So a little background on my system. Im running stock radio , alpine mrp850(800watt@ 2ohm)10"rockford t1,rockford p162s speakers(running off stock radio for now), monster cables.should be a 1200 watt system when done

Im not sure how common this is or what needs to be upgraded but maybe some of the audio guys can point me in the right direction. I never worked under the hood with my system on loud and engine running but today i did and noticed how much my system is draining power from my engine. Everytime the bass drops my engine will pull.
Also my lights dim due to the system so i knew an upgrade of some sort was needed allready.

So im thinking i need to upgrade the big three and a new battery maybe yellow top? (id prefer somthing less weight). What about a starter do you think i need more amps? maybe 180? I think the hr comes 150 stock...i know nothing on alfernators what brands are good?

 

simple fix is add a cap! the cap will help when the bass hits it draws from the cap not the battery. the stock LiOn battery is way better than the yellow top. and if you add another amp i defetanly sugest a larger altinator, they cost about $500. dont buy a cheep fleabay one all they do is swap the pully and it will burn out fast.

When and if you do an amplifier you need to also make sure your Ground cable is matching your Power cable.
