I purchased an Alpine ilx-107 and PDX-V9. The HU has some light tuning options available tuning options available for it. It can set simple crossover settings and delays. In order to improve sound quality, I am thinking I am going to get AF GB15, GS690 and a JL audio sub. I would not use the back seats.

Could I set up the tunes with front outputs running to the amp and then the tweets, The rear speakers would be removed.

Would this allow the Alpine Headunit to act as a DSP setting a time alightment and cross over for each of the front speakers. Would this work or would using the same connections work better.

thanks for any inpurts
