Great amp like old sony

The following review is for XM-GS400, which is a part of the bundle you are viewing.

Sounds great. No noise. Nice build quality.

tested at 85x4 @ 4 ohms and 240 x2 bridged by PAS.

Nicely under rated. Reliable and clear A/B power and nice cosmetics (esp for recent sony amp)

I like the gs line.

Great amplifier.

The following review is for XM-GS400, which is a part of the bundle you are viewing.

Bought this amp just to try it. I'm impressed. So much so that it's now my "go-to amp" for those customers wanting more power then a head unit can offer. It is physically smaller then I expected which is great for tight spaces. With it's forced air (fan) cooling, I shouldn't have to worry about heat. The noise level is MUCH lower then I was expecting. Even with the gains relatively high (about 3/4) it's dead silent from the drivers seat (car parked in the garage). The sound quality is great. It's a very musical amplifier. Great bass, great mids, great highs. Excellent imaging and sound stage. I like this amp over my Eclipse and even over my JL 300/4 which I've now sold. As for the power. It does every bit of what it's rated to do. I thought, for the price, if I needed more power I'd just get a second one and run them bridged. Not the case. This amp has plenty of power. I run the Alpine SPR 6x9s in the rears and a custom 8" component set with hand made crossovers in the front.

User friendly

The following review is for XM-GS400, which is a part of the bundle you are viewing.

The main reason I got this amp was because it has "Auto Turn On" , which I figured would save me time from poking around my 2014 Dodge Avenger. Not only was that TRUE, but I didn't realize until the install that everything else about the amp was going to save me time. The size of the amp made it easy to mount where I was hoping, the TOP mounted knobs made it easy to reach, re-reach and tune. AND BEST OF ALL, the cover makes sure my kid doesn't go in and mess things up! ha. GREAT AMPLIFIER!!! Oh yea, and AWESOME sound quality. It makes my 6x9 sound like I have a subwoofer..which saves me money from actually ahving to buy one!
