I've got a 2004 x2 with the 4 in boat speaker, 2 factory tower speakers, and an Alpine type R 12. The in-boats are run off the old clarion xmd3 and the tower speakers and sub are running off of a JL M4300. I'm thinking of either getting another M4300, which will allow me to amp the in-boats or a mono sub amp to run the sub and then just amp the in-boats with the M4300 and run the tower speakers off the radio. I'm not too concerned about hearing the music while riding or anything, so I don't really care if the tower speakers are loud, so I'm leaning towards that second option.
I guess my biggest question is...I have a single optima blue top, am I gonna drain down my battery if I stop and listen to the stereo for 5 minutes? I really don't stop and sit that much, as we have a house on the lake and if I want to sit I will just go to the house.
All opinions are appreciated.
