Head unit compatibilty with active sub.

[TbM]

You statement here is half right champ.

"MOST" CD/MP3 HU's have L/R For sub-preouts and others shows 1 for SUB PREOUTS. - most likely these units are the high end units (DB Competition series etc) without the output speaker wires - ALL RCA's. FRONT - HIGH/MID/LOW | REAR - HIGH/MID/LOW | SUB - LOW.

DVD Incar entertainment units have only 1 x RCA for SUB-PRE OUTS.

So from what IV73CI is saying is also correct.

I used to work for Autobarn / Harvey Norman on the gcoast as an Installer for 5yrs.

FYI - Here is an example for a YAMAHA Home Receiver for Bludgers quote regarding Home systems etc - L or R RCA can be used - Only 1 RCA though not BOTH for 1 output.

I dont think you read my statment mate, read the first line again.
"most decent aftermarket Hu have 2 channel sub out(non fader), only a couple i seen that dont(mostly AV ones)"
If you notice i did say its av ones that ive seen with 1 channel, as a supposed installer you should know there are far more cd/mp3 units then AV ones so my statement is 100% correct.

I never said they didnt exist just that there are many more cd/mp3 units around than AV. AV means Audio/Visual unit if you dont know, thought id explain that to you cause you dont seem to know much about car audio.

If you dont think there are more cd/mp3 units then AV consider the fact that AV has only started coming in the last few years where as cd/mp3 has been around for a much longer time, common sense would dictate that many more cd/mp3 have been sold so they are in the majority.


IV73CI was not correct, he said you need to run 2 RCA's to the amp requiring a single channel soruce, if you were an installer you should know this is not the case, sub amp powering 1 sub only requires one RCA input, dont need a Y splitter like he was trying to get the OP to waste his hard earned money on.

Working for autobahn/harvey norman doesnt mean you know what your on about, dont know why you needed to include that, Ive been doin audio for over 10 years now so whats your point?

Also never heard of harvey norman(stores near me) installing car stereos and Northfeild are pretty much the only installers i respect in QLD, any muppet can work at autobahn.

Funny that you Neg reped me for that post as ive already recieved many positive reps from it so ozhonda is either full of idiots or looks like your wrong, like IV73CI. Id bet on the latter one.

I worked at harvey norman so i know everything.

Not teaming up on anyone here - just want to point out that simple responses can be easily solved by reading the posts/replies and it does not require a blog of answers to prove whos right or wrong .. ffs.

Your saying that i dont read nor understand the OP or your post,

From reading all the replies on this OP - it appears that vtec is the closest to answer the theory relating to the OP.

Specs of the Active subwoofer:
•Maximum output power: 180W(90Wx2)
•RMS power: 120W(60Wx2)

IV73CI was not correct, he said you need to run 2 RCA's to the amp requiring a single channel soruce, if you were an installer you should know this is not the case, sub amp powering 1 sub only requires one RCA input, dont need a Y splitter like he was trying to get the OP to waste his hard earned money on.

OP refers to 90wx2 or 60wx2 RMS - this means that the built in Active AMP clear shows a 2channel AMP. it doesnt actually say how many subs are connected to this amp but seeing that the amp is a 2ch - it makes sense two subs are connected - Most built in AMP /Sub Active units are suited to match the amp vs sub - I.E 1 sub = 1ch amp or 2subs = 2chan amp sold as a combo/kit.

Therefore the Sub INPUT should be 2x RCA L&R which will require a 3 Y splitter to run the signals from the HU to the AMP L&R due to the 2chan configuration. (VTEC's response to this is correct)


IF you decide to run just 1 RCA from the HU and to the AMP 1 RCA ...then one of the SUB will not work due to a 2chn config - rather than a bridge mode.

The Sony Head unit OP was enquiring about has;
•RCA Audio Output(s) : Front, Rear, and Subwoofer RCA pre-amp outputs

Sub output = 1 x RCA as illustrated from the manual.

i guess the main question that everyone has missed out on is "How many Subs are connected to the amp and how"?..

I dont think you read my statment mate, read the first line again.

i dont doubt your response - hence i said why its half right. but not 100% as you claim.

even if the hu only has one output when you are only running 1 channel(1 sub) you only need 1 input on the amp, generally the white(left ch) input. No need for a y splitter.....

this is the other half which was inaccurate if refered back to OP - but in generallisation YES its correct.

The OP could state 2xchan or 2chan bridged into 1 ...who knows .... but as i mentioned already most Active sub/amp kits are made to match amp & sub characteristics 1:1 ratio ...

Working for autobahn/harvey norman doesnt mean you know what your on about, dont know why you needed to include that, Ive been doin audio for over 10 years now so whats your point?

oh yeh i do know what im on about - im not a guru or a rocket scientists - i included that to let the poster know that i can help if required and if local.

my 5yrs+ are qualified electronics engineering.

your 10yrs+ could just be self taught / self experience / knowledge and installs on own cars / friends etc etc. - i dont doubt that either - and most people start off from this - just like i did.

its not about how long uve been in the game/business - its about sharing WHAT you know from personal / professional experience.

Also never heard of harvey norman(stores near me) installing car stereos and Northfeild are pretty much the only installers i respect in QLD, any muppet can work at autobahn.

were obviously in a difference location from each other. ive heard good things about Northfield too .. no doubt

and yes any muppet can work at autobarn - esp nowadays/generations.

but i was one of the early pioneers part of the early autobarn installers. just an FYI.

Funny that you Neg reped me for that post as ive already recieved many positive reps from it so ozhonda is either full of idiots or looks like your wrong, like IV73CI. Id bet on the latter one.

Why are people so hyped up about rep pointd etc . - i give + or - to posts that i seem right or wrong etc.

i dont rep people because im a hater or jealous etc. i rep whoever the **** i want. and people can do the same.

just gotta remember ppl - this is a online forum - no need to be serious and all and there is definately no need to troll and post up harrassing pics/gifs.

it should be an exciting fun and enjoying experience for everyone without being put down or having a go at someone.

lets all have fun

I have purchased an active subwoofer which has an inbuilt amplifier

He has clearly stated that he has purchased an active subwoofer with inbuilt amp, if he had more than 1 it would of said a pair or set of subwoofers. Even if the amp is 2ch it should be run bridged thus still only needing 1 rca input

He has clearly stated that he has purchased an active subwoofer with inbuilt amp, if he had more than 1 it would of said a paid or set of subwoofers.

why would u pay for an Active sub/amp combo and pay for 1 subs seperately or if it did come with 2 subs? - this is just wrong. - hence why they call it a Active Sub/Amp combo priced as a total package.

Never seen an Active sub using a 2xchannel AMP to run 1 sub. - this is just plain stupid for the manufacturers to even promote to sell. - they will loose money as its not profitable.

Yet again - all this can change if the store has decided to "modifiy" the combo to customer specific requirements.

Even if the amp is 2ch it should be run bridged thus still only needing 1 rca input

you will still need to hook up both L/R RCA's to be in bridge mode. or else only half of the signal/ output voltage power will be experienced. - I.E 5V preout will be half to 2.5V.

was meant to say pair not paid, have edited.
If you refer back to my last post i was trying to point out the he said he got "an active subwoofer" not a pair or set of subs which would imply more than 1 woofer.

Its quite common to use a 2 ch amp to power a sub and run it in bridge.

In my experience you only need to use 1 rca for bridging 2ch together, i currently have a eclipse PA5422 in my civic and it makes no difference weather i hook up both or only left, if you were correct i would have to basicly half my gain if i plugged in the second one, which is not the case, have also installed some kicker and apline amps with the same effect. If you could give an example of a car amp(2 ch in bridge or 4 ch running 1 side bridge) that does require both inputs i would be interested as ive never seen that.

My home sub also works the same, has 2 inputs but if i use a y splitter it has no difference to just using the white/L input.

It seems like this thread has turned into a mess of debates, I have read through it all and each post has contributed to my understanding on car audio.

Also to clear things up i added a link to the active subwoofer i purchased.

Thanks for the help guys !

Sorry for the mess in your thread but if i see someone giving incorrect info ill call them on it.

Thanks for posting up the active sub, confirms that i was correct that its a single sub using a 2 channel amp, unless its been setup to run a channel to each coil then you will only need the 1 sub output from the headunit connected to the white/L channel of the amp. no need for y splitter.

If it has been setup to use a channel each coil then you would need a y splitter but i have never seen this done and it would be illogical of manufactures to run it in stereo when your using a mono/non fader input. Would explain why but i think there has been enough in this thread.

To answer your original questions,
Yes the sub and headunit will be compatible

You will be able to use the stock speakers and power them by the headunits internal amp

Taken from http://www.crutchfield.com/S-AZcrmDN...fo#details-tab
"Steering Wheel Remote Compatibility: The headunit features an OEM steering wheel remote control input on the rear of the unit to allow you to keep your vehicle's radio steering wheel remote controls when used with the optional PAC SWI-PS Steering Wheel Control Interface Adapter (127SWIPS, sold separately); or the optional Metra ASWC Steering Wheel Control Interface Adapter (120ASWC, sold separately)."
Search those model numbers to see if your car is compatable

Havent installed a stereo in an fd2 so i dont know how the aux is set-up so i dont know if you can or cant reuse aux port sorry.

Hope that helps.
