Hey guys,
im finally gonna install my new system this weeknd, just wondering what you guys think of it and if i should make any improvements and before you start i basically got all of this lower than cost price or free off mates that i have done favours for in the past
Head unit is a JVC KD-g615 going to buy this brand new this weeknd for about $250 or $280 installed.
Front splits are the basic kicker ones that retail for $230 i think the model number is kx 60 i think, got them for free off a mate and will prob end upgrading these later when i get some spare cash
Rear Speakers as some 320W competition pioneer 6*9 (had these in my old car and they go harder than a 17 yr old on viagra lol) model number is something ts-190 or something
Amp is a 700W boss audio amp, about 2 yrs old, 4 channel got it off a mate very cheap so should do the job
Sub is a 600 pioneer one of those silver bullet ones, goes pretty hard as i had 2 of them in my old car but only used one after i kept taking one out for trips


ok i will prob run the splits off the headunit unless someone tells me otherwise as i think they have a low rms rating.

the rear speakers and sub i will run off the amp bridging 2 of the channels for the sub.

and i think thats about all, any help would be great as i have done lots of car audio installs but not that good with the finer tunning of audio gear.

cheers

BUMP
where are all you audio know it alls gone? :nuts:

Yeah Yeah yeah... I also have a full time job geeze... ;)

OK forget amping ur 6x9's. it is irrelevent if these have a power handling of 1000w you still want your soundstage in front of you so u should put most emphasis onto the fronts.

I say, amp your fronts, bridge the other two channels for your sub, Run the rears of the headunit.

Front speakers should be the primary part of any system.
Rear fill should be exactly that.

Peace

thanks for help anyways ill be scouting the forums for a cheap 4 channel amp to bridge off the other one, whats the best way to do this so i can have it set up right
cheers

Trust me the JVC KDG615 has more then enough power straight off the Deck to run your Fronts and rears without the need for an Amp...
All you would need to do is Amp up the Sub and use the Sub controll off the Deck to blend your Fronts and Rears in with the sub..

The Only advantage I can see of amping the Fronts and rears is if you want to get a Amp with variable Crossover to give you more sound control..

The KDG615 has more then enough Oomph to send you deaf without the use of an External amp for your Interior Speakers...

The KD G 615 has an Internal Amp Switch from low power to High Power mode.
In Low Power mode it goes to Volume Level 30 and in High Power mode it goes to 50...
By Volume 21 my Speakers are in Full Song and sound great..I can Run it at 30 without Distortion..
I keep mine in Low Power mode so I can crank it up full and not worry about Distortion comming in.

Boss Audio Amp will be Good enough to run your subs but they tend to have noise porblems and can lead to a ruined Front stage..
If Your Pioneers are the Yellow coned TSD's then you will benefit from amping them as the really do need some power behind them to sound good..

Just remember to keep your Front stage amped a little higher then your Rears Just enough so they are not distorting..

Definately amp ur front speakers. And there's definately a big difference with regard to if u run it of ur headunit or amp. Yeah, amps are good coz they have x-overs and big power ratings. esp good for when u wanna turn it up loud.

if u get spare cash, sell the amp and get a good one:P

i cbf replying properly these days:doubt:

EEk, the JVC KDG has 19W RMS x 4 on tap... this is just as powerfull as the the Cheap 200W amps you can buy...

so does my jvc h/u...but it sounded so much better when i had them up to connected up to my PG amp.....but yer...its a cheap 200w amp.

did u...u didn't edit ur previous post did u? or am i seeing things:nuts::confused::shock:

you have Pm 97_verada

Ok 19 w rms, is piddly sqwat. Will be fine if u dont like ur music loud, but I can no longer appreciate any music that comes out of a headunit. Once you amp them u will appreciate the difference.

Most aftermarket speakers can handle beyond 100 w rms. Ignore the power ratings on your 6x9's. Just because you can drive them at xxx watts doesnt mean you have to. The fact that they distort off the headunit is because the headunit is struggling to provide the clean power and is clipping the signal when pushed beyond it's means.

I have ~800 w rms for my fronts at my disposal. You need headroom to get good quality sound.

But seriously, don't bother amping your rears, there is no reason to have all the sound coming from behind you. You will get much better sound quality by putting in the time and money into a good front stage. MDF baffles, deadening etc.

If you hadnt already bought rears I would say keep them stock and put all ur money into front speakers.

The rears are only there for bass and fill in a stock system with no sub. They use the boot as their enclosure. Yes they are practical for stock systems, but as soon as you get a sub they serve little purpose. They drag your soundstage backwards.

Amping your fronts will make it sound like music is coming from all around you anyway. Try it out and see if I'm wrong. You will see remarkable midbass, compared to the rear 6x9's. Speakers are meant to be round.

Do you go to a concert with your back to the stage?

yeh it all sounds right, i think ill get another amp for the fronts and still run the rears off the rear amp but turn it down. Just wanna have the option there to have bass fix if i feel the need.

How do i run 2 separate 4 channel amps properly so that ill have 5 or 6 channels available?

cheers

Bridge 2 channels to run the sub. Run the rears off the other two channels. Then if you have another 4 channel amp you can run the fronts by bridging each channel. Then you'll have heaps of power at ur fingertips.

does that mean i run 2 separate controller wires from the headunit to each amp

a simple diagram would be great if possible

If you have sub out and front/rear rca out from ur headunit you will need to run three sets of rca's.

Front rca to one amp.
Rear RCA's to channel 1+2 of the second amp
Sub RCA's to channel 3+4 of the second amp.

Depending on what kind of power you have though as to which amp will be most suitable.

I would suggest buying a monoblock for your sub(s). Then Running the speakers off the 4 channel.
In which case
Front RCA to channel 1+2 of 4 channel
Rear rca to channel 3 +4 of 4 channel
Sub RCA to monoblock

Each amp will need remote lead from headunit (can daisy chain this.) Ground, Power, speaker wires etc

The monoblock would be an optimal situation anyway.

the 2 chanel blakpaunt 220W amp thats FS on here should be ok for this shouldnt it, as i dont have much spare cash at the moment and i should be able to pick it up cheap
cheers

i've recently experience the crappiness of 6x9s in my setup. im looking at a rework... it def will include 6.5 splits in the front off the amp... and the sub/s in the back what happens after that fate will decide.

the 2 channel Blaupunkt 220W amp thats FS on here should be ok for this shouldn't it, as i dont have much spare cash at the moment and i should be able to pick it up cheap

Just had a look, looks all good. it's new, so u shouldnt have too many problems. $100 is a reasonable price too.

It's not top of the line obviously, but 40 w rms will give you some big improvements. The Blau is prob better quality than the Boss so would be suited to the fronts despite the lower output.

heheh, prob

but ill bet you that itll be in before the end of may as i have most of the gear sitting in my room just have to get around to installing it all, might make a start this weeknd on moddifying the parcel shelf to fit the oversized 6 * 9's in there and go from there
thanks for the advice ill let ya know if it helps

over sized 6x9s dont they fit under the standard covers???

over sized 6x9s dont they fit under the standard covers???

nup not the yellow coned pionner ones they sit too high and the bracket is too bit for the holes in the parcel shelf

will get the pliers or grinder to it this weeknd and let ya know how it all goes

jaz

sounds nasty... i've got some 3way pioneer 6x9s nothing special at all... the right one sits flush and the cover goes on.. but the left one doesnt :(... damn eurovox :doubt:

but yes let us know how all goes :)

pacel shelf slightly modified along with with stock speaker grills and the rear speakers are in.

Any ideas on how to run the wire for my front speakers from the door to the main body of the car, seems to hard to get them where the stock wires go.

Try try and try again. Undo the loom from both ends, pops out fairly easily, then just ram those wires up and twist, shake, bend and do whatever you can to get the wire up.

Once uv got the wiring through to the kickpanel you can get a little brother to reach up and grab it, or hook it with a coathanger.

Will get frustrating, but it is do-able.
