I have a 99 Acura 3.2 TL with a Napa legend 75 battery would putting a 1000 watt amp and 2 15 subs hurt my car?


Your question title doesn't quite match the body... but I'll answer both:

Simply put, this shouldn't harm your car - but that said, there are some things you may need to do:

  • Check that you have good connections to ground - a 1000W amp can draw a lot of current
  • You'll want a high current cable with inline fuse from your battery +ve to your amp. A sub being driven hard will draw more than your average car's wiring loom can cope with
  • Check the alternator is well maintained and gives a charging current of greater than the current draw of the amp :-)
  • If you plan on playing your music loud when parked with the engine off, seriously consider getting an uprated battery or maybe even a second battery. It's embarrassing how fast you can drain a battery at a beach party...
  • Thank you do you recommend any specific battery to get if I get secondary? – Santiago Ortega Sep 18 '15 at 3:47
  • Many places do "winter" or "heavy duty" batteries. I have various devices and a 650w amp in my car, and I run off a winter battery that is double the capacity of a normal battery - can't remember exact amp/hours, but that was the selling point for me – Rory Alsop Sep 18 '15 at 6:38
