Was next door to the Eisenhower Metro, but I actually just moved to Springfield, near the mall....or what's left of it.

Nice.....when is the install?

Is it better to utalize 2 sets of RCA at the head for better sound quality? The Alpine actually has 3 sets, but i was thinking to use the front and sub set. The old head only had one set, and i used the through output on the eq215 to the sub amps. If i only use one run from the head, everything passes through the pld1, is that a better idea.

does it make any differece ??

i feel a little dumb

the xs 4600 has 2 sets for imput. so i figure i will be best to use all three sets from the head right??

should i get 2 more pld1's ??

Post by **ttocs** » Mon Jul 12, 2010 11:41 am

going through the deck will give you the sub control both x-over and output controlled with the deck but will not give the advantage of the pld. you can use the lpl on the eq in the same way and use the pld so I would probably go that way personally.

jsayre914 · Post by **jsayre914** » Mon Jul 12, 2010 11:44 am

now i am just rambling....

if i am gonna run the xs4600 bridged into 2 channels through the eq215. the only way that will work is if i use the 1 set of rca through the pld1 then through the eq and then split it at the amp to use the four imputs. and run the sub off the sub output from the head.

there i am done talking outloud...

Post by **ttocs** » Mon Jul 12, 2010 11:50 am

no man split the signal right at the eq. The ix has the ability to use the lpl off of it to control the sub output and then you get the benifit of the pld on both of them.

But now that I think about it doesn't the ix also have a pld built in which is why it has the peak level with input gain? if that is the case then use the sub output to the pld to your amp and the front output to the eq.

jsayre914 · Post by **jsayre914** » Mon Jul 12, 2010 12:22 pm

so i should run it like so?

your set-up sounds nice, can't wait to see some pics... i'm also thinking about adding an lpl knob, can't wait to hear a review.

NewOldStock · Post by **NewOldStock** » Mon Jul 12, 2010 1:48 pm

option C - IMO. That's how I would run it based on what ttocs has said about the eq being able to drive the voltage to the amps... then you would get the benefit of higher input power from the PLD to the subs and the EQ to your fronts.

Post by **stipud** » Mon Jul 12, 2010 2:14 pm

My vote is for B... run the LPL to the EQ

you meant "run the pld1 to the eq" right?

then would you suggest getting another pld1. will i benefit from 2 or is that overkill

Post by **ttocs** » Mon Jul 12, 2010 2:56 pm

you can use the lpl on the eq to control your sub as well, but I would still go option c myself as long as I was correct about the ix having a line driver built in and I am not sure on that. Mine should be here later this week and then I will become an expert on it.

With that option, the 9887 will allow you to choose the x-over freq and the sub output will control the volume, you will not need the lpl for the sub.

Now you could go active and use the eq's variable x-over to control the point the tweeter and mid are seperated, and then you could use the lpl to control the output on the mid to help balance it. This would also save the power that the cross-over normally eats and give you more tunability as well. I am sure that someone will give a link to the article saying to keep the x-over but I love tunability

soooo...

does the eq have a line driver built in???

Post by **ttocs** » Sat Jul 17, 2010 4:33 am

oh, like I said it does have an input and output gain adjustment, both with peak indicator and it can send up to 8 v out to your amps so yes, it does. Also has a time variable time delay of up to 10 ms to help with time correction if you need it, pretty bad little piece IMO>

jsayre914 · Post by **jsayre914** » Sun Jul 18, 2010 11:50 am

I just had an idea.

Option C has the XS 4600 bridged into 2 channels. Each channel would be running the RSD 6.5 components. But, the rsd's are rated at 120 max, so i will not be fully utilizing the amp. What if.....

I Use the front 2 channels of the XS 4600 for the RSD's 75 X 2 and use the rear channels bridged into a 8 inch woofer mounted inside my center console, for more midbass. My current setup has the 2 twelves in the front trunk and the 2 6.5's on the floor (kicks). The 8 inch woofer would get 300 watts and will hide in the cockpit right in your lap

is that weird to have 2 tweets, 2 6.5's, 2 12's and One 8inch??? Would that be an awesome idea, or should i stick with the original.??

introducing option D

jsayre914 · Post by **jsayre914** » Mon Jul 19, 2010 2:23 pm

phoenix gold does not offer a 8 inch woofer that i saw. If I wanted to keep it all pg i need to figure out a different way to use the 4 channel amp.

how can i get some more mid bass and keep it REAL

keep in mind i have never heard the 6.5 componet set before, nor have i purchased it yet....

opinions please

The RSDCs have quite a bit of midbass. If you do plan on adding midbass drivers keep in mind they need to be run in stereo up front beside the components as well, otherwise you draw your bass soundstage to the trunk of the car.

The human ear can localize sounds above 60Hz or so, so ideally you get the components to play as close to that as possible. With the woofer playing below that it blends right in and creates a seamless front stage over the full sound spectrum.

Thank you,

I will scrap that idea. I was looking at components on woofersetc and the Morel Tempo 6 seem to handle a lot more power than the rsd comps for not too much more money??

anyone running those?
