I didn't read everything [I just looked at the pics ] and you probably already know this, but make sure your amp has ventillation to take away the heat .. Looks GOOD !

Looks great, where was the stock amp located or is there even a stock amp? I plan on hooking my amp up to the Performance Sound switch, so I will come back for info, when I get ready to do it.




I honestly don't know where the stock amp goes, there is a slot in the plastic panel by the center hump that may hold it. I only bought the stock housing and performance sound overhead piece, decided to use an aftermarket amp. Hooking up the overhead piece will be a bit of a trick, I haven't looked at it in detail yet. I'm planning on making it control the high-level inputs, basically controlling the volume of what is going into the amp.

I will be making sure the amp can ventilate, whats nice is with this sub I have the gain on 0 and still provide plenty of bass, a continuous hour of use produced very little heat.

You can't really see it in the pic, but part of the reason I installed the amp sideways is now the heatsinks are on the left and right, running up and down. This way air will naturally be drawn in the bottom and vent out the top. When the rear panel is finished there will be mesh to allow heat out and cooler air in.

Cool I plan on seeing how you hook it up, so I can do the same.

The basic rule is to stuff sealed boxes and line ported boxes. The stock subwoofer enclosure is ported. So you don't want to completely fill it. But it wouldn't hurt to line the inside walls. If you do use stuffing, make sure the air can flow freely between the speaker and the port.

Just curious but isn't that amp going to over power that 5" subwoofer or are you planning on using a bigger subwoofer such as an 8" sub??

Nice setup!

Thanks for the info, I'll give it a try when I have the box out again What is a good material to use?

The amp is a bit much, I have the gain on "0" right now and it is plenty. I was actually planning to do an 8" under-dash sub like a few people here have done. I may not bother to do so now, after hearing how this one sounds, it is surprisingly powerful. One nice side-effect is the amp produces very little heat, since its barely even trying to drive this sub.

Just about anything soft and fluffy should work. Some common things to use for stuffing are pillow stuffing, cotton balls, and fiberglass insulation. (Although, I wouldn't suggest using fiberglass insulation. That stuff is evil!) Some common things to use for lining the walls are foam rubber, shaggy carpet, and blankets.

BTW, I really like your attention to detail. Keep up the good work!

Try the fabrics section at WalMart; they have batting, stuffing, and all kinds of stuff like this cheap

Hey guy's, sorry but I've got what might be a stupid question to ask so I appologize ahead of time.
My question is - does adjusting the gain on an amplifier reduce the watts RMS that is sent to the subwoofer. I've also got a similar set up to Xanth's in my car with the exception of the amplifier as I'm afraid to use my current amp which is rated at 170 watts RMS x 1 channel. If reducing the gain to minimum will reduce the RMS watts then that will save me from getting another amplifier. Can someone confirm whether adjusting the gain does anything to the RMS watts sent to the sub. I've got a sub that's rated at 50 watts RMS and I don't want to over power it and blow it up.

Thanks!

As long as the signal isn't clipped, you can run 500+ rms to any sub, and it won't blow it.
