I was looking for a modest improvement, mostly in the lower range which is the worse part of the hi-fi system IMO. I wanted a little more punch from the underseats and the JL600/6 budget solution gave me just that (with a Technic harness). I went that route since almost everyone agree that the amp is the first weak link to upgrade. From there, if you think you want more power/clarity, you have enough power to drive aftermarket speakers.

Fast forward to today, if I were to do it again, I would consider the Helix DSP before the JL600/6 for flexibility, but it could lack power if you are to add speakers down the road.

Next step is adding MBQuart kit, but I'm not sure if the improvement would be worth it...or if I really need it

Hi Rick,
So just changing your amp first substantially bright to life the rest of your hifi system ? I also have a hifi in my 2011- would you recommend te JL600 amp still?
Any functionality loss going with this amp ? How was the install (trunk?)
Looks like ctuna summed it up pretty much! Thanks to him, a very knowledgeable guy in the audio section.

Herakles, JL600/6 is the perfect drop-in for a DIYer on a budget looking to boost the bass and a little more clarity. But on OEM speakers, one can only hope for so much improvement... No downside IMO, all functionnality are retained.

Good luck
