Finally getting around to getting a sound system in the Celi, and was curious how powerful the stock equalizer head unit can push speakers. i have some cheap 2.75 speakers in the front with some nicer 5.25 Skar audio speakers in the rear, with an RMS of 45w, and peak of 150. My dad has a bazooka he will be giving me too just to bump it a bit more, which ill stash behind rear sears since my cargo roll covers it nicely. Will i need to install some sort of amplifier to push them or with the OEM headunit suffice? no need for window breaking sound (mostly since windshields got nasty chips)
