I have a US car, and when I did an audio install this weekend I was a bit surprised how small the battery was. I suppose in most of the US you are not too worried about cold cranking amps... but even with the demands of a subwoofer amp, I wonder if this little battery will manage. On top of that -20 is not unheard of in the winter here. I am running a 600w RMS amp do you think I should get a higher capacity battery?

 

my new battery has a capacity of 1.21 Gigawatts

 

So... is this a replacement battery or the one that came in your G? I am assuming that you have a Canadian car...

 

lol, i'm teasing you, 1.21 giggawatts is nuts. that's "Back to the Future" crazy


and yea, I got a CDN G

 

Should have known... I have never seen a battery rated in watts before... and Giga is 10E9 which is huge. Anyway... have you looked at your battery under the lovely plastic cover? Mine is a lot smaller than the tray that it sits in... and while it may be OK for southern climates... I am a bit dubious about it up here.

 

Probably wouldn't hurt to put an Optima in there.

 

mines regular size, it's just like Black betty's pics in the grounding wire thread


definitely not, it wouldnt hurt

 

i apparently killed my factory battery by using the seat warmer once...

it was fine until the day i used it then it died. dealer replaced for free

haha and i dont have any aftermarket audio equipment either. not yet anyways still working on it

 

I don't imagine that the seat warmer is light drain, but it would be nothing like a 600W amp that will pull in the vicinity of 50 amps on full load. I guess that I will be dropping in a big battery before winter...

You'll need more than 2 Optima's for just one of these.

 

There is a brand marketed up here called "yellow tops"...often used in extreme audio applications... I wonder if it is similar to the battery you describe.

 

Yellow tops are Optima's but there are many similar batteries. I used to run two 12" W6s on a 1400.1 with the stock battery. It lasted over 3 years and is still going. I do live in South Florida so it was only below 50 two days a year. You can see the light dimming slightly especially when you first begin driving but as long as you're not consistently driving 2-3 and turning off the car, it will stay charged. Maybe invest in a cap, I'm sure the battery can handle cold whether and even though the AMP is 600W unless you have a W7 or something comparable, it not using more than 300, or so.

 

Thanks for the info DiamondG... I am running an Alpine Type R (500w RMS), which is not in the same league as the W7 but probably close to the W6. I don't know much about JL so my comparison may be off, but my guess is that the W7 is similar to the Alpine type X (1000w).

Still, even with the type R, I can feel my hair move and all the mirrors are vibrating I am pretty happy with it especially considering the small, non ported enclosure.
