thanks guys! about upgrading the speakers, some of you mentioned that i should get an amp to power them so in time the HU wont blow. i dont mind getting a small amp to power them up. My question is, Im planning on having components in the front and coaxials in the rear so the coaxials will be the only ones powered by the amp or do component systems need amplification as well? Ive never dealt with component speakers, thats why i ask.
