so i got the first part. now i see a few people talked about electrical. does that mean if he had the proper electrical system the 500watts would make a difference?

this is what i was thinking. he's using 4 boss 15s (don't say it it's what he got).

i building a system for my friend and i am going to sell him one of my onx1.1500. he says that he wants to go to the 2000. i don't want him to think that i am just trying to sell my amp because i don't think the 500 watts makes a diff. but i'm not sure.

sorry but i saw this and wanted to ask when is a Amp Relay / Battery Isolator needed when adding another battery?
