Hello,
I like the ideas of the speaker cable upgrade. You don't have to break the bank like a lot of people think. I’m going a different route. Try upgrading your power cable even if it’s for a surround sound receiver. Go with 12awg cable if you can but 14awg is ok too. You can start by trying some inexpensive ones on Amazon. This way if they don’t work you can return them. They will need a week or so to settle or burn in. My thinking is your basic 16awg power cable you received with your amp/ preamp or surround sound receiver is not letting your system breathe. If your amp or engine can breathe it will push your speakers more efficiently. If this works and I know it will think about upgrading to a better power cable than the one from Amazon. You can return the Amazon cables or use it on the subs which also get hungry for power. Just so you know I did this and I have all upgraded power cables to Nordost in my system. Many of the companies listed above by other members have power cables. If you live in the Chicagoland area this store lets you try before you buy. https://holmaudio.com/
That way you can really see if it works. In Nordost I would go with Red Dawn power cable. It is 14awg but really, really good.
