Here is what I have so far: HU: Pioneer FH-X731BT - [URL="http://www.crutchfield.com/p_130X731...FH-X731BT.html"]http://www.crutchfield.com/p_130X731...FH-X731BT.html[/URL] Front Speakers: Image Dynamics CTX65CS - 6.5" - [URL="http://www.woofersetc.com/p-6201-ctx65cs-image-dynamics-65-component-speaker-system.html"]CTX65CS - Image Dynamics 6.5" Component Speaker System[/URL] Precision Power BA1600.4 specs (4 channel amp) RMS Power Rating: 4 ohms: 130 watts x 4 chan. 2 ohms: 200 watts x 4 chan. Bridged, 4 ohms: 400 watts x 2 chan. I plan to buy 1 or 2 JBL GT5s 12" for a DIY sealed box - 1ft^3 each. I want to run them off 2 channels bridged on the PPI amp - 400W RMS @ 4ohm. Each sub is rated for 275W RMS. If I run 1 JBL it would have lots of headroom. If I run 2 it would only have 72% of maximum power. Is 72% enough? Would you recommend 1 or 2? [/QUOTE]
