I also have a set of boston acoustics pro60 component speakers.

I am looking at getting some soundstream amps to power this. a TRX700D (for the sub )as well as a a TRX 2.550. Basically just wondering if these are suitable or overkill/crap/cheap n nasty..... ANy alternatives that you could get for a similar price would also be appreciated.



Sorry for the large pasting of tables

Given the soundstreams price and specs there is nothing wrong with them,

they are made alongside Rockfords, power accoustics and various other amps in the same factorys. Obviously they are not the same amps. but the quality and sound is extremely good given the cost.

If your in the budget SQ amp range I'd say they are definatly worth considering.

I'd actually personally take these over something like a Alpine PDX for my main speakers at least. This being said i'd take soundstreams older school amps before buying the newer ones though. but it's the same to be said for just about any brand.

Kind regards
Juls

Is that $750 max for each amp, or $750 total for two amps?

You can look into the Audison SRx range no amp over $750 in that series including a 1150w @ 1ohm monoblock. These amp have a very good rep in sound quality so give them a look

ever heard a brand called consonance engineering? it should be below your budget (AUD650)... it gives you 4x100watts for 4 channels amplifier and 2x150watts for 2 channels amplifier... you can contact OZBliss Enterprise (Melbourne) regarding that particular items... It runs 3rd place on the round 4 expert class VIC MEASQ...

just curious, why soundstream? any particular reasons?

LUKE352.. Looking at $750 max to run whole system


RE: why soundstream? just saw some nice looking soundstream amps so was heading down that track, but if I can find something that is int the price range, looks good and performs well, there is nothing stopping me from going to a different brand..

Thanks for the info guys. Will look into the options stated above.

Please be aware that due to the dollar hitting a record low of 0.66 USD (a drop of 22.35% over recent weeks) all prices for car audio are more than likely to rise significantly!

But remember - shipping it also cost a lot more and that will mean a bigger increase.

Indeed.

The Aussie dollar is BRUTAL at the moment.

Guys remember that unless you are buying from overseas, the place you are buying from locally will not be hit with massive price increases that you will have to pass onto their customers. Orders from international suppliers are made months ahead of when they get the goods so therefore we wont see the price hikes in oz for a wile if at all.

W R O N G !

Yes orders are made in advance - ALMOST 99% IF NOT ALL ORDERS ARE IN IN USD or EURO which just went through the floor!
So when you pay for the stock it is in USD or Euro and at the exchange rate of the day.
Very few companies are investing in futures which is how you lock in a rate.

So when you look at products like Hertz, Audison, Morel, DLS, Rockford, SoundStream, Dyn, Tru Tech. Arc, etc etc etc
all the "boutique" brands, well I would bank on a price rise. (I do not for one second speak for these brands I am just generally speaking)

I just had $50k USD worth arrive on Friday
That shipment was budgeted at around $59k + 4k Freight charges = $63k AUD LANDED COST

That shipment is NOW more likely to end up costing $80k + $4.8k = $84.8k AUD LANDED COST

For those that can't work it out - That is a 33% increase on landed cost.

With the dollar fluctuating wildly between 62 and 70 Aussie cents to the USD there will be an increase somewhere in the region of 21% to 37% depending on where the dollar lands and how much manufacturers and distributors can absorb.

Best case scenario 15% - 25% will be passed on.

The severity will depend on margins and where the last calculations were made, for example if as a wholesaler you made your last wholesale calculations based at say 70 cents to the USD (most would have made it at around 85 - 90 cents given the strength of the Aussie dollar of late) you would be in a position to hold your price, however if you were costring at say 80 or above, well you will have no option but to have an increase.

Most manufacturers do offer some terms ie. 30 account or 60 day account from invoice / shipping which we pray will be long enough for the dollar to move up a little before we have to pay the invoices, but as someone who has been through this before I know the best we can expect is maybe it will hit the 69 - 70 cent region.

Most wholesalers would at this time be consulting their crystal balls like crazy to make an educated guess at what point the dollar will land between where it was, and where it fell to.

Some of the really larger player "might" have a small degree of forward purchase protection but on the whole PRICES ARE RISING!

But don't take my word for it, ask any retailer and they will tell you last week their fax machines were nearly melting with the volume of faxes coming which were new price lists announcing price rises.

Prices are going up !

When the Aud rose against the USD you put your prices up, saying something along the lines of more expensive parts needed or something along those lines, and because the USD was "low", the amps were more expensive (and speakers).

Now the opposite is happening, your prices are still going up

.....

Sure I love jacking prices up why wouldn't I - it makes so much sense.

1. It make our products just that little bit less attractive to those that love to whine (not pointing any fingers)
2. I sell less stock and therefore make less money, isn't it the goal of every business - to go broke that is?
   
   You either understand or dont understand economics in your case it seems to be the latter.

As far as raddeal and his remarks go, how I could I him take serious? raddeal just seems to be someone more interested in stirring up trouble than ever saying an intelligent word.

I've said my 2 cents thats it, I have nothing further to say on this matter.

Foot note:
SRx 3 and HSK165 both of which have not changed in price since July 2007.

No need to explain ecnomics to someone who clearly understands them.

Interesting how most other companies didnt rise their prices when the AUD was strong against the greenback, also interesting to see how DLS droped their prices a fair amount a few months ago.

People will start to buy less of your products my good sir. Fortunality this wont affect me, as we have spoke aboue my love for RMA's products in the past

Have a nice night

Have to agree with that...

Try hedging your orders Phil, lots of ways to do it.

hey guys - that's enough phil-bashing, I understand that when the dollar is bad, we pay more - get used to it, get over it.
As for Hedging , the business I work for hedged at .80 about 6 months ago, no need to change it just yet, get off the swing and go play on the roundabout for a while.

This is a SQ discussion (IIRC) so please keep it to that.

In SQ terms, most 'reasonable price' amps are ok. I wouldn't spend less than $700 or so for a monoblock or 4-channel, unless I knew it was a good'un.
i.e.
Audison 'LRx',
JL Audio 'Slash'
Eclipse 'XA'

just a few

Prices etc are always going to be a hot topic, BUT
not really on topic anymore guys.....?
origonal Question relates to types of amp to rus a SQ system...

How do the audiosystem amps stack up for SQ? I've heard some good things...

I have spoken with Comsec & FOREX re Hedging and it is not possible at this stage, and Hedging can work for you or against you also.

If you compare products such as RF against LRx we are still offering better value for money in 99% of cases when you compare like product.

Anyway its happened and lets get on with it rather than getting bogged down in it.

Very nice amps, i had one in my car for a while and was quite impressed with it's performance! definatly recomend them!

How do they sound? Warm, bright, sharp with raw power? Trying to compare this to a JL Audio Slash series amp (which I have heard and loved the sound of).

it's been some time, but i found them warmish and easy to listen to. i think at the time i swaped it out for my SS reference which is my benchmark for amps and it faired quite well.

personally i would take it over the slash amps but i never have been a big fan of the JL's

Try a natural hedge rather than something exotic (such as simply converting AUD to USD at the time of the transaction to lock in the rate). That way your landed cost will remain at what ever you converted at (bar any other transaction costs).

Also Phil hedging doesn't work for or against, it simply locks in what ever the rate is and gives you certainty against any movements.

If prices for the audison Srx 3 havent changed how much are you asking for them ?? just curious.

I know its off topic again but thought id just share that when speaking to Stylin Car Audio in Melbourne today I was warned to buy quick because pretty much ALL of their suppliers were putting on a 15 - 30% increase in price. They said there would be a 15-30% increase in price to almost all products in the store as of either this comming Monday or the Monday after - i forget.
