Connectors for big 3 and amp supply

[Brian617]

These 2 way connectors look pretty neat:

I was thinking leave the auto wiring on the side of the battery and use the top posts for the stereo. The negative post would have one run to the alternator case side of the bracket, and the other to the strut tower. The positive post would have one run to the alternator positive post, and one to the amps in the back (around 2k watts total). My thoughts that could cause concern would be:

- One chassis ground point instead of two for alternator and battery

- Compression terminals instead of soldered lugs

But it seems that with the capacity of 2/0 wire and connectors, for only 2000 watts that setup would be more than adequate. Am I wrong?
