Capacitor, battery, or Alternator?
So I have a 2013 Honda Accord Sport with a single 12 inch sub with a kicker cxa doing 600 watts rms. This system dims my headlights. I just bought a dd712(D2) i plan on installing along side with a dd dm1500a which does 1500 watts at 1 ohm this is double the wattage from my old system so i know i have to upgrade one of the two and maybe even get a capacitor. I've called different car audio stores asking what I need to get upgraded some say i need alt. And battery uprgraded, some say I need just a battery, some say i need just an alternator. Can't figure out why i can't get just one flat answer. I don't know much about car audio but any info would be great. Here are some specs to the amp.
Cont Wattage @ 1ohm1500
Dynamic Wattage2300
Max Current Draw - Amperage230
There are a lot of them. Pick the best one.
- Which car battery is better? EverStart Maxx Lead or Duralast Gold/Battery? Facts: I drive a 2007 Honda SE, 4 cylinder. Been using a Kirkland (costco battery; group size 51r) for about 5 years. Looking for a battery in case this one dies.
- Bought a 1985 Honda inspector kid told me it needed new battery but started with jump got new battery and it was dead next day? Pretty sure its the alternator just wanted some second opinions also I got the bike for 600 dollars you guys think thats a good deal
- Car problems- is it battery or alternator or both? Car does not have enough juice to crank. Everything turns on but only clicking noise. I get a jump and it is fine for a few days. Yesterday radio starts turning off and on. Today the air conditioner (on full blast) increases power when I accelerate. Notes: 2003 Honda Civic 4 door LX 5 speed manual trans 1.7 L
- Car battery float charger goes straight to float mode though battery is dead? I recently purchased a Stanley 6v float charger because my 2 year old honda battery died pretty sure the battery was the problem since the car started fine with a jumpstart but when i took the battery out the car and plugged the charger on it, went straight to green light/charged/float mode on LED display ever seen that happen or know what's going on maybe? I'm gunna leave it plugged in over night on float mode and hope for the best
