Q-Customs Factory-fit Subwoofer Enclosures
2008 Ford F-150
The box itself is good, but the fit under the back seat of my Harley Davidson edition truck is a little tight. I had to jump on the seat to lock it. The sound of this box is 100% better than my old Pioneer vented box. Now for the reason I gave it four stars. The instructions are a little vague, if you have never installed poli inside a sub box, like me, than you are lost. I could see inside the box what it looked like double sided tape, but after 30 minutes of trying I gave up and sprayed glue inside the box. The connectors they enclose, are too small to connect to the box inside terminals, lucky I had some bigger connectors around.
Pros: Great sound, paired with an Infinity sub.
Cons: Need better instructions from Q-logic. I would suggest to leave the double sided tape out and let the users install it. Pre-install the speaker wire to the sub box terminal or enclose the correct terminals. I still don't know what is the purpose of the thicker double sided tape.
