Well first, I'd like to say hello, I just joined this forum. I just started with car audio a few years ago
Here's my current setup in my 1997 Pontiac GTP
Kenwood KDC-MP345U Headunit
Kicker L5 15" in Ported Box ( Box not much bigger than Sub)
Kicker zx750.1 Amp
2 GA Power, running off stock power sources
"Big Three" done under hood
Here are the problems: The sub doesn't seem to be hitting as hard as it should. I have bass-boost on amp all the way down, gain on 8/11, and headunit bass flat. It doesn't hit fairly low notes, e.x. it sounds to be struggling to hit the notes in "Burn Rubber" by Too Short, and doesn't hit fairly high notes for this kind of sub, e.x. it half ass's the higher notes in "Top Back" by T.I. (not trying to tune my subs to songs, just trying to give easy examples)
Here's what i think it is personally, the frequency nob moves, but doesn't seem to change anything sound-wise. Is this because there is a problem with the amp, or is it my headunit with the "Pass Thru option selected"?
Also, my ground wire is a very cheap quality ebay 0 GA clipped to 2 GA. The wire strands seem thinner than the one's from my speaker wire.
To add to note, The sub doesn't really flex at all tbh, although it hits, it does flex. When I had my older oldschool bd1000.1 amp, it flexed/hit hard, but amp overheated.
Any tip, suggestions, or solutions? Thanks in advance. Great forum to be part of.
