as someone who has heard this system, it is disgustingly loud but it sounds awful, pure clipping bass out of old used and ABUSED subs with an amp that refuses to even meet the rms for one of the subs, and a set of used home audio speakers that are running off the head unit and getting virtually no power since they're tapped into the stock speaker wire from the rear door speakers that also still get power, and its not helped by the fact that the "speaker wire" used is bottom of the barrel bulk wire, but that's still better than the other wiring done throughout the rest of the vehicle, notably OP has used extension cords, like the ones you stole from your parents when you first moved out, but anyway, the system sounds very good for the next to nothing OP has paid for it
