Amp question

[eskimo]

I scored a Sony xplode 222w amp for free and have a set of XS-GTF6935B 6x9 3 way speakers that are currently run off the head unit but I want to change them to run off this amp

Will this amp be fine for just these speakers, i.e. not under/over powered etc?? im a complete newbe when it comes to working out this jaz so not sure how to work out whats needed

The rated input power for the 6x9's is 60w and max output is 300w

Cheers

It'll be fine

Just turn the input down when you first crank them up and then raise it until they give the desired effect.

I think those 222 amps are only circa 35RMS per channel so you should be safe as houses provided you dont go boosting the bass signals too much.

222 should be slightly better (clarity and bass) than powering from a 52x4 head unit.

Anyhow, you wanna direct most of your bass away from the speakers and towards your sub if you have one

if its 2 ohm stable you could bridge the amp and run the speakers that way to gain a little more power. but i cant remember if they are. heat could unsolder connections. correct me if im wrong.

[gt4dude]

the 222 is only a 2ch amp, you must be thinking of the 444 which I don't think is 2 ohm stable.

the 222 is good for head units which only have rear rca and sub rca but no front. you'd power your rear 6x9's with a 222 amp which would be better than powering them from the headunit's powered rear output.

alternately if you had a 6channel rca head unit you'd run a 444 for front and rear speakers, with a separate larger amp for the sub.

you can run the two speakers bridged on a 2ch at 2 ohm like you do with 2 subs. but some older units heat up alot doing this

[gt4dude]

ahh i see what you're doing here, but that makes it mono?

[skathed]

the wasnt any left to right fade when i did it. sounded a bit flat but rear is only a fill its the front that really matters. guess its user preference and how picky you are with sound quality. i did it when i was broke, now i have a 4ch amp best way to go.

If you have two 4 ohm subs wired in parallel then that's a 2 ohm load, run that bridged across 2 channels and you're effectively applying a 1 ohm load to each channel (and not many amps like that).

If you wired the speakers in series it would be no different to connecting them to each channel individually in terms of power output from the amp.

Don't go low Ohm route, amps are more efficient if they are driving higher impedance. If it says 2Ohm capable, it does not mean it will do it very well.
If you have 2x4 Ohm, and 2 channel amp, just wire them separately to each channel. The amp will run cooler and last longer, also you are not screwing with dynamics of a speaker when they are not in parallel/series*.

* if you have 2 same speakers here is an interesting experiment you can do: wire them parallel to each other (but don't hook them to the amp) and gently but quickly push one of the speakers in, and see how much other speaker comes out. You will be surprised by the effect.

Depends what kind of efficiency you're talking about...
Financial and spatial efficiency is better running an amp at low impedance (i.e. a smaller, cheaper amp is needed to deliver 100WRMS at 2 ohms than to deliver the same at 4 ohms)

Yikes haddnt come back to this thread in awhile.. its just running the 6x9's as no room for a sub, been installed for awhile now and happy with it

[Emperor]

Its a sony amp and 6x9s... it'd be a blessing if they both blew

Nah, but serious, they'll be sweet. Aslong as the gains aren't cranked and trying to pump out sound comp material haha

[eskimo]

haha, not cranking them hard, was just after a better sounding system than the factory set up.
