Questions about adding an aftermarket sub to Infinity system
So I want to replace the stock sub, but I have a few nagging questions I can't quite sort out.
The biggest thing has to do with the bass rolloff at higher volumes. What exactly controls this? If I add an aftermarket sub, how do I avoid having the gain cut out when the system reaches higher volumes? Does the rolloff only apply to the sub, or all the speakers?
What about a LOC? I understand most aren't rated for high power input...so what happens when I tap into an amplified signal?
For those who have done it, what exactly did you do? What components (specifically the LOC) did you use? Do you still get the rolloff at higher volumes?
I'm having a tough time getting my head around this all. For a "premium" sound system, it seems quite crippled.

"Crippled" is definately a term I would agree with. I didn't have any luck with a LOC when I first started playing around with changing things, although many people are quite happy with using a LOC to run a new amp and sub. Running a new amp will help give you the boost and fill in that drop off you're describing.

The other option is something like the MTX RE-Q which will normalize the output and get rid of the rolloff, though it's a little on the expensive side
sorry if thats a stupid question

Sorry I didnt read all of the posts.
But you can try a sub with an amp that has an independent bass control. you can go higher or lower depending on the music and bass mhz output.

The downside of a remote gain control like that is you'll be stuck constantly tweaking it if the bass drops off at higher volumes. This is where a unit like the RE-Q becomes very useful.

I made this box for a JL audio 10" sub, and it kicks, all the power wires are made to quick disconnect, I took out the old sub, in its place we mounted a Rockford Fosgate amp. We looked at several options at the audio store and this seemed to be the easiest, better than the Infinity bass link.
