Now I understand. It's a built in amplifier. Because every jl amp I've seen is no lower than 2 ohm.  But its built in.  Got it now. 

oh crap, I forgot to write it was a powered sub.  

 

They do have a non powered version also that is wired at 2 ohms.

Haha yes  it all makes sense now

I'm thinking of removing the carpet on the back wall, damping the wall and rear firing the subs.  do you think that would be similar to a down fire setup?  I fell like it would be better than firing them into the back of the seat and console.

You might get some vibration.  And having the subs aimed that way may actuslly (choke) them out. You want the throw of the cone. And doing that I think would restrict it

I may try it both ways just to see what happens.  

 

I'm still trying to figure out how much power to send the tweeters and mids before anything else.

Are you running passive or active ?

they are passive of the head unit right now,  but I want to go 4 way active.

You'll need a dsp or a 6ch amp.    Depending how much you want to spend. 

[Nasty]

Actuslly tbere nkt many active capable 6ch amps. Theres audison and audiocontrol that I know of for sure. Audison might not be enough power.   The audiocontrol is 125x6. Which is fine. You just have to be careful.  Maybe getting a dsp would be best for you and then a jl 6ch.  

 

Welcome to one of the most expensive hobbies

I want to try the new Alpine DSP.  It's a twelve channel with 25w x 8 built in.   I figured I could power the tweeters with the 25w and then get a 4 channel amp for the mids and midbass.  Or I could use the DSP with an oldschool Alpine 3566 six channel amp sending 30w x 4 to the tweeters and mids, and 60w x 2  to the midbass.

Second choice would be better in my opinion. I'm just not an alpine guy haha

When I first read that 1/4 ohm I thought you meant it could be wired 1 or 4 ohms! I considered  firing rearward and as long as you leave enough room between the cone and a hard parallel surface you won't have to worry about preloading (choke them as nasty mentioned)

Hahaha! I've been using Alpine almost exclusively for 20 years.  Here's a picture of some of the older radios I've collected over the years.  That amp on the bottom is a class A from the early 90s that's going to be going in my Corvette.

 

 

Here's the famous 7909J with it's cassette equivalent, 7620J

How much room do you think I would need?
