I most likely will upgrade the amplifier, it's a good amp but it's a budget subwoofer amplifier for sure.

My mid bass improved also. Crazy I thought I wired everything well the first time. I actually used my new crimper and heat shrink and helps. Never going cheap again on another build.

Well after all the input from you guys the problem has been resolved. I cleaned up all wires,connections and re-tuned the subwoofer amplifier @38v and I can now play all the way up to my clean volume level with no distortion or smells. Also the system as a whole feels alot more powerful and very clean. Btw the voltage drop is only @ .5v now after re doing all power wires and connections. I would like to thank all who helped me on this issue . I really appreciate it.

I was also thinking that aswell it has about 4-6 hrs of play time.

All EQ settings are flat 100% I use focal component 6.5s in the front and rear on crossovers

The HU is a stock unit Harmon kardon And I did adjust the line out converters. I did use a 40hz tone I was just making sure this is the way to do it.

Another question is should I use a 40hz tone to set the gain?

My volume goes up to 40 I only go to 34-35 which is clean for my head unit. And yes it was completely flat. Do you think I should recalculate the voltage setting for around 1500 watts? For the zvx 15 which is RMS for this sub?

So should I set the gain by ear or use a MM?

Also just put ofc 8 gauge on sub and to amp

Some connections were so so. Definitely wont hurt it only can help

I just re wired all connections and upgraded wires voltage drop was about 13.4v from 14.5

As far as clipping yes I was clipping pretty good but I set the gains after and it was alot better. But I know I'm still getting a little clipping still. I was not sure if the clipping could be anything else other then the amplifier.

So I will reset my gain on the amplifier and try again Thank you for the input.
