I'm new at car audio and this is the first system I'm installing in my car. I'm hoping that some of you can answer my questions. I recently bought two Alpine Type R 10" subs and I was wondering if a MB Quart DSC 1500.1D amp will be able to power both of these subs. Also I'm looking for a good 2Din headunit that has navigation, bluetooth, usb, and dvd playback. I've been looking at a few online, but I'm lost when it comes to quality and good brands to look at. Also, are these headunit usually powerful enough to handle two Alpine Type R coaxial speakers or will I need an amp for those too? Any suggestions would be appreciated! My system I'm trying to put together is going to look something like this: Alpine Type R 10" subs (2) Alpine Type R 6x8 coaxial speaker (2) Headunit (2 Din, Navi, BT, USB, DVD Playback) This unit is going in a 2004 Mustang Mach. Any suggestions or tips you might have will be greatly appreciated. Things like amp, headunit, etc suggestions is welcome. Thanks inadvance for any help!
