Well, the way I understand it, is that because I am using that "high" rca output, which is individually controlled crossed/sloped and has a lowest crossover of 1000hz, that even if I hooked up an amp capable of crossing @ 500 or 1000, the HU would only send it the 1000+ "signals"??
The PE website did recomend both 500 or 1000 as a crossover, but I dont know if they will play well or not crossed at such a high freq, thats why Im in this dilemna witht his thread lol
