Well for daily I used mine on 2 12 AW1208Ts @ 2 ohm really loud but nice never had them on anything else or a setup that large but I would say in a f150 you would be loud as hell.
Refs you have to use my ebay name Joe456654, Specs are 2000 rms at 2 ohm and 4600 rms at 1 ohm stable at 0.5 ohm but not sure of power prob somewhere between 5500 and 6500 rms.
You know you want it 600.00 plus shipping OBO
