Hey All. First post and haven’t done car audio in 30 years. I recently purchased a RAV4 non JBL and decided to upgrade everything but the head unit. New JBL Club dash and door speakers and a JPL sub, to go with the JBL amp. I’m using the Stadium BassHub (non powered) for my sub on the A5055 5 channel for the amp.
So I was going to set my gains on the sub output. For the input I had to split the rear signal between the rear input and the sub input. When I hook a DMM to the sub output and set head unit volume at 3/4 full volume I only get 19.2v out with gain at max!! That’s with the bass knob all the way to max on the remote. This can’t be right. This means I’m only getting about 100w @ 4 ohms. What am I doing wrong, or not seeing? Is my logic sound?
