TV touch screen ?

Re: TV touch screen ?

James, there is no wrong system.

An all focal will be a great system, if you don't mind that sub then that's a good one just check the dimensions are ok with your boot, my smart is my second car so I never depend on the boot for carrying things.

I think it's better to put the amp behind the passenger seat rather than underneath the seat, it allows you to adjust easily after it's put in. And with that get a regular focal 4ch amp, will probably be around the same price.

Just to confuse you more that sub is in a ported box which means it has a vent(hole in your term) this means it can play deeper bass as the port allows the sub to move more air thus creating more powerful bass. This is a way of having a smaller box with more output. There are cons but nothing you need to worry about.

I'm quite enjoying this thread, I don't post a lot but it's a topic I love

Re: TV touch screen ?

@Cougar- many thanks for this added information this is mainly what I don't want to do is buy a load of equipment then be told the amp is not powerful enough so ya won't get the best out of the sub or it's way too powerful and then I could of got a lot better sub etc I do want to try get a all round equal system. Just that sound systems and watts rms and all the other bits are defo not my strong point !

Think I'll just write down all the whole system I'm thinking of getting and see if people can tell if it will be ok and work ! ?

Re: TV touch screen ?

Watts is the measurement of Power. 250W RMS is 250W Root Mean Square, its fairly complex to explain but essentially it means that that it is the power at which the Sub will work at normally, the max Wattage is 800W this means that peak power it can reach is 800W however you should not buy an amp over the RMS value in order to avoid damaging the sub. So buying an Amp with an RMS value the same as the sub is the best way.

The Sub can get up to 800W pumped into it but it is likely to destroy itself if held at that power for any amount of time. There are a few measurements for power, nominal, PMPO, RMS and MAX. PMPO is Peak Music Power Output. RMS is Root Mean Square and Max is another way of saying PMPO. Ive never liked things that advertise the PMPO because they give a false sense of the true power sustainable by the piece of equipment. The only value you need be interested in is the RMS value. That reflects the amount of power in true terms.

There was a big thing back in the 90s where things were advertised with huge Power ratings that made people think they were buying something really powerful. I never liked this because the true RMS of those pieces of equipment was much much lower than the advertised power output. Different pieces of equipment deliver different RMS values even though they may have the same MAX or PMPO value. You willl never really use a piece of equipment at its max power and if you do then you are likely to need to buy a new one!

This is before you get to the type of amplification, not all amps are the same, they will use different types of Amplification. The best being class A and the normal being class B these classes are based upon the way in which the signal is amplified. However its almost impossible to find an amp with class A only, that has a lot of power. Most amps use a combination of class A and class B amplification some even use class C.... The Higher the class the better the quality generally. So A being the highest means it would have more definition to the sound. Sound quality depends on the circuitry design and the quality of the components used in the manufacturing of the amp. Its all a personal preference and some prefer some amps over others because they hear the best part of the sound that suits them however others will think differently. I would stick with a good branded Amp they may be more expensive but you pay for what you get.

Re: TV touch screen ?

@adrimo thanks for the break down I'm not gonna lie thou baffled comes to mind ! Well I'm looking at getting this

Even thou I like the look of the JL sub ! Just a thing I like to have all the same brand (OCD I think) lol

Good idea with making tem plates hopefully wanting to mount the amp behind the passagers seat, or underneath it not 100% sure yet but that's after iv worked out what I need to get etc ! Yeah I do like that amp so is it "best" to bridge for a sub or like this one getting a 3channel ok/better ?

@problemchild- yeah I think it just give me few more options with it all being separate that's all and don't think I will need to add any rear speakers even thou I watched a video on that the other day,but think good enough tweeters,mids and sub will be plenty !

Oh and thanks for showing me that pioneer double din---- 😠😖 I want I want I want now and the wife says.......... Dream on lol got some buttering up to do

Re: TV touch screen ?

adrimo - an active sub is just an enlcosure with a dedicated amp attached to the enclosure.

think you are thinking of bass tubes or the slimline active ones.

James - if you going to get an amp anyway then you may not need an active sub BUT if you decide to add some rear speakers at some point then you will need another amp to power that. From what i have seen, active subs are not much more than passive.

Re: TV touch screen ?

I mean the sub needs to match those 2 features

Let's say you go for a sub by jl like this one

http://www.ebay.co.uk/itm/JL-AUDIO-WXv2-10-inch-Subwoofer-Driver-200-W-4-10WXV2-/281228604931

It works in boxes from 0.65cuft to about 1.2cuft, at 0.65 it will play tight bass with a good response and it will take quite a bit of power, if you used a bigger box generally it will play a little deeper on the bass notes. I have always had small cars except my golf so always gone for about 0.6cuft making boxes is very simple and allows you to match to your car.

I had the sub above a few years ago well it's pre-deceasor anyway and it was excellent.

Or you can look at the link below

http://www.caraudiodirect.co.uk/jl-audio-cs110-wxv2-basswedge

This is a complete sub and box designed and made by JL, I have used this company many times and recommend them highly you can even call them and ask them everything you want and they will help.

How about this amp very good price also

http://www.caraudiodirect.co.uk/jbl-gto-3ez-3-channel-amplifier

2 channels for the front and the 3rd for the sub.

What I always do is grab a cardboard box and cut out in the size of the amp and box and use to see where in the car it will go and if it's right.

Re: TV touch screen ?

Always match watt rms figures forget about max output, look at Jl audio, focal, hertz, alpine, orion but mainly look for a sub that meets

1 power of amp
2 size of box

You probably want a 10 inch sub that can go in 0.5 cubic foot sealed box

Oh man so sorry but that's just confusing talk to me :-/ so look for a 10" sealed sub any of the following makes -Jl audio, focal, hertz, alpine, orion not sure what you mean on 1 power of amp 2 size of box ?

Re: TV touch screen ?

Sorry to sound like a broken record but how do I no if a sub is the correct watts and rms ? I'm looking at getting this

I'm so lost then what amp preferences should I look for other than a 4 channel amp

Re: TV touch screen ?

You run the crossovers off the front outputs then a tweeter and a mid is connected to each crossover.

Oh ok so the crossovers act a like a splitter box yeah ok that's cool then thanks MD ;-)

Yeah now this is nice and have to save the pennies before buying this but yeah pretty much spot on what I'm after HU wise.

Adrimo:

that was very heplful thank you ever so much for the input so how do I and where do I run the tweeters off. Mids and tweeters together in the 2 channels and in the other 2channel bridge them and power the 10"sub off it ?

I also just want to say thanks to all who have have me some advice and that it's all different for all people different set ups might and will work better for different people I'm sure I will figure out what mine is but you all have got me thinking of all sorts but iv have decide--

Pioneer double din HU like the one problemchild mentioned

Focal 165 door speakers and tweeters

4channel amp (not sure on make yet)

And a 10" sub also not sure on make yet maybe focal or fli see how the funding is would like all to be same make focal

Re: TV touch screen ?

Yeah I make you right there not many places to put it really ok well least this is deciding thing for me so 4 channel amp under the or behind seat !

On another note what's the difference between a mono amp normal amp ? And a active sub and a normal one ? And how will I no what one to get ? Sorry for all the questions I really no bugger all about the audio systems lol well least I sorted the mids and tweeters now,now all I need is a amp 4channel normal or a (mono) and a sub or (active sub) oh and a pioneer HU iv decided pioneer ! Not sure what model yet thou ! Slowly getting there thou then to fit it all ahhhhhh lol :-/

Mono amp is 1 channel and used to power a sub/multiple subs.

Get the head unit you want with all the features u want first, that way u don't need to change it as it's what u want and has the features u need. You have your components which are very good IMO and will sound better the more you use them.

Buy a 4ch amp, why, because that will make your components sound the best they can and give them the power they were designed to take, you don't have to but when u turn up the head unit too loud it will cause distortion and speakers don't like distortion, it will shorten your speaker life.
The front 2 ch will power your components and the rear ch bridged will power a sub.
Now the advantage of having a separate amp is that it will be more flexible, flexible means that if you decide to change your sub for what ever reason it's simple, if you decide to change your amp again it's simple plug in and swap, if you go for an active sub it means 1 you may pay more but if you change your mind or it breaks there is more involved.

The thing about having a proper sub over and active sub is that again you get more, my advice is loose a bit of boot like mine which has not impacted me as all. You can get a shallow mount sub which will take up about 2shoe boxes and sound better than an active sub, why because generally it will be a larger diameter ie 10/12 inch and it will have more volume of air to move, more air equals deeper bass generally. Even if you go for an 8inch sub in the boot it will sound better than the active sub route.

It's all subjective and about opinions I give you advice based on fitting many systems in many cars but I'm in no way an expert, but as the smart has less sound deadening and plastic body panels IMO it makes having a better quality system even more important as to over come the outside noise you have to turn up the volume.

At first I had an amp which was 4x20w rms and the sound was good but something was missing and when I turned up the volume the front mids would make the dash vibrate so I took some of the lower frequencies out, I then changed my amp and now I think it's 4x75w rms and the change was instant I now don't need anywhere near the volume before and I can even have the sub off and still get good range, so I add a bit of sub and it gives me good all round quality and I don't need to drive the speakers as hard, also no vibration from the front even though they get more lower frequencies than before.

I hope this helps you find what u are looking for and helps you understand why I give you my advice. A well bought system will last you many years and you find you can move it from car to car.

Re: TV touch screen ?

a sub is a speaker for deep bass.....

a normal sub needs an amp to power it...

an active sub has an amp built in.

if you buy a 4ch amp then you CAN run the sub from that as you only need 2chs really (left front, right front) .... and if i remember, you bridge the other 2 channels to give a sub output)

not sure how common 2ch amps are though.

seriously, my advice is get a boxed active sub as the slim line ones just aren't gonna be what you are after (been there done that)

don't get an amp yet. fit the speakers to the new HU and see if you want more power. its not about LOUD its more about not having the volume of the HU 90% to get good volume.

save your money for the HU - thats the bit you will notice.
