I meant how is your amp getting signal. ARe you using loc, lc2i, or wire straight from back of head unit etc..

how is your amp hooked up/ loc or lc2I?

i'm going back n forth whether I want to buy a T- harness from net audio, put a loc tap into rear speakers and use rear cig lighter or buy lc2i.

is bass roll off that big a deal on these trucks?


how do the seal boxes sound? I listen to more county n rock.

I have a 4 channel I tapped the rear of the deck and ran to the amp using the high level input then rca from the 4 channel to the sub amp however I would recommend a t harness and loc I didnt know t harnesses were available when I tapped mine and I am going to be switching from the high level input to an lc7i or lcq1 for better adjustability cleaner bass then the high allows

Tapped the wires off the back of the head unit. Like I said though if i could do it over I would go t harness and lc7 or if you are only adding a sub amp in your case use the lc2. I think the even offer a pre wired loc as an option with the t harness!

how bad is the bass roll off ? this harness wouldn't have the ability to adjust for bass roll off, but is it necessary to get lc2i to adjust?

 

[FF1899]

I have never used an lc2 however I would assume it helps with the adjustability some vs just the amp settings and high pass filter. I believe it sums the audio from the input channels giving better signal. I would enquire with someone who uses the audio control products because I haven't switched over yet

 

[Ecofx86]

so u have your sub amp getting rca from your high amp, high amp getting signal using high line out from back of deck?

 

[FF1899]

Affirmative. My 4 channel has a output RCA running to the mono amp

 

[Tim Garceau]

I tapped into my sub wires with an RF-HLC and have zero low end filtering using RCA's directly to the amp. Maybe below 20 hertz there's roll off, but that is not usable in most of my music/audio and having a gain dial directly under the console makes it negligible IMO.

This might not be apples to apples if you're doing active/passive components so I apologize for not reading the entire thread.

all I did so far was change all speakers to kickers running off stock 8.4 non alpine. im thinking about adding 4 channel amp. Which speakers u have hooked to your 4 channel amp? the dash n front door speakers are connected together so u have to make a choice their when adding a 4 channel correct?

so its not worth getting lc2i if bass roll off is not that terrible. I could just buy t harness with loc and call it a day.

did u need to add resistors to speaker wires for the 4 channel amp ? doesn't the 8.4 unit kill power to speaker output if u don't?

I have a single ported 10'' Fox box... I had to plug the port hole because I was getting very muddy, long bass notes and the port noise was driving me insane. Now that the port is plugged my bass sounds much tighter and more precise.

I cant say enough good things about Fox Acoustics though. Great quality and great craftsmanship, and they're located in my home state!

 

[Ecofx86]

fox is located in Louisiana?

I guess it wouldn't take too long to a box shipped from Houma to Lafayette lol

Im thinking of going sealed 12 inch box.

I am using a Audio Control LC6I for the signal to the amp. WIred up behind the radio to the LC6I. Then RCA to the amp.

How did you plug it? I was thinking about trying on mine but worried about rattles coming from it, leaking or screwing up the box

I stuffed the hole with a grout sponge first. It was about 2'' thick and conformed to the size of the hole really good. Then I cut a piece of 3/8'' Lauan that fit all the way down the length of the box. I Siliconed around where the Lauan met the Fox box just to seal it off better. Then I used short sheet rock screws to screw the new board down.

I used a sponge inside the port hole because I was worried about all that pressure blowing through the Lauan. In my head, the sponge acts as a kind of barrier between the sound waves and the thin plywood covering the hole.

I still may paint the Lauan with bedliner just to match the Fox Box.


Notice in the last picture how I raised my seat up a bit with a couple of the kids' Legos... Worked perfectly!

LOL. Another Swamp Footer! Ill be damned.

If you get the sealed 12'' dont get the adapter ring to fit for a 10''... It raises the sub up too much and it will contact the bottom of your seat, even with the spacers they provide.

Ah. It probably didn't sound very good because the air space requirement for that sub is a lot more than the volume of the enclosure. You were choking it to death. And getting tons of port noise from running stuff below the 36 hz tuning frequency. Sealed up, it should be about right. Glad you got it sounding decent. I don't have any issues with my RE Audio sub, but I also don't play low stuff. Rock and metal only hit my sub. With the occasional old school rap, but none of that new garbage.

I have a crew cab

Tel me if u think this would work..

use lc2i get left and right signal from rear speakers. hook Rca from lc21 to Mon block amp. use 12v n ground off mono amp, use rear cig light for remote.

Say I want to run a 4 channel amp down the road, could I just use the mono block output rca to connect to the 4 channel amp. I would lose fade but I would keep right to left? correct? From 4 channel amp run new wires to front n rear speakers, leave dash (3 1/2 )connected to factory radio. Install resistors where the front speakers are so the radio will play dash speakers.

what you guys think?

Check out the new Michael Romeo solo CD. Specifically the track ******* Robots. I think you'll be surprised by the low end.

Play it loud.

I think you'll be happier in the long run if you start with an lc6i or similar. That way you'll already have the ability to wire it correctly when you decide to add the four channel later. Pulling the mono signal out of the sub amp will sound like crap.

Better bet (if you're using the lc2i) is to do it the opposite way with the lc2i and run into the 4 channel then pull from that to the sub amp. You'll lose fader but at least you'll still have stereo.
