I need to buy one of these, and i want to go as big as possible, what sizes fir in a '04 coupe, anyone using one of these?

 

Never heard of one. Care to educate me?

 

yeah sure man, they are like the best batteries when it comes to car audio. The biggest selling point to these is how fast they recharge. Most people will go with what they prefer of course, but i destroyed my yellow top and this will replace it. check out the link below for technical specifics.

Best bet would be to call any of their authorized dealers for size info.

I would stick with the yellotop. Never heard of Kinetics. At first I thought it was the "Kinetic" brand that manufactures G35 parts from their garage. lol

 

I use one and it is amazing! I can check the size for you when I get back home. PM me so I dont forget

 

oh dude, i bought the HC1800 and made some custom mounting brakets.....this battery is absoleutely amazing!!!!

 

from what i hear, they are better than optima's....
