Amplifer and alternator question........

Im looking at a new speaker system. I want the 3-way JBLs, with a boston acoustics amp. The amp is 720RMS. I have heard that a system that is 1000RMS, you should replace the alternator, etc. Should the 720RMS be something to worry about? What about down the road, 3-5 yrs from now? thanks brian.

i dont see any reason why would installing an amplifier damage your alternator since it connects directly to the battery. Probably you just have to change the battery. I think this is where the power stabilizer comes in :P http://shop.microimageonline.com/NRG...r-EPAC-300.htm i think i think i think lol... need an expert opinion i just made this with what i have read :P its something rather than nothing right hihihi...

Since its only the speakers, you shouldn't be worried since it's a lighter load than powering a subwoofer. If the amp you're using has that much power, it should have its own power stabilizer built in, and be able to distribute power evenly through all speakers to protect from overpowering them and drawing too much power from the battery.

If you were running a subwoofer/subwoofers, getting a deep cycle battery would be recommended. Your Versa is an 09, your battery and alternator are still good lol. Until you notice any power lag or dimming headlights, its a sign that the battery can't keep up and the alternator can't charge as constant as it could. But that's depending on usage and over time. Until then, run that battery and alternator down lol.

Power stabilizer = waste of money. May as well spend the money on a deep cycle for more power and than to stabilize it lol.

well it is a five channel amp. With the 4 speakers and a sub. the speakers are getting 50w RMS each, but the sub wont be for about 2 months after I get the set up. I still have to choose what kind of sub I want/need. It said the 5ch amp uses 250 RMS. Im getting the 3 way JBL's, and Im not sure if they will supply enough bass, so thats why im looking into a 5ch amp, and a sub. I dont want 2 amps. I dont need anything to rattle windows. I just want a nice sound system. So I figured the speakers wont provide enough bass. I just wont be getting the sub right away.

Just a heads up but apologize for reviving up this thread. Just wanna share. Im actualy using the 4 boss speakers powered by a 400 watt but the amp is hidden on the chairs and it's pretty working. It gives it just enough power to make it sound good while not blowing my eardrums from bass.
