Probably but it was two separate outputs of the stock amp so using one would be 4 ohms "metered it and confirmed it" so the kicker went in no problems.
Went to install his fronts today and he got bent out of shape because. I told him first I have to run a new wire through the door for the tweeter from the new crossover. "After telling him that 2 weeks ago" I will honestly say I broke a small side cover above the door "first in a while for me" offered to replace it but he said na. Than he bought a bulk pack of dynamat and got so mad at that he yelled I am not putting any of this crap in continue. Than when he asked how the tweeters would be put in I told him using the mounting cups and maybe a bit of epoxy or some bondo, he said nope pack it all up were done.
Apparently he does not like any kind of glue neer his car or in his car. So no new components went it nor do I think they will. I feel bad and will buy him a new piece but I think the install is done.
