Has anyone who has put two amps in their tC had any electrical problems? Must you always install a capicator when doing this? I have one 600 watt and getting ready to put in a 400 watt. While I don't think that'd be a problem, I wanted to check with the experts on here first.

Thanks.

 

i have a 1200 watt and a 400 watt and i'm fine. i'm going to upgrade to a 2nd and 3rd battery when i put my other 1200 watt one in.

don't buy a cap they're useless and a waste of money

 

get a bigger alt and a better battery.

 

Your car charges only a certain amount. Adding a Cap. will only help out a very small amount. You need to upgrade the charging system first. You can run all these amps but over time the small 70-80 amp alternator is gonna shut down and your will have other problems.....

lol adding batteries only helps when the car is off

 

exactly and since i do all car shows i need more time when the car is off.

if you wanna see my car i'm in columbia mo this weekend with my parents. you might see me around.

 

let me try and reiterate what i said about caps.

The basic principles of capacitors stay the same no matter what the use. They store a charge so that when power is needed, then disccharge. The best example is a camera. The batteries in your camera charge the capacitors so that when you push a button a bright flash of light happens and your picture is taken. This is a huge drain on your battery supply. Take it from someone that uses the hell out of a digital camera. In car audio the same thing applies. Your car battery supplies power to your capacitor and when the bass hits (camera flashing) the cap discharges. In a camera the cap has time and supply to re-charge itself because the draw on the cap is not continuous. In car audio, the draw is almos always continuous. This means that the capacitor is being drawn on just as fast as the battery can charge it. This makes the cap usless as far as providing power. There are times that a cap is usefull. This depends on how frequent the large draws on your amp are applied. The cap discharges a lot faster than your battery can so if you music causes your cap to discharge very infrequently then your bat may be able to keep up. If not then your bat will continuously be trying to charge a cap that is being discharged over and over again. I recommend multiple batteries and if necessary, an alt upgrade. For small systems, say less than 1000 watts and one that listens to mostly countrry or jazz, then a cap may be a good upgrade. If more is demanded then electical upgrades must be made, ie alternator, big 3, etc...

 

So, where's a good place to buy an upgraded alternator? I'd gladly look into that.

 

i've got a cap and an optima yellow top. im running 2 amps with about the same current draw on a 70 amp alternator and ive never had issues. the deep cycle properties of the yellow top combined with the caps power storage should help pick up the slack when the alternator is maxed out.

 

zebman the only place i know that does it is irragi but they're like 700 bucks for a 250 amp

You shouldn't have any problems running two amps in your car. I've got two and i have the factory battery and no cap and i haven't had any problems.

 

thanks for the replies, guys. the other amp is for the speakers in the car. it sounds find now running off the stereo's power, so if i had to go the route of upgrading to a more powerful alternator, then forget it. a little better sounding music isn't worth that. but from what some of you say, what im running probably shouldn't be a deal breaker. i guess the only thing to do is try and see.

thanks again.

 

A deep cycle discharges slower than the stock battery, and a cap only puts strain on the alternator. I'm surprised you're not experiencing problems.

 

you want a deep cycle to discharge slower. it will take longer for your battery to die. at the same time it will also take longer for it to charge.

 

My logic tells me that the voltage will drop furthur than normal because of the batteries resistance. I equate a yellow top to a reliable battery for normal car activities, not heart-pounding audio systems. I however, will be investing in a Kinetik audio battery down the road.

 

okay, while everybody here is argueing about ho useful capacitors are, i'm just going to suggest getting an nst 20% overdrive alternator pully. this will turn your alternator faster to generate more power for your car.

 

hmm..... im running 2 HIFONICS BRUTAS AND TITAN amp and i ahve a cap and everything seems to be runing fine

 

Your alternator only puts out 70 amps no matter if you have a lightweight pulley

 

the NST isnt a lightweight one, its a 20% over drive which means at idle you will be making more power, and charge the battery faster. Im going to be getting that when I get my S/C pulley

 

not true. the electrical components can only put out 70 amps no matter what resistance its on.
