Appreciate it, DBLXX!
My GLA is slated to arrive in 2-3 weeks, but looking to have a higher power replacement battery ready to go, since the 1st place the car is going is to my audio installer for a week.
I plan to run about 1200 (real) watts (McIntosh 6 channel amp and ZED monoblock), which is going to push the limits on the 115 amp alternator.
