How much will Subwoofers Shorten the Life of my Car?

I’ve heard it said that running subwoofers in my car will shorten its lifespan and was wondering by how much. I own a 2001 Honda CR-VS with a 475 amp battery and drive it maybe 1.5 hours each day. I plan on installing a 2400 watt sub. with a 2000 watt amp, the details are as follows:

Pyramid PB779X 2000 Watt 2 Channel Bridgeable Mosfet Amplifier
* Two Channel Bridgeable Amplification
* 2×1000 Watts Total Output @ 4 Ohms 1×2000 Watts Output Bridged Mono
* Variable Gain Control/Remote Turn On/Off
* MOSEFT Pulse Modulation Power Supply
* 2 Ohm Stereo Stable

Lanzar MXBB122 Max Pro Dual 12-Inch 2400 Watt High Power Ported Subwoofer
* Two 12” High Power 4 Ohm Subwoofer Non-Press Paper Cone
* Specially Treated Black Foam Suspension
* 2.0” Kapton Voice Coil
* 2400 Watts Max Power Handling
* Dimensions: 14.5”H x 30”W x 16.4”D

Thanks for your help!

who told you that? LOL!
you might slightly decrease the lifespan of your alternator and battery but not the whole car.
