Subs just don't seem loud enough

Okay. Could a bad ground cause a wattage drop in the system? It's just not making any sense to me that my friends l7 12s can be heard from down the road and my two 15s sound like some cheap 10s just enough bass to over ride door speakers.

absolutely. what are you grounded to? that was my issue with my system at first.

I have the amp grounded to an existing seat bolt and I sanded off As much paint as I could. This was the only easily accessible thing to put the ring terminal onto.

seat bolts are one of the worst places you can ground. i can almost guarentee thats one of your problems.

Grobbins, are you talking about my setup, lol, BC I'm having the same exact issues and practically the same scenario.

I can't find anywhere else to ground to. What do you reccomend I do for a ground. I've considered that was my problem from the start but the fact they were merely working made me push it aside until now.

That's a lot of amp to be grounded anywhere but directly to the frame. Seat bolts in newer cars are usually oddly shaped and make horrible grounding points. Definitely change the ground and see if that helps.

ground to the actual frame of the car, or spend the extra money to do one long ground connecting straight to your battery.

how would I go about grounding straight to the frame? Run the ground out of the cab onto the frame? what kind of screw or an actual bolt? can the ground get wet ? lots of questions I know but I want to be sure. Still learning here lol

nah keep it dry. and you should use a bolt and nut. you just gotta get creative and make your own ground

Yes, I'm so disappointed, just like you, I used to have an L7 15" and sounded way louder than now after spending almost 2k upgrading my stuff.

yeah guys try relocating your grounds. sand to bare metal, make sure they are tight.
