Old Post... I know...
1. Steelcraft stinks! Everything I bought from them rusted out for my KK. Side Rails Rusted from the inside out, bull bar rusted everywhere. Second set of side rails rusted from the inside out, all brackets for everything rusted. FYI Florida and I keep my car clean.
2. Those siren speakers are going to damage your cooling system and engine components. With the restriction in airflow you are affecting your AC Condenser, Transmission Cooler and Engine radiator. Overall your engine is going to run substantially hotter and the components under the hood are going to get damaged quicker. your blocking a lot of airflow across the radiator and the ac/transmission cooler.
I did the same thing, however with these speakers below. The heat was substantially more in the engine bay and I had a lot of heat related damage in the 6 months I had those mounted. I am thinking about removing the front bumper and putting them on the tow hook area and possibly relocating the power steering cooler.
