That in fact, is the amp for your speakers. Depending on what system you have, it is most likely the amplifier for all if the tweeters in the vehicle. It's a 4 channel amp. There are 2 amps under the back 'dash' each of which are 2 channel. The one on the passenger side is for the front and rear mids on the passenger side and the one on the drivers side is for the front and rear mids on the drivers side.
