Sony Amplifier

This is an amazing amplifier. Awesome sound quality and extremely powerful. As I checked, on nearly full gain, as I was using my old experia phone( never set nearly full again with a car output or laptop output), with bass boost adjusted just before clipping, I got a current of 37amps, @14.6volts and rms of over 300watts @4ohms load. I tested it on 2 ohms and current peaked to shocking 58amps@14.4volts, couldn't measure the rms but was definitely around 600watts as It made voice coils of 2 12" subwoofers crazy hot to the point it started stinking,as I increased bass boost to full,never do that. Conclusions: awesome amplifier of you are carefully and knowledgeable about audio equipment. Edit: again tested with a better precision Got easy 360watts@4ohm and working great after about an year of use. Will proivide more info at 2ohms and even 1ohm when i will get more subwoofers which are on the way..... Edit2: more precision getting 360watt rms @4ohms at 1%thd with just 32amps about 90%efficiency Also if gains are set at full blast, 50 volts can be achieved at output.. And yes the voice coils on two jbl1500hi got overheated to an extent where about to smoke.

Great little sub amp.

This is one of the finest mono Amplifiers in the 325 RMS range. I am currently running JBL 1300 Watts Bass tube with this. I see a significant difference in the bass quality versus running the same woofer on a bridged 4 channel Sony 1004 amplifier. The GS100 brought a real deep bass. Loved the controls as well. BTW this amp can also be really loud for all those wanting a thumping Bass in their cars.

I have this hooked into a dual 2 ohm Quantum 10" 2000w Competition series woofer with a 180 oz magnet. Also using a Rockford Fosgate capacitor, which seems to be made to work perfectly with this unit. All I can say is wow! I took a gamble purchasing this back when they were selling for 549.99 and bought directly from Sony. Put it to the test, and I just purchased this one at 153.99 prime. Going to use the second one to power the 2 Rockford Fosgate 8" door subs that were ordered with this amp in my Mustang. This amp if used with a capacitor, will push at the very least 1 2000 watt dual 2 ohm competition 10". I have a good friend in the audio buis that also cannot believe the performance I got after install. Crutchfield also gave this amp a 5 out of a possible 5 score, and has a good review. If your new to the game, crutchfield is a good source of information.Hope this helps with your decision, you won't be dissapointed.
