View Full Version : 04 Silverado Ext cab underseat box plans?

Well, I am ordering a pair of Inifinity Kappa Perfect 12DVQ.. the specs are listed below..

Power Handling, RMS: 400 Watts
Power Handling, Peak: 1600 Watts
Frequency Response (3dB): 25Hz - 400Hz
Mounting Depth: 7"
Impedance: 2 or 8 Ohms depending on wiring
Sensitivity: 92dB

I am hoping to be able to fit these under my rear seats without any modification, but if any needed I would prefer not much more than a seat lift.

Does anyone have any sealed box designs that can accomidate these subs in my truck?

ya man that **** wont be a problem. I have 2 mtx 12's under mine (04 sierra ext cab).
You can do it easily by making some 2 inch blocks for the rear seat.

I have have a final tomorrow morning, but in the aft i'll get you the measurements of the box i built... might be able to get ya some pics too.
if you want just pm me, cuz i'll probably forget
