I HAVE ALREADY INSTALLED AN ALPINE HU AND I HAVE MB QUARTZ PERFORMANCE COMPONENTS IN THE FRONT AND COAX IN THE REAR. I AM READY TO START ON A SUB BOX IN THE STOCK LOCATION YET AM HAVING A HELL OF A TIME SELECTING THE RIGHT SUB AND AMP FOR THE PROJECT. I AM LOOKING AT THE JL 10" W3V2 AND I REALLY JUST AM LOST WHEN IT COMES TO THE RIGHT AMP. I AM REALLY DEBATING BECAUSE I THINK I HAVE PLENTY OF SOUND COMING FROM MY HEAD UNIT ALREADY SO I DON'T KNOW IF I NEED TO GO BACK AND RUN A 5 CHANNEL AMP OR IF I SHOULD JUST GET A MONO AMP. i WANT TO MAKE SURE THAT MY SYSTEM SOUNDS VERY CLEAN NOT JUST LOUD. ANY SUGESTIONS ON THE LEAST EXPENSIVE SOLUTION?
