Hey there. My name is Matt.
I am new to this site and car audio in general.
I was looking around and its looks like a ported box is better than a sealed box. I currently have 2 15'' MTX Thunder 4500's in a sealed box. I've had them for almost a month now and already want to improve.
Any suggestions and/or box designs that would improve my system would be greatly appreciated.
Also if it helps i drive a 05 GMC Envoy.
Thanks, Matt
