Quickie Amp and Sub question.

[PhatAshKi]

I got two db audio subs, Cost me a small fortune while back and dont wanna get rid cause they sounded great in my old car.

Now im not bothered if i need a 2 channel amp or a mono one (Was wired up in a mono in series in last car and worked fine) Just wanna get the best out of em.

Question is, The subs are 375w rms and 750w max,

Now am i right in thinking that if i get a 2 channel amp (1200max) 2x600w max and 2x 240w rms, will the amp be running over time or would that all sound about correct and not damage anything.

If its not powerfull enough and run ova time any suggestions. Obviously dont wanna blow subs.

Cheers

really you want like a 2x400wrms amp

 

[PhatAshKi]

I know ideally, but that is getting mega expensive. Just asking really would the amp and subs cope with that rms or would i really have to get a bigger amp such as about 350rms and save a little longer.

 

[PhatAshKi]

Well the amp i was looking to buy was this blaupunkt one

As long as you're careful, a weaker amp will do for now, and then you can upgrade when you can afford it

Is £160 your budget?

£10 of that says I can find a better used one on eBay.

i nearly bought that amp then realised it was too long even if it is slim I bought the kenwood one instead. mono amp with i think 900watts rms

get 2 2x channels for less than one 4 channel

think its the same??

You probably could as well

 

[PhatAshKi]

Well not really my budget, i can go more, Prob £200 Was just wondering if it would do. Id rather buy the right one first time than having to waste money and time buying and installing another.

So basically ya saying that in time that would be working ova time and damage?

Anyone suggest a decent amp with about 350rms and about 750max, Even if mono i could just get two.

Wen you mean carefull chaos, wat exactly do ya mean. Would be easier if i just had the one sub then just buy the right mono amp. They only 10" but have decent sound and dont wanna get rid.

 

[PhatAshKi]

No body have any suggestions of amps, Been looking on ebay not quite sure.

How carefull should I be wit the amp above as a might just get that. My amp before was only 1000 max and 200 rms between em and worked fine.

Sorry I haven't replied earlier Ash

By careful I mean not clipping the amp and distorting it.

Get a mono amp with about 800WRMS at whatever impedance you need (dependent on the voice coil config of your subs), or if there's one to suit, then a 2 channel job that would do 800WRMS bridged. However, I think you'd be looking at second hand (but that's not a problem )

No problem dude.

How would i clip it, or more to the point prevent it.

And if i was to get an 800wrms or close enough amp (in 2 ohms) with it being mono would i wire them up in series or paralell to share out the 800rms, Cant remember from school but i think it would need to be in series altho correct me if im wrong. There were in series before wit a my last amp but that had a puny wrms. Only 1000 peak

I say 2 ohms above altho on the site of makers of my sub they say Nom. Impedance 2 x 4 ohm, I assume is mean 2 to 4 cause y would 1 sub need 2 x 4ohms, Unless it means 8!

Remember max watt is 750 to

Wat bout this amp, Seems to cheap tho! Cheapo make??

Max wattages mean naff all - not worth reading about. I reckon you have dual voice coil subs there (2 4ohm coils )

There's 2 different scerarios available to you

1 - running both subs off a single mono amp and presenting either a 1 or 4 ohm load to the amp.

2 - running each sub on an individual amp - this way each sub would be wired to show either a 2 or 8 ohm load.

So what you want is either.................

1 - a mono amp that will do 800WRMS @ either 1 or 4 ohm

2 - 2 separate mono amps that do 400WRMS @ 2 ohm each (you won't be running at 8 ohm loads in this set up).

Personally, I would go for option 1

Link might help lol http://cgi.ebay.co.uk/1600W-AMP-4-CHANNEL-CAR-AMPLIFIER-SILVERSONIC-ALUMINUM_W0QQitemZ260023373731QQihZ016QQcategoryZ4950QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

This anygood?

 

[PhatAshKi]

Right thx choas, Ill have a look for a mono amp with 800wrms, Even wit 2000 max watts that be ok for the subs?

Latsly wit the mono amp i take IT WILL have to be wired in series?

Cheers for ya help fella

Series for 1 ohm, parallel for 4 ohm IIRC.

Like I said, totally ignore max wattages. They mean nothing

 

[PhatAshKi]

Thankyou very much, Ur a star. Ill let ya know how i get one
