I’m impressed at the build quality and the tone this box makes with my 4 ampere audio subs in it! I have had different models of subs 8’s,10’s,12’s and 15’s in my vehicle and lets just say these Ampere 6.5 subs in the proper tuned enclosure make air move and the sound is out of this world ! I would suggest if you have the money or credit do it right get a box built to spec by the pro Keith Sanders you will not regret it one bit! JP doesn't lie get some of the D4S difference you will be glad you took care of you! View All Close
