Hello, does anyone know the exact WxH specs for either the factory or kicker replacement amps? Our JK was a stock audio setup and I have gutted everything and replaced... next step is the amp and a small sub...

for security and space saving purposes, I'd like to mount the amp behind the steering wheel and just trying to find what my amp options are, based on what will fit in there.

Any help would be appreciated. I know the alpine pdx fits but the new speakers are already very loud and deep, so i was considering a small mono amp instead.

Thanks
