I have alot of electronic devices in my car that require power.
I have a 2000w amp and a cap hooked up that is powering 2 audiobahn 1000w subs, i have underbody neons, 4 under the seat neons, playstation 2 in the trunk, and a 7 inch video monitor on my dashboard that is hooked up to a cap, and im planning on getting 2 sun visor monitors and a nonskip dvd player.
i was wondering if i should hook up a second battery in my trunk, if so how would i go about doing this. Anyone that can help thanks.
I would also check into upgrading your altenator. A DEEP CYCLE battery is what you will need for your second battery install what this simply does is allow you to run your system(s) when the car is off until the battery is dead still allowing you to start your car and recharge the primary starting battery this wont take care of your main power issues from expeirence i would recomnd installing the components see how your car can handel the load and then considering upgrading alternator and or battery>
105 Will definalty not be enough, so go ahead and upgrade your altenator to a 140 amp, that should house all the power you need, take a little bit of your batteries current load. Hope your Stereo system is a succes, Jason Have fun Dread07,
Dread, Will 140 be ok for 3 amps? I'm gettin another JL 500.1 after i get my new alt. Wanna make sure 140 will hold (2) jl 500.1 and an Eclipse 32440. (about 490w max)
the 32440 is 80w x 4, so 329 watts, class AB. that draws about 38A at full output the two 500/1 amps combined will draw 100A. that's about 140A total for the audio system. Your car already has a 105A alternator stock, most of which is probably used by the car, as I assume you have power everything with an alternator that large.
For full output from the system, you'll want a 250A alternator ideally, or 200A minimum. Beyond that, ideally, you'll also want around 3 to 5 farads of capacitance for peak draw moments from the system. The alternator is sufficient for the continuous draw at 200-250A. The capacitance would handle very brief moments of larger draws, as well as increase transient response time from the amps. Note for 140A of current you'll need at least 2AWG cable from battery to distro block, then 4AWG to each 500/1 and 8AWG or 4AWG to the 32440 4AWG for ground as well.
the alternator is the source for electrical current in the car when the engine is running. this supplies current to your car's computers, spark plugs, head lights, radio, and anything else that uses electrical current.
