Iv got a older 8 ohm 10" rockford fosgate rfp-1810 with 88 db sensitivity. I wanted to run it with a 8 ohm peavy 15" 1505 with 97.9 db sensitivity in parallel in different sealed sub-woofer box's until I saw the difference in sensitivity.
How much louder would the peavy be? And since I could place it further away in my ford E350 (all the way in back) would the 10" RF woofer always be overpowered by the 15" even if I placed it closer just behind the rear seats? Another option would be my second peavy 1505, but I don't have two fosgate 10" speakers.
