Re: Will I need a capacitor?
I just purchased a Sony radio, 4 infinity speakers and an Amplifier to power them up real nice. I have two brand new Interstate batteries. Its for a small 19' Angler.
Will I need a capacitor?
No , you will not need a capacitor .
Capacitors serve to store a reserve charge , effectively giving you a little extra current when a load causes voltage draw .
For the system you have , 4 speakers ( probably 5 1/4 - 6 1/2" coaxials , you did not say..) it would be money best spent elsewhere .
IF you had a dedicated seperate amp , for powering a subwoofer or 4 , then a capacitor may help .
Keep in mind that they only store a small charge ( like a reserve tank of gas ) . They can help system output , but , only if your power supply system is allready borderline or completely inadequate for the amount of load you are drawing .
Big bass requires HUGE amounts of power , but is still a transient load .
THIS is where a cap can help , storing extra charge between these transients , holding it in reserve untill it is needed and supplying the reserve when it would otherwise cause severe voltage drop and reduced output from the system .
For most any other music in a normal listening environment , they are not a noticeable asset .
Better to spend the money on the P/S system ( alternator / batteries / wiring ..) , then spend money on a band aid , IME .
Upgrade your charging , storage , and , wiring , first . THIS is where you will reap the benefits for the current system , and , have capacity to upgrade in the future .
