well the old system has been out of my truck for awhile now and i was using the factory radio but now have the pioneer head unit i mentioned before, and the only thing that is worth saving from the subs is actually just one sub, the amp broke, the wiring was fried and the box that the subs came is was getting torn up. After reading what you wrote Lagexe, i see how as you upgrade your system you need to change all the wires and grounds but i guess im just looking for simple bass...if thats even possible...not sure if i want to tackle changing all that stuff i my truck
