amp help

[rk has a vn]

Ok I want to run a set of 4 inch 150 watts, set of 6 inch with tweeters 220 watts, set of 6 inch 300 watts and set of 6x9 500 watts.
What sort/power amp will i need??

The size of the amp won't really matter. You can just tune it to cope with your speaker load. so say a 1000w amp for example, you'd be afraid of blowing your speakers. Well yes you will if you run it on full gain, but tuning it will prevent this. A very basic idea of tuning is to just turn your headunit to about 75% volume, with your amp on 0 gain, then slowly turn up the gain until you hear it to distort, then back off to a bit before distortion.

Many, many options, depending on your budget and how many amps you wanna run. I'd just go two 4ch amps though. Simplest way of doing it I reckon.

Waste of time with 4 inch. By the way what is the RMS not peak power.

[rk has a vn]

Yeah now I'm confused

[DUK13Y]

Which part?

[rk has a vn]

U say 2 4inches he said there a waist of time

I am saying the 4 inch speakers you have are not worth amplifying. What DUK13Y is saying is get two 4 channel amplifiers to power the other speakers. Curiosity has the better of me I'm afraid. Why do you need so many speakers?

I Like loud noises

Where are you putting all that? The other speakers (>4" speakers) will probably 'cancel' any sound you are getting from the 4" speakers. No one here can really provide accurate help unless you post up the brand / model number of your speakers, that way we can find out what the speakers are and what sort of proper (RMS = Root Mean Square) power they would like.

Instead of wasting your money on 4 sets of cheap speakers, why not get one really good set? I run one set of 6" splits and a sub and it's more then enough to make you deaf.

By the way, if your speakers can actually handle the power ratings they say they will, i will eat my own hair. Cheap speakers usually have optimistic maximum/peak ratings rather then a proper average (rms) rating. Most decent 6" speakers won't handle much more then 100WattRMS, let alone cheap ones.
General rule of thumb, if they claim handle more watts then they cost in $, they are telling lies.

I have a decent 10" sub in my car with a very large motor/magnet, probably weighs at least 15kg, and it is rated at 'only' 375WattRMS.

Quality over quantity when it comes to car stereos.

I agree in terms of not having so many speakers to get noise. Unless they are good brands of course. I had a cheap set for my old Lancer to put in the back cause you couldnt hear anything in the back without the front cranked up and that was just unpleasant cause you then couldnt talk to anyone, etc. However, the cheapo speakers were simply for fill and nothing more. I was not going for quality which was good, because they sucked. Good just to get some music in the back, but sound was very low quality.

If you're after good sounding loudness, get yourself a decent set of front splits like Alpine, Pioneer, Sony, etc, buy a set of decent door speakers for the rear (I prefer having the car the same brand throughout) and run them off a 4ch amp, tuning front and rear independently. Then get yourself a 10-12" sub and power it off either a 2ch bridgeable amp or a monoblock amp. This set up is much more practical and will certainly be loud enough, but should also be good quality sound. Just stay away from cheap brands and you should be ok.
