I like that space behind the seats for an Amp-Rack, but I dunno about a sub, it just seems like its only vibrating the back of your seat and is baffling the sound waves...
For instance, I have 2 Kicker S10L7's in my trunk in a Zenclosures Upfire box between the rear bar and strut domes. It was more of I had 2 subs from my previous vehicle, might as well use both instead of 1 and a paperweight more than the car
Needing that much bass.
As for the hating on Kicker, not sure why, these things sound
amazing and I've never really even turned them up. (Not that there is much need to in this tiny space)
Right now the limiting factor is the stock fronts. I plan on upgrading them to a kicker component set, but my problem right now is I do plan on "one day" gutting the interior and removing everything unessential to make it full up race car. However I have no idea when that "one day" will be. So to get them and go through the trouble of installing them right now, and enjoying them until that day, or not bothering since eventually they'll be removed.
If anyone knows of someone looking to sell a Single 10" Square hole upfire Zenclosures box, I would be really interested in that sale/trade.
