i think you should def go with 2 amps and 2 10" subs, you cant beat the clarity, or the thump

 

Yeah after talking to some peope i decided to amp the speakers via 4 channel, and then that should give enough power to my alpine speakers so that it will allow my head unit volume to go high without any distortions basswise .. then later on get a sub and amp

Sound good?

 

You're definitely on the right path

 

sounds like a good plan
