    Default connecting more than 1 component to a channel?

    I'm wondering how i would connect more than one set of speakers to the same channel, so there will be 4 front speakers, and 4 rear speakers. Is this done via the amp, or would you just twitch the wires at the H/U...? I ask because i've installed a set of Kicker 6x9's on the rear shelf, and a pair of Sony 6Inch splits, in the factory rear locations. I also have 2 pairs of Jaycar Kevlar's which i want to fit to the front and rear doors, and run them as the front channel. I have 2 4channel amps for it, but i've only previously perfomed 1 instalation in the past, where no amplifier was used. So i'm still in the learning cause of things, and really dont want to damage any components...

    Ok so let me get this straight, you wanna run a total of 8 speakers off a 4 channel amplifier?

    If this is the case i cant see too much of a problem here providing the amplifier youre planning on using is 2 ohm stable (it should say in the specs 4 x * watts rms @ 2 ohm as well as 4 ohm).

    Just another question, where have you installed the Sony 6" splits in the factory locations if youve already got Kicker 6x9s on the parcel shelf? Have you got 2 pairs of speakers on the parcel shelf?

    Also, Youre gonna have a hell of alot of sound coming from the rear, with 3 x pairs of speakers there and only 1 pair in the front. Man thats WAY too many speakers. Ive got a pair of Jaycar 6" splits in my front doors and theyre getting around 150wrms and its plenty loud enough, they even keep up with 2 x 15s and 4000w at well over 145db.

    no no, there's 2 4channel amps , not 1. Yeah theres 2 pairs on the back, the 6x9's on the shelf in the centre, and the splits in the factory holes at the back ( yes i cut the metal on the shelf for the 6x9's ) I figured 8 speakers off two 4 channel amps would be fine, and i thought if i put the other splits on the back doors, then they would probably be equal distance away from me as the fronts. Either that or custom pods for the front which i would love, but they seems very expensive to have made.

    I'm not quite following. You have two 4 channel amps which means 8 channels and a total of 8 speakers, so whats the problem?

    Yeah sorry i'll start again i don't think i expalined it very well. Yes two amps, 8 channels, 8 speakers, so that's all good. The question- do i connect the speaker wires to the output on the amp, and just run the RCa's , do i have to connnect the speaker wires in the wiring harness to anywhere, .... that's where i'm confused.. i apologise for not explaining clearly at the start.

    OK....

    As you'll be running effectively 6 rear speakers and 2 fronts, you'll need to run 2 pairs of RCAs from the head-unit (front and rear outputs - i hope you have them). The rear RCAs go to the first amp, using RCA splitters they split from 2 plugs into 4 plugs, which then plug into the amp. This amp powers the rear parcel shelf speakers, so connect the wires coming from each speaker to each output on the amp (making sure to connect the left and right channels properly).

    The front pair of RCAs go to the second amplifier, where they again split into 4 plugs using RCA splitters. This amp runs the front mounted splits and the rear door splits. So connect the front and rear door splits to the outputs of this amp.


    As far as speaker wiring and harnesses go, have you ran speaker wiring to each speaker youve installed? I would suggest to do this and mark each wire what speaker it is (i.e. left rear parcel shelf 6x9) etc.

    I would suggest that when you are in the car and driving normally that you disconnect the amp (just remove RCAs) driving the parcel tray speakers. Otherwise the sound will all be behind you and won't sound so good.

    It would be better to remove the remote cable and tape it up or better yet pull the fuses. You run the risk of the RCAs touching metal by just unplugging them (suppose you could tape them up also).

    Honestly i dont see the point of so many speakers, a set of splits in the front and if you havent got a sub then 6x9s in the back with a good 4ch. running them will sound a whole lot better and is much less wiring etc.

    Each to their own i suppose.

    I might just go the extra front door pods, have 2 pair splits in the front, and the splits and 6x9's in the back. I really didn't think 8 speakers properly amplified, would be a bad thing?? the more speakers the louder right? though i do understand about too much sound coming from the rear. One last thing, i do want to get a sub, so if there's going to be 3 amps, this wont be too much for the battery and normal driving will it? the sub i looked at (and can afford-) is a kenwood 400watt, is it safe to just feed it 300watt, amp being used is a kicker monoblock-rated at 300watt rms ive heard it's not so good to go underpowering your subs,

    Most people think the more the better, so youre not along in thinking this. Basically if you do run both sets of Response splits in the front doors it'll sound a whole heap better than speakers mounted in every possible location. I must stress that rear mounted speakers, be it in the rear doors or parcel shelf are for rear seat passengers only.
    Buy two sets of the Aerpro 6" speaker pods (the fibreglass ones that are covered in vinyl) and install them in the front.

    The fact you'll have three amps wont be too much of a drain on the battery, just be aware when playing the system with the engine off, i'd imagine with a stock battery and the system playing 3/4-full volume it'll last 10-15 minutes before you wont be able to start the car. If you wanna turn the system up, run the car is what im trying to say.

    As far as the 300wrms going into a 400w Kenwood sub, it should be fine....you could run 50wrms into it but the main thing to remember is with less power its easier to cause the amp/sub to distort, and thats what causes damage. By the way is that sub 400wrms or 400w peak?

    the sub is 400watt RMS, i'm not sure what the peak power is, peak doesnt really matter all that much does it?...so long as 300watt RMS amp is suitable , then i'll buy it, as it's about all i can afford at the moment. I looked at jb hi fi, at speaker pods, they were $170 a pair, does this sound resonable, i'm thinking that, $340 (2 pairs) for that kind of money i would expect something custom made for me....maybe i have too high expectations

    $170 a pair, WTF? Last time I looked at JB Hi-Fi they were about $30-$40 each!!

    A little trick that can save alot of buggering around with running new speaker wires to the doors, is to run the rca's and the speaker wires together to the same location(ie- from the head deck to the amp) that ways its only one tear down of the cars interior. Just plug in rca's and plug new speaker wires into the factory plug behind the head unit from the amp.

    Nah mate those pods are WAY too expensive, as acarmody said....$30-$40 each sounds better to me.

    i thought they were too much, this was JB at miranda, i went to ryda, they were expensive aswell, cheapest ones they could give me were $100, they were missing the vinyl and they only had one pair of them.. I might just have to find an aerpro dealer and purchase them through them if i can. I'm gonna skpi the sub for a while, i dont really think that the single 12 on its own will really keep up with the rest once it's installed. I'm better of waiting a while, and getting something really decent the first time around. Even though threre's most likely suffieicient clearance with those spacers, i've been told it's a good idea to cut a hole in the door behind the spearer anyway, as it improves the SQ, is this true. Would worry me cutting so more holes, seems i have thing for doing that already...!

    Yeah, you'll have to cut holes in the door interior and probably the door itself to fit the woofers in. They need an "enclosure" to produce good bass (really, mid bass) and the door cavity acts like an enclosure.

    Youre on the right track by waiting to purchase a subwoofer and amplifier....if you buy cheap crap first you'll probably end up getting rid of that and buying better stuff anyway, so you might as well just buy the good satuff straight up and save yourself the money.......if that makes sense

    im glad i didnt get the sub, my girlfriend got a tv from jb on interest free, so i grabbed some amps at the same time, as my credt rating is f@#$!d, they only had a small range of subs, all either 12 or 15 inch, but i really want a good qualtity 10 inch, or maybe 2.. most of the subs sold at jb were pre-boxed, and after checking online at other places for sub prices on its own, turns out the sub was only worth $120, but boxed at jb was $327, so i'd pe paying $207 just for a box!!! man those guy's can really rip you off, ive heard some pretty bad things about them, particulary with thier instalations... I'll keep the speakers and amps i got from there ( kicker 6x9's-$210) (sony splits,$329) ( 2 Kicker 4 channel amps-$700 ) and steer well clear from them in the future...

    I just read what you typed and was about to say "ahh, mate.....its aerpro" LOL.

    Just go to aerpro.com.au and go to the speaker spacers, theres two different types of pods available, but the ones i posted have a location for the tweeter (which would suit you). They come in three different colours, black, grey and carbon fibre. I would imagine a set should set you back around $60-$80.

    I find JB's prices to be quite reasonable. Depends on the store I guess.
