in my jeep i went threw a 15L7 4.75cuft tuned to 28hz.. then i droped it in a sealed box 3.5cuft n felt it sounded alot better.. but i got tired of the SPL thing fast and went with Sq instead.. in the HRR right now i got my old box.. 2 16kv.2s sealed 1.66per driver... i will say the bass sounds better in this car then the cherokee but i get tons of rattleing and the rearview mirror is useless... at this point im all for sealed boxes

 

They are 2 12" pioneer premier dual 4 ohm subs rated at 1200w max per sub. I am currently running a Memphis 1100d rated at 1100w rms at 1ohm, so somewhere around 550w continuous per sub. I'm currently running off the stock head unit while i gather my money for the eclipse head unit that i want.

 

dose the stock head unit work good and do you have the optional & speaker system in your HHR?

 

I had no complaint with the stock unit until i had a system installed in our expedition and now i know i have to upgrade, the stock unit is just so limited. I have the optional system with the 6 disc changer and sub. The factory sub is still connected and operational, i been planning on disconnecting it but i'm so lazy

 

Which Eclipse are you looking at?

 

I was looking into probably picking up the avn 5435 but im leaning toward the 5500 or 6600 not positive on any one of them yet, but im researching.

 

Cool, I've got a 5495 on display that I've played with, pretty cool unit.

Stay away from the AVX2495
