Spl Subwoofer
Best Spl subwoofer?
i wanna go with one Fi btl... but i dont wanna pay a whole bunch more upgrading my eletrical units.... how douse it really cost to upgrade eletrical... another question.. What is the best Spl Sub at 1500-1700 watts not looking to pay over 400
When your running 1500-1700w rms you are going to need an electrical upgrade. There is no way around it. I'll show you what I mean.....
If you wanted to run 1500w rms for example. If you take the 1500w and divide it by 0.8. That represents an 80% efficient amplifier which is usually what a Class D amp is. 1500w/0.8 = 1875w. That means in order to get 1500w to your sub you will need to input 1875w to the amp. 1875w / 14.4V (the running voltage of the car) = 130A. That means you will need 130A to achieve 1500w of power to your sub. Most car alternators are going to be around 70A or so. Some large trucks may have a 120A alternator. But that is still not enough power to run your system. The 130A is just to run your system and doesn't include what your car's electrical system will need. You may need an alternator around 200A to get 1500w out of your sub. That also doesn't even include the fact that your car is probably not even running at 14.4V but even less then that. That means your system will need even more current.
What you will also need to supply the power is a good battery. A deep cycle battery will be ideal because they can be fully discharged much better then a regular car battery. This is good for the quick bursts of bass when the current demand is too high for your alternator to supply. One other upgrade that will be a must if you upgrade your alternator is a big 3 upgrade. This just consists of replacing 3 wires with wires of a higher gauge.
Now I'm not trying to be discouraging and telling you all this bad news but I'm just trying to let you know the truth. If you really want to have a lot of power in your car it is going to take a lot of power to supply it. This is where a lot of upgrading is neccessary. Without a proper electrical system there is no point in spending hundreds of dollars on a sub that can take a lot of power. If you can't supply it then it is just a waste of money.
Good Luck!!!
P.S. - Don't waste your money on a cap.
