Subs in the trunk?
 

I'm actually a major producer of electronic music and I just bought a great '88 'lude (w00t)! And subs would be cool, but they go in the trunk?! I mean if they do I'm down with that but, uh, wouldn't your back seat eat up all the sound? I know I sound like a noob but I've actually never been in a car with subs, I've only heard them from a distance. I guess that would be the ideal place, but wouldn't it sound better if it were possible to mount the subs inside the interior? I know that would kill the backseat cruiser but ... ok I'm babbling ...

They go in the trunk??

Yes, in the trunk.. Depending on on how well the intererior of your car is sound/weather-proofed, the bass can be heard from inside..

ex:
1- 92 sentra coupe (1 10" 300w rms)
2- 2002 Accord coupe (2 12" 600w rms)
Both system have very good installs. With the seats, the sentra's interior is getting more bass (even though it only has 1/2 the power).. But with the seates down/off, the Accord obviously buries the sentra..

In your case, the sound/weather-proofing wont do that much dammage.. So even with your seats up, you'll be getting a lot of whats being played.
