Sub to stock head unit

[Kenneth]

Hi there,

Im thinking of hookin up a sub to my current stock head unit (03 corolla ascent).

I would hv spent money on a sub and an amp (saperately) but i was thinking i only need it temp as i would save up for something better later (new HU,sub,amp n everything) so i came across this on ebay

Sub with amp (Click here)

I was just wondering if anyone know how to hook it up to the stock HU.

It only has HIGH input/output and then RCA (which im sure the stock head unit wouldnt hv one of those).

Any advice would be much appreciated! thank you!

hey there dude, i did mine wit a sperate sub and amp but im sure with wat u got it doesnt matter, now with ur high imputs\outputs u need the plug that goes in2 that. now the + and - hooks up 2 the speaker wires jus connect post and neg up and it should work. U dont need a remote wire, well mine doesnt have it!!

ok ummmm..... let me knw ill get bak 2 u more later unless someone has helped

gotta go movies are starting

i use to run sub and amp with factory head unit. I had to get power cable to connect to the battery for the amp, reomote wire and RCA converter to connect the head unit and the amp..

hope that helps

so basically you saying that it would work if i connect up my speakers to the high imput? haha because i thot you needed a low input for a sub but yeh :) just wondering..

@Hsien - wht do u mean by remote wire and does the rca converter just converts the RCA from the sub so it would fit on to the stock head unit?

thanks

[kym11m]

all u need 2 do is tap into say ur rear speaker wires +/- (mine are tapped in2 the front speakers) and wit the plug u get that goes in2 the HIGH IMPUT (not 100% on the h/output, dont think u need it) them wires u solder up 2 both right and left side speaker wires.

im not 2 sure bout the low imputs but high sounds better :P :P :P

yes u need all ur power cables from +/- but u dnt need remote wire........

.....i dnt use a remote wire and mine turns off wen the car is turned off........ im thinkin it has 2 do wit the speaker wires that u tapp in2.

let me knw how u go

Sorry guys, this has been covered a squiilion times before....

Anyway, if you connect through the Low Pass (RCA) then this will always be a better avenue as the signal is clearer, however, as we all know, the stock HU does not have RCA out...

What I have done in my car, is located the rear speaker wires in the B Pillars, and spliced into these and diverted the signal to split it between the rear speakers, then off to my high pass on my amp.

Ok, the sound is not as great as a low pass output from a decent HU, but it works for me....

[JJCRU23R]

damn you toyota for not adding RCAz to our hu'z!

thats all i have 2 say about that.

all i have on my amp is RCA inputs with a switch above it that says high/low input. so how would i connect RCAs to a spliced rear speaker? is that possible?

i cracked open my right hand rear door and saw the speaker cables that lead to the rear speaker.. they are thin az!

[Azza]

You can convert from RCA to std line with a converter, I think you get them from Autobarn, Tandy's, ***** Smith or something for like $25 or something.

Weird it only has Low Pass input....

they are thin az!

As opposed to thick az, like me hahahahahahahah

na what i meant was that the switch is there so you can choose whether you want the amp to work on either high or low input, while using the same 2 RCA (red/black) plugs.

ANYWAYZ...

after that last post i made i did come to that realisation that there MUST be a way of connecting a sub to a stock HU. after searching the forumz and reading the other threads bout DIY sub to stock HU, they didnt offer proper solutionz and i knew there had 2 b a better way but i didnt know what... so i rocked up to autobarn bout 3pm and found exactly what u were talkin bout azza... but yea $14.95 for the converter!

i pulled out the sub wiring out of my landcru23r and yea its sitting in my boot waitin 2 be wired up.

i hooked up my kicker in my brothers celica to see how the sub looked and sounded when it was powered up.. but yea his amp is much higher wattz than my lil kicker should handle so i kept the volume low hahaha! least it works. he needs 2 get this RCA converter 2 coz his sub is connected to 1 of his speakers coz he has a stock HU as well.

as long as it works properly, its fine with me. ill hook this thing up tonight when i get home but im still at work.

thankx 4 ur help azza, even though your post came up like at almost exact same time i was already at the shops picking up the converter :)) i got the recipt 2 prove it too if ya dont believe me :P

great mindz think alike ay?

Gotta love the JD overweight woofer from ebay for only 65 bucks

[Azza]

Good work Jase,

Glad I could help

[Kenneth]

@azza - i looked at the cables @ b pillars and they seems pretty tight and i wsnt sure how exactly to tap another cable in (incase i stuff up :S those cable are gone hahaha)

looks liike a new challenge to me :P

[selyaT]

Dude do NOT pay $175 for that.

Take a look at my garage/members ride and see how much I payed for mine. Also check that it's the same one 'cos that pic on ebay isn't loading up for me. It says:

JD

OVERWEIGHT WOOFER on it.

It's probably worth the 70 odd bucks I payed for it but please don't pay anything over $100!!!

Not as good as they make it out - not that I was expecting that :D

[Kenneth]

oh nah.. im not going to pay 175 for tht.. hmm there is 125 on buy it now but yeh i was doubting it but yeh..another option is to get a saperate amp n sub (which i think i would do..)

thanks neway :D hehe.. but connecting it all up to the head unit is gna be smething rather hard when i hv next to no experience with it :P

i hooked up my kicker sub and cheapo amp just a few days ago for the first time in my rollas stock stereo. ive done it b4 on my old car but that was easier since i had a JVC cd player in my landcruiser which had the RCA plugs on it already.

since our stock headunits dont have RCA outputs, go 2 autobarn for a

AERPRO Speaker to Line Level Converter - AP304 = only $14.95!

the converter has 4 wires which you need to connect with your front left & right speakers (+/-) wires.

just splice the speaker wires and solder the converter wires on, then cover the exposed wires back up with electrical tape.

ALSO, if your amp doesnt power up after its all wired its probebly coz you may not have connected the "remote" wire on the amp 2 anything.

there was all different advice in here bout that but i connected my remote wire to the +12volt ignition wire.

if your amp works anyway without connecting this remote wire, then dont worry bout connecting it.

check here 2 make sure youre soldering on the correct wires :P look @ "1987 and newer"

http://au.toyotaownersclub.com/forums/inde...?showtopic=4060

all the other instructions are found somewhere in these forums, just gotta search 4 em.. but 4 me, putting in the converter was the missing peice of the puzzle.

i dont remmber seeing advice for the rest of the wiring up for the amp in here, but if you need any help i may b able 2 post some pics if you are unsure of where 2 feed the wires from the battery through to the inside of your car, hiding all the wires etc.

even though the wiring kits and the converter has diagrams, it helpz 2 see actual pics 2 go with the diagram u know?

hey jase, thanks heaps for the advise! haha doing it the 1st time is rather tricky :P hehe.. thanks for the help people..

hiding the wiring wont be much of an issue but it would be good to see how to feed the wire around the area, did u have to take your head unit out so u could connect all the cable? coz the one on B pillars were really tight (is there any way to loosen them up so i could cut and splice them easily.)

another thing is im rather confused. i've heard the term remote wires quite a bit, i tried google searching it but it didnt help much hmm

for the amp connecton ....

1. if i get the RCA converter i need to solder 4 wires? (do i need to do both side - left and right speakers? or can i only do one coz tht might be easier but i dnt know if tht would change things and its ok if i tap in to the back ones rite?)

2. take the head unit out? (find this bit tricky, need to find an extension to the "screw" thing, mine is simply too short to reach :P)

3. connect up the amp power wire to the HU? (if its needed..)

should i do all cuttin n splicing behind the HU or some around the B pillars n some @ the HU?

thanks :D

* some pics would help a lot! Thankssss heaps! i will post pic along the way when i start on it :P

well on your amp u should be able 2 see that to power the amp, you need 2 connect 3 wires. the positive wire (on my wire kit its thick REDwire), ground wire (thickBROWNwire), then the remote wire (thinBLUEwire). the amp needs to be connected 2 the head unit via the remote in order to tell when the stereo is in use. if the stereo is off, the amp would also shut itself off. simple enough right?

if i described the function of the remote wire incorrectly, please feel free 2 correct me :/

as for the converter, my guess is it wont matter if you connect it 2 the front or the rear speakers. but i chose not 2 f*ck round with straight 4ward instructions and soldered the wires directly behind the HU itself.

as 4 finding the wires in the B pillar.. i hear every1 saying i should connect it that way, but since i plan on upgrading my headunit later on, i thought now would be a good oppertunity 2 see how 2 get the head unit out.

behind the HU, all the wires i need 2 solder into are there; and when i upgrade my HU im going 2 need those RCA cables to reach behind the HU anyway! plus i already have the proper RCA cables that can reach from the boot 2 the dash, so yea i dont want 2 lay the cables down twice! just do the job right the first time and be done with it. and when i do eventually upgrade the head unit, itll be straight plug n play coz all the wires are where i need them 2 b.

the only 2 cables that should connect 2 your HU from your amp is the RCA and the REMOTE.

amp gets power direct from the battery with the + wire (with in-line fuse).

the ground wire connects 2 the nearest bolt that you can connect it to.

the remote.. ya i went through that already.

yea i had my dads sidchrome extension knob thingy laying round so yea thats what i used 4 unscrewing the HU.

ill add pics later..

[Kenneth]

ah i see :D now thts heaps clearer! thanks ey

wht i was confused was how to connect the amp..

so the inline fuse will go straight to the battery.. sounds good i will go round to straffield or super cheap to look for one of those :)

so the remote wire from the amp will connect to the ignition wire on the HU?

thanks :D

[JJCRU23R]

so the remote wire from the amp will connect to the ignition wire on the HU?

yep, the remote wire should connect 2 the ignition wire thats right next 2 the speaker wires behind the HU.

Heres a couple pics thatll hopefully explain how i connnected the positive wire and fuse to the battery

although the fuse looks like its just hanging loose in there, the wire itself is cable tied in places so its definately not going 2 move anywhere.

2 make life easier 4 u when installing the converter and this positive wire, you gotta get your HU out, and remove the glovebox.

***2 remove glovebox, unscrew the 1 screw thats located on the left side... grab the left and right walls of the glove box and PULL the fcuker 2wards you. should pop straight out with the right amount of force.***

by sitting in the passenger seat and looking into the cavity where your glovebox was, you still wont be able 2 see the hole you are feeding the wire into! theres 2 much crap in the way for you 2 see that hole clearly. not even with a mirror.. tried that.. wasnt any use. all you got 2 do is jiggle the wire around and continue feeding the wire through.. eventually you should see the end of the wire hanging down near your feet and you can pull the wire the rest of the way.

thanks jace, those pic looks awesome :D now i know wht i need hahah.. but yeh.. my friend asked me to ask around see how much ppl would do it for..

i suppose if its round 100 - 150 i wont mind getitng it done by ppl tht know but other then that im sticking with the DIY method :D

well, my friend just offered to sell me his 500W amp and a 15' kicker competition sub for 200 bucks (which i think its good price)

because lookin around i saw a 150W pioneer sub for 140 bucks then a 12inch sub would cost me another 130 - 150.. so 200 tht lot up thr is good to me :)

but prob is i was wondering.. if the head unit is going to chicken out on that big sub? haha or it doesnt matter since the amp is doing the job and how would it be like if i u hv a 15 inch down a back of a corolla hatch :S i think its bit too much but hmm managable?? hahah
