Well I finally found some time to install the JBL P80.4 amplifier that I bought a couple weeks ago. I will give a detailed review on it in a bit, but I have a couple questions I would like answered being this is the first amp I've installed.
First starting with gains. I understand that to adjust the gains, one would start from the lowest setting and turn them up until the speakers start to distort, and turn them back down a bit. Since I am using a 4 channel amplifier, if I set the front/vocal speakers to the optimal gain setting, they will drown out the mid/bass speakers at their optimal gain setting. Is there anything wrong with setting the gains lower on the vocals to balance the system out? In other words, I know it is not good to turn the gains up to make up for lack of good speakers, but what about turning them down to obtain the proper sound level?
Ideally, how should the treble and bass be tuned on the radio? In an ideal situation, would these be set to 0 and the amplifier and speakers would simply make up for all the treble and bass needed, or would even in a completely upgraded system do people play with the treble and bass to fine tune? I'm asking because my bass/midbass stills seems lacking (need new speakers I know), and I'm wanting to turn the bass on the highest level.
Lastly, the crossovers. Ok, for the front speakers/vocals I set this to High Pass, correct. And for the midbass/bass speakers I set these to Low Pass, right? So when I set the frequecny for the midbass speakers, lets say around 100hz, then I would also set the front speakers at 100hz?
Alrighty, that is all for now. Thank you!
