sws8x install with JL xd400/4 install help

[leJUNd]

Hello.
I've been putting this off for two years... but I am going to really do it this time
I am about to purchase sws8x and JLxd400/4 to upgrade my sound system.
I bought Technic's harness and JTSHERRI's spaces so I could DIY the install.
Before I proceed I want to make sure I have everything correct. I am new to this so please bare with me.

Does this look right?


Where do the RCA cable from LOC go on the amp?
Do I need LC2i?

Thank you

Why would you use a 4 channel amp to power two subs?

It goes harness-->LOC-->amp-->speakers.

RCA on LOC go to input on amp.

The LC2i is an LOC.


If you come out of the meet tonight, I can explain it in person if you want.

I want to but so so far and so much traffic...

From reading old threads... I gathered that this was a good combination.
Is it not?

People come from further.

Not sure what thread you read to verify but if you're running two subs, all you need is a two channel amp.

I think the xd400/4 puts out 75 watts per channel at 4 ohms
But if you bridge 2 channels, you get 200w per channel

I think that you got one of the Navone 150W LOCs originally used with my harness. It should work if your OEM amp is the "old" design -silver box with heat sinks on the top. The "new" design is grey box without any heat sinks on top. You will need to tap the OEM remote wire for this install: http://www.m3post.com/forums/showpos...3&postcount=49

Just make sure that you get the SWS-8X and not the SWS-8Xi. The XD400/4 is not 2 ohms stable in bridge mode. A better suggestion -albeit more expensive- is to get a pair of Jehnerts midbass, a Musicar Trunk box and an XD500/3. No need for SWS-8 spacers.

I sent a harness wiring diagram to you at the time of purchase. Please send me your email again if you do not have it.
