Product Brand & Model:

Sony Mobile ES 7547

This amp can do 250x4 @ 2 ohms continuously, not peak.
Also can use any ohm sub on the rear channels as it is switchable for 4 or 2 ohm and 1 or .5 ohm.

You cant beat it for a passive front/sub system. So many features and crossover high enough for active. Plus direct mode that bypasses the crossovers and boost circuitry.

100 amp fuse (25 a channel)

Please read this thread for insight on this amp

http://www.diymobileaudio.com/forum...ssovers/104541-amp-gurus-i-have-question.html

Basicly 250x4 is reasonable listening to music, not sine waves. Great amp

Local buyer couldnt fit it so its back for sale.

Condition of all items:

excellent 9.5/10

Total Price: :

$250 shipped

Shipping Terms: :

Usps with delivery confirmation

Pictures: - Unless you are a Upgraded member, or your last 10 iTrader feedbacks are positive, you must post a picture of the exact item you are selling.







Additional info:

Seems like I sell one of these a month. Only trade interested in is a Sony Es g2100

Can you tell me if chanels 3-4 can be bridged and still do 4ohms on chan 1-2? dumb question I know...
Yes you can. You can do 4 or 2 ohms on channels 1&2 and 4-.5ohms on channels 3&4 depending on choosing high current mode or high voltage. So it will work with any sub on chans 3 and 4.

There is technically two different 2 channel amps in here. I used the front channels on passive comp sets and the rears on a single 2 ohm sub

Also used the amp to power mids and tweets. Kinda a waste to use all that power on tweets though but if youre using a passive setup on 2 channels and a sub on the other two, its the perfect amp.

The beautiful exterior of the Sony Xplod ES XM-7547 only hints at the technological innovations within. Inside, you'll find separate high-current MOSFET switching power supplies (for input and output stages), Non-Negative Feedback design, extra-large MOSFET output devices, high voltage/high current switching (for stability down to 1/2 ohm in stereo), discrete differential inputs, and low boost control. You can expect clarity and dynamic range like you've never heard out of a car amplifier.

If you hunger for the same type of performance in your car that you get out of your home audio system, the XM-7547 amplifier will get you there.
Details:

non-negative feedback design for superior reproduction
high-voltage/high-current modes
single-ended push/pull design for stability at 1 and 0.5 ohm
discrete differential inputs for reduced noise
dual power supplies
MOSFET output power supply
high current MOSFET finals
selectable low-cut (subsonic filter) 7Hz-40 Hz with selectable cut and boost (0-10 dB)
103 dB signal to noise ratio
3-way protection circuits
heavy-duty connectors with brushed aluminum cover panel
continuously variable high-pass and low-pass crossovers (50-4,000 Hz, 12 dB/octave)

No, it's a 4 channel.

Yeah, It does have the option to turn off negative feedback but I liked the sound better with it on. This amp was pretty ahead of its time.

If you want a one amp solution of the best quality (comps up front and sub)and size is NBD, it doesnt get better anywhere imo. Also just great as a sub or just fronts active amp.
