Amp selection?

[GFXman]

I am looking at either the Soundstream - Picasso 4.480 or the Soundstream - Xstream XTA 480.4. Both are the same price so I'm a little confused as to which to get. Any suggestions?

And another question (forgive my noobiness).

Both amps can run at 60Wx4 @ 4ohms

could it be setup to run 2 channels at 4ohms (for my splits) and then bridge the other 2 into a single channel, say for a sub?

I don't know enough about how it all works so please feel free to enlighten me

It's for an SW20 MR2 in which I plan to fit some Polk Momo DB6500 splits. These have a RMS of 100W. Would the choice of amp even be suitable or should I look for something with a bit more grunt, like the next model up which handles 80W x 4.

It's all so confusing, so any help would be appreciated

[DLuded]

yes, u will be able to run the splits at 60wrms each and have 240wrms for the sub

so it will be 2x60 and 1x240

this should be enough because for every extra 100wrms of power its only about 3db. not that much when u think about it

You get what you pay for like anything these days, but when working to a budget the Jaycar range can be good. I have a 2x100w Jaycar amp that i use for my subs. Wired them up in series on a 2ohm load and i can't complain.

I got a XTA720.4 at MAS for $499 it is only running the stock fronts and a Pioneer 305c sub atm but it is incredible the difference it and the DEX P88-R + DEQ9200 make. Can't wait to get the door pods done so the Focal Utopia's can go in and then get a better sub + mono block and run the Focals semi active or fully active adding an XTA 2 channel as well.

The Picasso's are not Aust. dilivered and have no warranty here. If you look closely at the specs the XTAs seem a bit better too but they are so close I would go with the XTA to have the backing of an Aust delivered product.

The XTA amp will not disappoint despite what some audiophiles say about SoundStream's new products (not bad just not as good as they used to be).

yeah i have no doubt that the soundstream amp won't be the best around, but I'm no audiophile. I just want a half decent system that isn't cheap and nasty... im not trying to shake windows, or impress people on the footpath

At the end of the day, do what you feel is right and what suits your needs. You dont ahve to go and spend thousands on a stereo, think of what mods you can do to the car instead. A basic 4 channel amp thats say around 60-80WX4, a set of components up front and a sub if it interests u to ahve a bit of bass there as well.

My system isn't the best getting around and i did it all for under $1500.

HU: Pioneer P5750MP

Fronts: Pioneer TS-C 1655 splits

Subs: 2 MTX Thunder (with custom tube box)

Amps: 2x100W Jaycar response and a Pioneer 4x80W

I also bought all my cabeling and materials to SD my front doors and had change left as well.

SoundStream do make one of the best amps, just with a $7999rrp the Human Reign 4 1600W RMS of pure class A and they look awesome *drool* anyways. Jaycar by all accounts are excellent bang for buck.

You could always have a look around at second hand gear as I have picked up;

DEX-P88-R H/U

DEQ-9200 DSP

Focal Utopia 165W3

for well under just the cost of the Utopias everything in great nic and perfect working order. Add the XTA at 1/2 rrp and I am not doing too bad at all.

Have a lok around you never know what you may find

[GFXman]

woot, i'll head off and get one of those Human Reign amps this arvo
