car amp

So to start off I have a basic knowledge of the car audio stuff. I installed these subs and my door speakers by myself. I have two brand new kicker comp vrs they are 10 inch subs powered by an infinity kappa k600 so 600Watts. Before I got these brand new subs I had two kicker comp s’s in my car...

Hey i'm about to be running a 2200w amp in my car and don't know what kind/farad capacitor I need so I don't have my headlights dim and so that I have ample power supply. If there is anything else I would need or that would help me. Anything would be appreciated.

So I found a cheap powersupply that I wanted to buy the EVGA GQ 750W but I don't understand what, GQ,G2,G3,G1 means.

Like the question asks, can I have an R9 290 video card on a AMD 760G Chipset motherboard? The computer I'm buying is a CyberpowerPC Gamer Ultra GUA880 Desktop and it comes with the AMD 760G Chipset. I'm also purchasing a 650 watt PSU because the 500 watt that comes with it is not enough.
