can this make good power?

[EVL20V]

ok, i got a cheap sorta secondhand headunit only 40wx4 running a 300w amp and 12" 600w pioneer sub

can i add a 1000w amp and sub and still make it crank hard even with pittiful headunit?

[Lloyd]

Most headunit will be fine for any amp/sub. 40x4 will mean its probably 2V preout minimum which is fine for most amps. Give me a yell if you need help wiring/setting it up

[Monster_Magnet]

Not a problem but what brand? how many rca's? Sub out? EQ? And if it's 40x4 it could be any pre out voltage and hope it's not 2v casue thats crap and hasn't been used for around 6 years my 1999 sony wasx 3.2 with 35x4. High output levels (speakers left right front and back) are not always going to determine the pr out (rca) voltage. If don't have many pre out e.g 2v it will be quiet compared to a 4 volt pre out you see but with a 1000 watt amp it dosn't matter as any sub will have trouble keeping up with 1000 watt max even if it is at 2v pre out. How many RMS is the amp if it's 1000watts max then 250 x 2 channels RMS maybe. check RMS not MAX watts RMS means way more than max and size counts as well the bigger the amp the bigger the heat sink the cooler the main board and the cooler the transformer, Micro processor etc. i have seen amps that are 100x2 max that are 1.4 metres long and 20cm thich and 25cm deep thats huge where can you mount that in a boot aye?? well right next to the 6 subs per channel running off the beast of course.

[Caveman]

The preout voltage shouldn't make a difference on how loud it'll go, it'll only have an effect on how clean the signal will be.

I guess you could argue that a low voltage will distort at high volume but the amp will still go to max power and beyond on 2V preout or lower. Just need to adjust the gains. The fusion go as low as 0.3 input voltage.

It'll be bais as hell with a 1000W pmpo amp and 35Wx2 pmpo at the front lol oh well I drove around for 6months like that too

[blackie]

2V hasnt been used for 6 years.. ?
no way, most low-mid range units still use it today..

And yes, it will be fine. We went down to dunners in our undie car with an oldschool alpine 25x4 single preout unit, and an old power acoustik amp, and it cranked our sub hard as

[Blackrazor]

Higher preout voltage = better noise rejection. It has nothing at all to do with how loud it goes. With the right amp, a 0.5v preout headunit would crank hard

[Lloyd]

In any case its not really going to matter as this isn't exactly a competition class stereo system and its for a sub anyway

The man speaks truth.

[Monster_Magnet]

Yes he speaks the truth but still Blackrazor should buy an rca splitter and try and prove if you splice the preout signal into two using an rca splitter that it isn't quieter. Im sorry but I tried that when i had one set of pre outs and what happend I regesterd a 37.2 Db drop frm splitting it and running an extra sub as opposed to running one thats stupid difference all new gear. Pre out voltage the higher it gets the stronger the signal the louder it gets simple its like turning the gain up on a head unit with sub out control when you turn the gain up the volts go up hence the volume goes up *simple*

[Lloyd]

Splitters dont make it quieter. All that will cause to happen is higher current draw along the RCA cable, the voltage wont change at the end of the RCAs. Run one wire off your battery and you'll have 12V at the end of it. Split it from one into two and you'll still have 12V at each of them

By the way, learn to use punctuation Monster_Magnet. Half of what you said made no sense at all.

[Monster_Magnet]

Hahaha trying to take the piss out of my punctuation is lame but whats even more lame is the fact you who trys to put me down about stereos has just compared Watts to Volts to different measurements on to different scales and shall we bring ohms into this conversation.

It's this simple I install my own gear have done for years that dosn't make me a guru but how many sound offs have you won buddy after you installed all your own gear?.

I was the 1 - 600 watt open class winner for 3 years in a row for the whole of the south island total 7 wins in first place and 3 in second place.

Done with 2 Ten inch Sony's a 400 watt amp 6inch components with tweeters and cross overs and 6.5inch pioneers if you have a record like that then I will listen to you other wise why should I was that a competition class stereo huh?.

On a more important note did the guy who originally posted this thread get his 1000 watt amp??

[Lloyd]

I dont recall even mentioning watts in that last post. And I wasn't putting you down about punctuation, just suggesting that you might use it as it helps people understand what you're saying a little easier.

Personally I couldn't care less what you're won or installed yourself. I've seen plenty of people who have installed their own stuff and have spent a bit of time having to fix up what they've done wrong. I haven't won any competitions as I haven't actually entered any and dont intend to as I dont need to go and show off what I've done. And people who know me and what stereo setup I have will tell you that its not exactly quiet for what it is.

And as I said above, splitters will not make the signal quieter as the voltage at either of the RCAs will remain the same whether you split them of not. The current draw alond the RCAs will be increased. Wattage has nothing at all to do with the RCAs basically

Guess you musnt have had very stiff competition then huh?

Heres a bet for you Mr MonsterMagnet, Ruler of Past Soundoffs and System Designer Extraordinaire : Come along to the next SQNZ Sound Quality competition in the Christchurch area, there will be one held before years end no doubt. Enter Amateur class, i wont even make you go in Pro. And if you can even place 3rd, not even 2nd or 1st, i will not only hand you $50 cash, i will buy you a 12-pack of beer of your choice to boot. If, on the other hand, you do not, you must come on here and say you got your ass handed to you on a plate by the bunch of rank amateurs that you seem to think we are.

Deal? You gotta agree to that one, since you're so confident in your ability, right? I mean, you talk the talk, i guess you can walk the walk too?

Nah, no spare time, i just took two weeks annual leave recently coz its the only time i'll have a chance for more than a day off at a time till mid next year

If he's as good as he thinks he is (which IMHO he isn't) then he's f**king mad not to take that challenge up.

<the wind whistles quietly... a tumbleweed rolls along>

No response? What a SUR-prise...

[Monster_Magnet]

Hahaha ok so people are getting up tight what do you want me to say what will make you feel better you all seem to be having a dummy spit over the whole thing.

I won a competition and now every one is spewing sounds like sour grapes??

Did anybody compete against me in the south island???

Hello any body???

Hang on:

<the wind whistles quietly... a tumbleweed rolls along>

No response? What a SUR-prise...

Hey an just cause you wired up your sub and amp from the warehouse by your self dosn't make you an amatuer it makes you good at reading intructions.

[Monster_Magnet]

dude and if the first comp u entered into was run by SQNZ then you havn't been doing this long have you.

Before that was CANZ running under IASCA rules which were international not national.

Alot harder judging

Wiring
Fusing
Freq.
Static Freq
Sign Generation
Bass Distortion
Tweeter Testing
Headunit Output
Volume of space behind each sub
Volume of air in car
Angle of subs
Angle of tweater
Alternator Amperage

Have you checked to see if your fuse holder is less than 10 inchs from your battery do you have it mounted do you run grounded RCA's or not.

Now you try and win with those conditions
