Hi Polkies I'm back, havent been on for a long while. I recently sold my buddy my DB 5.25" for his neon and he installed to them to his sucky-ass Sony XPlod deck. He hates the deck but can't afford better right this min. He had a nice ass HTC Desire to trade for the Polks so I couldn't pass that up :) Anyways...as far as sound tuning possibilities on the XPlod all he has is HPF (80,100,120,140,160) LPF (80,100,120,140,160 Rev and Norm) Low,Mid,Hi Loudness and Preset EQs. He's saving up as much as can to get him a nice deck and some amps. He's a total newbie but knows beyond a reasonable doubt he loves those Polks. I think the next thing he's gettin is the db 6x9s. I'm tryin to help him tune his components the best I can and kinda need a starting point. His deck can go to 50 and I told him that he wants his filters at 80hz, loudness off, and negative his low,mid,hi. He's got the tweet on the xover at -3. What can y'all suggest from here?
