much draw total in watts are you talkin'? -K
hahah sorry but i really don;t know. its all just future ideas. i have the alarm, do not know by who or what model. came with the car and no books. the amp would be less than 1000 watts for sure. and the auxillary lights wouldnt be more than 65 i would assume. just more so worried about having all the relays, where to place them and if they will interfere with one another on the positive terminal. i know you can solder them to one connection, but i do not have a soldering gun nor the knowledge of that. so its just pre thinking right now. but want to make sure it is feasable before process!
hahaha if I had to guess, the speaker/amp would be the main draw in your scenanario ~1000w, a cap with the amp will help the alt if you're seriously worried about it. -K
Depends what you need. You could get high amp altenators that go 100 - 150 amps or more. The stock toyota alt is 70 amp. The stock alt fuse is 80 amps so if you get a 100 amp alt I'd put a 110 amp fuse in..... If you check down in technical in ST162 charging system at idle with no load on the system it should be putting out 10 amps. Under full load (with high beams on and heater blower at max) it should be putting out 30 amps. So you still have and extra 40 amps to power accesories. Even if there are occasions where you draw more than 70 amps the system will still handle it for a while. Say you were drawing 80 amps and you battery is rated for 100 amp hours. You would draw 70 amps from the alt and 10 amps per hour from the battery so with a fully charged battery you could power the car for 10 hours. But at some point during that 10 hours if you drop down below drawing 70 amps then your starting to charge the battery back up. So with a stock alt 70 amps is the threshold. If your total draw is less than that your charging the battery if it needs it, if your total draw is more than that then your draining your battery until it runs out. Unless your going to slap like 6 100watt rally lights on the car and try powering 4 15" subs pumping out a few 1000 watts the stock charging system should do just fine.
I have 2 800w (max) 500rms amps in my celica...and a bunch of random electronics....and it has no problems running them....
just make sure you use proper sized wire for teh amp and that the battery is grounded to the chassis nicely and youll be ok
awesome. thanks guys! this helped a bunch. now i need to learn how to solder so that i do not have 3 connectors running off the positive terminal. hahaha
learn how to solder? you probably know how you've just never tried it's very easy.....just look up a video on youtube instead of having me explain it haha
A power distribution block is nice to have too. Just pick the one that corresponds to the wire gauge you're using, preferably one with fuses. http://www.scosche.com/products/sfID1/1 ... /sfID3/254 -K
o0o0o that is way better than what i thought i was going to have to do. oh man. not solder to the battery but making the positive wires all one connection and not having 3 there on the terminal. i be silly as hell!
I believe the one I have is PDM48X2I, just with (yellow) 20 amp fuses. Sorry, I can't seem to find the watts > fuse size chart I have, but I found some other goodies. Here's some good reads on crutchfield, the formula to determine your watts > amperes total if you really want to know how much your pushing your alt. ..."To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 300 watts RMS per channel would be 600 watts). Double it to account for amplifier inefficiency (600 watts X 2 = 1200 watts), then divide by the average output Voltage of an alternator, 13.8 volts (1200 divided by 13.8 = 87 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (87 amps divided by 3 = 29 amps). The result is the amplifier's approximate average current draw...."
