Hey people I'm having trouble. I have l7 10" kicker running with a old school ppi amp running about 750watt . I had the same set up in my 2008 gs350 before it got totaled. And it would hit hard. Now I have it in my 2001 ls430 and it doesn't sound the same.
Should I move up to a 12?
Run 2 10s?
Get a bigger box?
Or more powerful amp?

 

Here's a picture of the setup

 

here it is again

 

Keep in mind that the LS is the flagship, more insulation and sound deadening.
Dont forget that audio source makes a difference as well. I have run an 8" L7 in my car for a while and it hit pretty damn hard so i doubt you need to upgrade woofers.
