The main goal for my civic is to keep it as factory(or looking as factory) as possible, retain full functionality and an upgrade or two for modern comforts. I bought the car for $300 with a hole in the block, a flat tire and shredded speakers. Motor fixed, new tires and components from Alpine to the rescue.....even kept the factory '94 radio!(Thanks to the SoundByte) Now I want a sub to supplement the low(very low) range that the components just cant hit.

I want to keep ALL of my trunk space, so I was thinking of a cabin mounted sub. It has to look factory though. So after some searching I found this:Stealth Subwoofer Install Meets my criteria perfectly. Any of you audio gurus attempt this before?
