Unless you are doing more than 2000 watts
You shouldn't have a problem .

Not very awake yet but

On the other hand if your are in an 07 on the original battery it
is probably time to change it.

Also never heard of that battery.

Since its AGM you will have to reprogram the car to get it to work
I think and the size is group 49/H8 . And Interstate MTP 49/H8 runs around 200 bucks or less and has a 3 year warranty.

It's the only brand I'll ever use. I had a d1200 for about 2 years and it worked good even though it is smaller than the stock size. I got a d4800 last year which is the same size as the stock battery. I've been using close to 3kw for the last 3 years I'm sure my alternator is loving that
