Get one of the 320 Amp HO's here: <a href="https://www.qualitypowerauto.com/catalog.php?item=467" target="_blank">https://www.qualitypowerauto.com/catalog.php?item=467</a>At 3000 Watts and at 13.8VDC you're pulling about 217 amps peak. Generally with music playing your Amp won't draw this much power but it's a good starting point to understand how much electrical support the amp needs to properly function. Your car already uses 80-90% (~100 amps) of the stock alternator's output to run the car/lights/blinkers etc. If you get the 320 you'll have around 220 amps extra to feed the beast. If you want to can also get a battery to act as a load balancer but if you just give the system the power it needs from the start you'll be much better off.</blockquote>
