How hard will it be to add all new speakers with an amp, but keep the stock headunit. I saw one member's setup with 4's & 8's in the doors, 6.5's in the rear.
Will this work? How would I power these with one 4 channel amp? I was thinking that if I ran the 4's off the HU and a 4channel to the 8's and 6'5's it would work, but i might need that $80 converter.
