Classic Inustries subwoofer panel

[streetk14]

I was looking through the classic industries camaro catalog and saw a 1st gen camaro subwoofer package. It mounts against the rear seat from inside the trunk. It has 2 8" subs and a 200 watt amp. I'm not sure what brand/quality the comonents are. The speakers are not enclosed, and from the picture I can't tell if they fire toward the rear of the car, or the interior. It is in their 2005 catalog, but I couldn't find a picture online to post. I just wanted some opinions from you stereo guys on how you think they would sound. I'm looking to add some more bass to my system. I have a 50w x4 kenwood deck with 2 6.5"s in the kick panels and 2 6x9's in the rear shelf right now. It sounds good enough, but you really can't hear any bass over the sound of the exhaust. I have a fuel cell in the trunk right now, so fitting a box in the trunk is a problem.
