i bought my basslink from EBAY 165 SHIPPED!... and its posed to come within the week.. i was wondering... HOW DO I INSTALL IT ON A 2005 SE Civic's stock system... there are no outputs from the head unit.. i know i have to splice wires or something like that... I can and have installed speakers, and head units B4 but never an amp or a sub b4... ANYONE WITH A STEP BY STEP on how to do this... plzzz postttt ... i also have the remote for it so plzzz post how to install! =]

Just cut off the RCA ends and splice them in with a rear speaker wire. Then run the power, ground, and remote wires like normal.

no no no dont do that you will kill your amp. get ahold of a line convertor. it will turn speaker level into low level inputs. then just run a short patch cable to your amp. run your power line from your bat. and a remote line from your fuse box.

wait wth!... im confuseddd now.... plzzz clear things up for mee... remember ima newb... and im really lost wit these 2 answers =/

dont cut rca cables and conect to your speakers and then to your amp
it will let to much power into your amp and will blow it.
low level inputs on amps are made to handle like 7-12 watts
thats why they sell line convertors. it will convert your 30 or 40 watts
down to like 10 watts.
alot (good bit of them anyways) of low pass crossovers (just lets the bass through
and cancels out the highs)
have speaker level input, but they all have line level (low level) output.
hope this helps you a bit better. if ya need any help just ask.

JUST LIKE I SAID!!![:@][:@][:@]

i thoght the basslink came with that built inside already?... thats wat someone else told me but im not sure.... can u check for me... www.infinitysystems.com

Yea, the basslink does have a converter. Its a little term called "LINE LEVEL INPUTS". Thus, you dont need an external converter since it already has one. Another bonus is that the amp on the basslink wont need a remote wire going to the head unit to tell the amp when to turn on and off. It detects sound automatically : ) .

Oh, and one more tech talkie. The bass link features a Harmon Kardon class D amp which not only barely heats up, it is much better for smooth transitional bass! Oh yea, it also uses less juice than a class a/b amp would at the same power rate. I love class d amps!

wow u speak very highly of the basslink! ahah makes me feel happy i got it!!!!!!!! =] ... anyways... REMINGTON! can u plzzz help me like a walk through on how to install it... plzzzzzzz post!!!!!!!!!!!! =]]]]]]

But wait... you don't plug a speaker-level signal into a line-level input.
The Basslink does have speaker-level inputs, so if all you have to work with is an amplified signal, then you need to use the speaker-level inputs.

This is from the Basslink owner's manual which you can find here if you don't have it: http://manuals.harman.com/INF/CAR/Owner%27s%20Manual/BassLink%20om.pdf
Head units with four speaker-level outputs: Connect the four speaker-level outputs from the head unit to the four Universal Interface inputs on BassLink.

oh man... in noob terms plzzzz

damn here it is a formal i'm sorry goes out to steven for me being a jackass a few post up

its cool dude...just help meee outttt ahahahah =]

my amp has all the line inputws too but the guys a circuit city couldn't do my install untill i bought the peice and then he told me that he was just gonna splice wires and if he was me he wouldn't pay 65 bucks for it so i pulled a DIY

its cool dude...just help meee outttt ahahahah =]

thats what im sayin.. i dunt knwo how to splice wires... or anything like that.. connect to power etc... if u show me i can do it... i can install headunits and speakers.. so i think i can do this too.. i just need a lil tutorial

I have to strongly dissagree there. What you just said complelty eliminates the entire point of the line level input. What would it be used for other wise? Its called "high pass" on most amps. It is designed to regulate the flucuating watts for the amp to a constant state. IT IS SPECIFICALLY DESIGNED FOR SPLICING FROM/ OFF OF SPEAKERS. This can be a life saver for those who are leasing vehicles


And yes, steve, I will be more than happy to help ya out. Ill walk you through it.

Before you start, youre going to need

butt connectors, some 16 guage speaker wire. And some stipper/ crimpers (some even come with a few butt connectors) . Oh yea, dont forget your screwdriver. ;)

I'm saying that you plug a line level signal into a line level input
And you plug a speaker level signal into the speaker level input.

Which part do you disagree with?

Unless car audio terminology is vastly different from live audio terminology, I don't think I'm way off base here... not trying to pick a fight or anything

thanks a lot!... ok.. i have all my wires... my basslink... and the remote for my basslink... WHAT NEXT!????????? hahaha im exciteddddddd

I think you are referring "line level" input as "Low Pass" a.k.a. RCA inputs

Line Level a.k.a. "High Pass" is what you are refering to "Speaker Level Input" .

So I think terminolgies differ a little bit but I couldnt really say for live audio because it is a complelty different animal.

No fights trying to be picked ;) , geez... do I really bite that hard? I didnt mean to if I did.

You need a drill and self tapping screws also, im pming you right now for my number if you would like live step by step help, you lucky bastard... I never got that kind of help[:o] but I like helping. Feel free to call buddy.

Line Level a.k.a. "High Pass" is what you are refering to "Speaker Level Input" .


omg, that makes my brain hurt!

Where I come from, in the land of live audio, this is the deal:
a line level signal is used to interconnect pieces of audio processing equipment -- mixers, EQs, compressors, etc -- everything puts out and expects to receive a line level signal. Amplifiers take the line level signal and increase it to a speaker level signal. Obviously you can't use a line level signal to drive a speaker because it is not powerful enough. And you can't send an amplified (speaker level) signal into something that is expecting a line level signal, because it will be too powerful. In the case of our friend Steven here, the RCA inputs on his Basslink are expecting a line level, unamplified signal (because it will go through some signal processing and then into the internal amp). He can plug a speaker level, amplified signal into the "universal interface" jacks which, presumably, convert the signal back down to line level before processing and then re-amplifying it. And in this case, I think the Basslink is agreeing with me on the terminology, and not with Remington, because the specs say
Input Sensitivity:
50mV – 4V Line-Level Input
1V – 16V Universal Interface
so the line level inputs want to see a lower level signal, and the Universal Interface inputs want to see a higher level signal.

Also, regarding high pass and low pass: I have only heard these terms used in regards to high pass filters and low pass filters, which cut out the low frequencies and high frequencies (respectively) of audio signals.




I didn't think you were trying to pick a fight! [sm=itsok.gif]

edit: Remington, I figure you knew this already (even though the terminology is different for whatever reason) but I wanted to give the long explanation for anyone else who might be reading this :)

i was wondering which method sounds better? i heard i can splice the wires and do a connection into the basslink OR splice wires into a line level thing and then connect as RCA's?... will the quality difference be noticable? which ones bETTER?!!?!?!?!?!?

I would think that the line level converter inside the Basslink should be trustworthy.

so i should just splice and insert correcT??

Basically. I'm sure Remy will give you details iff you call him, I've never done an installation like that before.

Do you have the "universal interface" wiring harness? I bought my Basslink used and it did not come with one. Just wondering what it looks like.

you need to get power back there too! unless you have done that already

no actually i havnt done anything yet! hahah im just tryin to sort erverything out so i can do it faster and actually know what im doing when i do it

Steve, cutting up patch cables (aka RCA plugs) and splicing them with wire is sorta ghetto. Now the high pass inputs should be fine... has been with me.

keep us updated

well my basslink came yesterday and im installin tomorrow...i hope i can do it!...ahha the guy i boughtt off of on ebay gave me all the wires he used... i took a quick look and there red.... should i use his?... or go get some fresh wires to be safe?....

get fresh wires he might have cheap wires frayed or what not i'ld get new ones but you can always wait and see if they are good to go

I think you are referring "line level" input as "Low Pass" a.k.a. RCA inputs

Line Level a.k.a. "High Pass" is what you are refering to "Speaker Level Input" .



The way I always understood things... low pass and high pass refer to frequencies. As in, low pass filter (lets in bass) and high pass filter (lets in higher frequencies)

OMG terrible newsssss... when splicing the wire...i snipped it... the original speaker wire goin to the speaker is too short now!.. i have no rear speakerssss... !!! =[ what can i do!?...it was the last step in installin... everything else is done... the ground...everything!..=[ plzzzz helpppp

that just means you gotta do a little more splicing than you were planning on calm down it's no crisis and yes i'm still @ work

Read it and weep, folks.......here it is from Infinity themselves:

Designed to deliver low frequencies in virtually any car audio system, BassLink truly has universal appeal. Small in size but big in output, BassLink requires a mere .75 cubic feet of trunk space yet produces enough bass to wake up the neighborhood.

BassLink consists of a 10-inch subwoofer, 10-inch passive radiator and a 200-watt Class D amplifier housed in a rigid polymer enclosure, all carefully engineered to work together as a unique, integrated system. The extremely versatile BassLink accepts both speaker- and line-level inputs, and it provides an internal low-pass filter, proprietary signal processing and abundant amplification.

The BassLink system features a servo-control circuit that continually monitors the voice coil’s position in the magnetic gap and prevents the distortion that occurs when a conventional woofer is overdriven. By integrating cone-excursion information with the instantaneous demands of the music, BassLink can extract loud and deep bass from an enclosure smaller than any before.

BassLink includes a fixed, 2nd-order, high-pass filter that eliminates the possibility of over-excursion below Fb, the resonant (tuned) frequency of the vented box. This allows the excursion-monitoring circuit to focus on the excursion at the more meaningful frequencies at and above Fb. The result is a significant increase in bass output.

User-adjustable controls allow listeners to set the system’s response to achieve optimum performance based on the vehicle’s cabin gain or transfer function. These controls include: a 0- or 180-degree phase switch; a continuously variable electronic low-pass filter that is adjustable between 70 and 100Hz; variable input sensitivity; and Bass EQ that provides for adjustments between +3 and –6dB. BassLink’s frequency response in a typical vehicle is 20 to 100Hz (±3dB), but this varies according to the vehicle and user adjustments. At maximum gain, the system can accept inputs as low as 250mV.

BassLink can accept up to four channels of input – to provide nonfading bass – either from line-level signals through four RCA jacks or from high-level signals through a pair of Molex connectors, allowing BassLink to be easily connected to OEM systems. If using the speaker-level inputs, an audio-sense circuit will turn on the amplifier whenever a signal is present. If the RCAs are used, a 12-volt, remote-turn-on lead is required. The system has barrier strip connections for power, ground and remote turn-on.

Okay, Stevie, you're gonna have to try your hardest and cut some insulation off of that "too short" original speaker wire and then splice another piece of wire onto it to lengthen (if needed). The best thing for a newbie installer such as yourself, is to invest in a nice wire stripper that does everything for you and you can't cut the wires anymore. Just make sure whenever you splice a wire, that it ends up being a nice secure joint. The best thing to do for a solid connection is to solder any splice.

so all i have to do is extend it with a piece of speaker wire?... i have extra speaker wire in the one that goes to the basslink.... can i cutt a piece off that to extend?... also.. wats the wiring colors foor the05 ciivic.... blue/yellow? positive? etc.

Yes, just extend it, unless the Basslink wire is long enough, then just splice to that instead of having a little extension piece spliced in.

that ****s tighttt! omg...mad props 2 everyone that helped especially maddawg.. man i was callin him foor help at like 11 PM thanks man... i extended it and it is perfect!... thanks so much ever1 that helpedddd

Glad we were able to help. That's what this forum is all about.

hey i have one lastquestion...umm u know how the car has like little slots that are empty underneaath the head unit?... like just black squares...imi wondering if its possible to pop that out and stick my remote in there foor the bass

also.... ima newb so like i dunt know wat the crossover means... and i dont know what the phase switch at the bottomm means...

Congrats... The phase and all that stuff is just for tuning the sub to make it sound better to your liking. I like to have the crossover about 1/2 up and the phase all the way down... end run makes great mooth bass!
