This is a drop-in speaker system for the PIKO Sprinter. The stock speaker sounds thin with low output. Replace this speaker with one or two of these for a fuller, smoother and louder sound. Dual speakers may be installed, one in each car facing away from one another and wired parallel for a 4Ω load. They use a little double-sided mounting-tape to secure in the seats like the stock speaker.
The speaker comes fully assembled and tested.
Dimensions: 10mmH x 15mmW x 25mmL
