Hi...
I have an 05 Focus Mk2 3 door, with the standard audio system in. I'm not 100% sure whether or not it has the factory fitted subwoofer, but I don't think so. I'm looking to get a Pioneer AVH X7500 BT head unit for the car, and I'd like to get some speakers to go with it, can you give me some advice on Amps and Speakers that I'd need, and what sizes etc?

Thanks

What is your budget. That's the best place to start.

Then what are your goals of your system?

Hi, sorry it took so long to reply... I've a budget of about £200 (I'm not sure what is in $), and I want as good quality sound for that budget, and as easy fit as possible.
Thanks

200 pounds is $322 American dollars. Obviously this budget does not include the Pioneer headunit? Does it include all the parts you'll need for installation of the Pioneer? Professional labor to install the Pioneer or speakers?

$322 isn't really enough to replace the door speakers AND add a subwoofer. So best to just get some quality speakers and add the subwoofer at a later date. You have 6x8" speakers all the way around. I don't know what brands are available to you in the UK or what website ship to the UK at a reasonable rate, but, the Alpine SPR-68, Kicker 41KSC68, Infinity 682.9cf and even the Kenwood KFC-P680C plate component set is worth a look. All easy fits. Most all of those are going to put you over the $200 mark with shipping and all. If you can swing it, add in the Alpine KTP-445U amplifier to kick those new speakers into high gear. Hides up in the dash. Easy to install without having to run power wire through the firewall and to the battery. You'll be all over that $350 total mark though.

No, the budget was just for speakers, Head unit and parts are all sorted.
Ideally, I'd like to fit the speakers etc... myself, just because I kinda like that sort of thing, and professional fit may be a bit costly. I was thinking about full range speakers, and I've heard a subwoofer takes up a good bit of space, so I may leave that...

The availability here is pretty decent, amazon usually is the best, so I shouldn't worry about that.

The output of the head unit is apparently 50W 4 channel, so would that be enough for those speakers? I will have a look at those speakers though, thank you very much!

I've just had a browse at the speakers, it seems I can only find the alpines in the UK, under these model names/numbers. I will keep looking, because, like the head unit, some EU models are named differently...

The Pioneer head unit outputs 50W PEAK or MAX. All aftermarket head units output 15-20W RMS. The sound quality will be heads and shoulder better than the factory setup. But if you listen loud, then you'll want to add the amp.

And yes, some EU models have different model numbers. Donno what they are. Check out the manufacturer's UK website I suppose?

I found that amp on amazon, and it says it is 45W RMS, does this mean I'll have to be careful with the volume as to not damage the speakers?

Exactly. MAXIMUM. You need to be looking at the RMS power rating for any and all car audio equipment you buy. "Peak" or "Maximum" ratings are useless figures that are frequently inflated and deceptive, used to pull in uneducated customers.

All of the speakers I have mentioned are rated to well above 45W RMS. However you still need to ensure the gain is set properly to avoid clipping the amplifier's outputs and sending distortion (audible or not) to the speakers. Distortion is the #1 killer of speakers.

45 w RMS / 4speakers = 12.5rms per speaker.

As Firebirddude said, the built-in amps for headunits are not very powerful.

That's not to say that they cant be loud, just not quite a loud or clear as a dedicated amp.


Unless you are pushing over 50rms per speaker, you will be fine.

The Alpine amp is 45W RMS x 4 channels. That's 45W RMS per speaker. Roughly three times what the Pioneer head unit outputs.
Oh, i thought he was referring to the headunit for 45rms, not an amp. Didnt see any amp linked.

Ok, thanks, I'm not going to upgrade yet until I get my full license, because I won't really be using it until then. However, are there any gain settings or anything else which I would need to stick to ensure the speakers survive?

There are many how to's on audio sites. My advice is to find a shop that uses an oscilloscope that will set your gains on your amp for 25 or so quid.

Great, thanks very much, the final thing is, the only 6x8 Kenwood speakers I can find are these:

http://www.amazon.co.uk/Kenwood-KFC-S6894C-3-Way-Input-Enhancer/dp/B008RLCC8W/ref=sr_1_1?s=electronics&ie=UTF8&qid=1410371174&sr=1-1&keywords=kenwood+6x8

And I'm suspicious of the low price...

Would they be of good standard, or should I invest in better Pioneers like these:

http://www.amazon.co.uk/PIONEER-A6813i-Speakers-inch-Custom/dp/B00GD9BJAW/ref=sr_1_4?s=electronics&ie=UTF8&qid=1410371377&sr=1-4&keywords=pioneer+6x8

Thanks guys

Personally, I try to avoid pioneer speakers. The headunits arent bad, but the speakers and subs are usually over-rated. (ie, they claim they handle 100rms, but will blow at 90rms). I roasted 3 subs and 3 speakers before the store was willing to give me store-credit for another brand.

Take a look at polk and alpine as well, they make good stuff.
