I recently acquired these speakers and crossovers for my truck. I know a little about audio stuff but nothing to major, so i was hoping somebody could shed some light. Are these things worth anything? are they worth going through the hassle of putting them in my truck? Or should i just stick them in a box somewhere and leave them.

 

Old school MB Quart is good stuff. In the 90's, these were their mid quality/price line. You really don't need both sets. Sell one set (or box them to use as backups in case something fails) and put one set in the front (going to take some mods... mdf adapter rings and cutting the back of the door card).

If you want to get the most out of them, seal and deaden the doors, get a 4 channel amp, and run 16 ga wire to them. Those are bi-amp crossovers so each crossover will take two channels. You can use a 2 channel amp and bridge the crossover but it's best to drive them with a 4 channel amp and set it to bandpass.
