What is going on - help please!

AGES ago i bought the following;

Sony: XM-502Z - 2 channel Amplifier - 250w
2 x 100 Watts Max @ 4 OHM.
2 x 50 Watts RMS @ 4 OHM.
2 x 125 Watts Max @ 2 OHM.
2 x 60 Watts RMS @ 2 OHM.
1 x 250 Watts Max @ 4 OHM Bridged.
1 x 120 Watts RMS @ 4 OHM Bridged.

SONY-XS-L121P5 - 12" 1200w peak
12" Pentagon series
Rubber surround
Frequency response 18-2000Hz
Power range 80-350watts RMS
Peak power handling 1200 watts
Sensitivity 89dB

So i bought a Renegade amp wiring kit, got a mate to help - and fitted it. Worked for about 30mins then we realised the ground wasn't connected too well and before taking the live off/disconnecting we moved it and POP!

So i got it repaired - was apparently the transformer that went - so i got that repaired. But now it won't work with my subwoofer - rang the sony repair centre up - they say it can't handle subs and is only meant for speakers!? The sub works for a split second then cuts out - but my 6x9's work really well on the amp! But i wanna Sub! :(

Is this correct? I know Sony aren't the greatest but i just want something with a punch. I have been wiring it up bridged btw,

HELP please guys!

Thanks,

Jim

if the repair place ses its not for subs theres a good chance it aint and are you sure you can run it bridged?

[Cassie-Nova]

Well i originally had it running bridged - it has a switch on it.


Selectable Low Pass Filter OFF/80Hz.

One for a bridged subwoofer, and one for a set of speakers.

Should a 250w Amp be able to run a 1200w (350w) sub?

Thanks guys

If its a 250W amp then you've got a 1200W sub :wink: but yes; that amp should be able to run the sub but its not the best amp to use for the job though -

1 x 120 Watts RMS @ 4 OHM Bridged.

...Consider your Sony Sub runs at 350W RMS @ 4ohm, the amp is way underpowered.

Have you got the sub wired into the outputs right? Checked the amp isn't overheating?

[Cassie-Nova]

The amp doesn't even get the chance to overheat mate, just get a seconds worth of Bass when it does power the sub then it cuts out.

So i need a new amp then :( ?

[Jack]

Did you say it was working Ok when running 6x9s, its just the sub it doesn't like? Weird...

p.s.... did you get me pm about the glass postage prices?

[Cassie-Nova]

Ok, so i think we have established that YES< My amp won't power the sub

Any thoughts on a good amp that i could use to power the sony 12" sub please?

Thanks

Jim
