Finally finished getting both of the JL XD Audio XD amps installed.
I already had the JL Audio XD600/1 and the JL Stealthbox sub box installed.
I just installed the JL Audio XD400/4 to power the four Infinity door speakers.
The new JL Audio XD amps have a very small footprint and lots of clean power.
What a huge difference!!! Crisp, full and a lot more clarity in the mids and highs.
The only way I know how to describe it is...it now has a much better "balance".
Here are a couple of pics of the finished install.
Door closes with room to spare
