Theres plenty of people here that will help you with this, my only advice is to thuroughly explain what you want. Pictures help a lot, and diagrams too! Just make sure u fully explain what you want, what equipment you are using, and your experience. This is a great site to get any info about upgrades and modifications for your Pat.

Your high/low convertor is what makes your system sound bad. A single 10" sub and amp, even if they are very low quality, should give you enough bass and not sound bad at all. I hate high/low converters. I bite the bullet and bought the adapter from PAC for $44. From my experience, it was worth the money. My system sounds great.
