Question:
i have 2 12" 1200watt subs, and jus bought a 2 channel 2400watt amp. and im new at this car audio thing, and well ive usef a smaller amp before, never one this big. i was wondering what is the best way to hook up the amp main power supply. should i run it stright to my main battery for my car like i did with my smaller one, or will it drain the car battery too much? or should i get a seperate battery to hook up the amp to it. also if i get the seperate battery, wont it go dead after a few weeks? how should i do this?
How do you wire two dual voice coil subs in a sealed box to a mono amp??
please help
Answers:
with all that investment get a pro to install it. If you wire something wrong you could blow an amp etc When in doubt use a pro then you know its done right.
What kind of car stereo system is inexpensive but good?
It does depend on the quality of the battery - and with your monster amp that is very important. Also the best cabling kit is required - some can be expensive - but its well worth the money. You will get better sound from better cables.What is cheaper than dynamat and has the same performance?
You will need to run the power cable straight from the battery and you will also need a 2.5- 3 farad capacitor and possibly a new heavy duty alternator and a battery. If you were to get a new battery and not charge it with the alternator It would go dead in a few hours not weeks. Even if the other battery was hooked up to the alternator it wouldn't make any more electricity becuase the alternator would still be the weak point in the system. If the amp is less than 1500 rms then you should be able to get by with a 0 guage power and ground and your stock battery and alternator, don't forget your power capacitor. After that you start sucking power away from other things. (These are estimates based on a midsized car, if you have a compact you might get 1000, or with an suv or a truck you would get alot more (I really don't know)) Good luck, wear earplugs.Congrats on your new system. You can run it a couple ways. First, you can run it to the battery like you did the smaller one. However, you will have to upgrade the altenator, and add a capacitor. You can also install a battery in the trunk, be sure to get a crash case for it. The "crash case" is like a battery roll cage. In case of a rear end collision. You really dont want somethin like that not protected that close to your fuel tank. With the battery in the trunk you can use til it dies then charge it with a jump box, or a D/C charger. You could buy a second battery and switch them out when you notice the system is gettin weak. That way one is always on charge, and ready to go. That can cause you to lose several fuses, connecting and re-connecting. I heard that you can run the second battery off the first, but it consists of seriously upgrading the altenator, or adding a second altenator. Personally, what I've done in the past was running the power to the main battery, and upping my altenator, added a capacitor and I was good to go. depending on what you drive, you might want to look for a stronger battery as well. They have batteries that have higher amps, in the same relative size.
How much does it usually cost to get lambo door put on a car?
your cars battery will be fine. If you notice that your headlights dim when bass plays, you might consider adding a capacitor. They sell for around $100. Just install using the supplied directions. And pay attention to where they say never grab both sides of the capacitor.What car speakers have the best sound quality?
Best of Luck!
i would put a secon battery in it and have a wire runing from it to help keep it charged and puttin a bigger alternator
