I'm going to buy a 4" pvc coupling, glue extra pvc inside to double the wall thickness so it will accept screws, then paint it black and I should have a pretty nice sounding system.I'm curious if anyones made a box with multiple speakers inside before?I know I shouldn't need a port for speakers this small, but would I be better off seperating them and using two end caps to make a pod for each speaker instead of one coupling holding both speakers?

For this application I don't think there is any need for stereo separation. You're going to run into cancellation issues if separated, and if kept in one enclosure you can wire them in series to provide a lower draw on the amp.

Thanks alot, i guess for how much pvc costs i should just buy a few fittings to experiment with, they might sound alot better in a 90* then they would in a small coupling.Its alright to wire 4ohm speakers in series with a 4 ohm amp?I haven't messed with car audio for awhile and for some reason I was thinking I need 2 ohm speakers to run in a series with a 4 ohm amp.

You'll end up with an 8 ohm load, which will be fine.

Now I just need to make my speaker boxes.It sounds great though even without the boxes.If I turn the amp's power/gain as low as it gets, then just use the volume on my phone to control the amp it will suprisingly get fairly loud and I listened to it with the volume low for about a hour now without my battery losing any power.With the amps power turned down I should be able to listen to music for 2-3 hours at least before I need to start the bike.But the amp has more then enough power for those Kickers, once I turn the amps power up to 1/3 the speakers start bumping like crazy and the volt meter dips down from 12.7 to 12.0 instantly when the bass hits lol.I couldn't be happier with both the speakers and amp, the amp is crazy small for how loud it gets.

Looks like it will turn out to be a nice project. You don't need to worry too much about sealing the boxes fully, but that will help with bass response to a degree.
