Hey I have a Peavey 35 Watt, 16.7v RMS 8 OHMS guitar amp I have been useing for my bass (actualy sounds pretty good. lol Recently one of my roomates kids ramed something in the pack and tore the speaker to hell so I need to replace it. I have been thinking I have a 12 inch sub the same size as the speaker that is in there. Is there a difference? Can I just put it in there? Thanks for the help in advance. Play on brothers.
