Sony Car Amplifier XM-N1004 1000W 2, 3 & 4 Channel Amplifier, Rated Power: 4ohm - 70W x 4, 4ohmBTL - 175W x 2, 2ohm - 85W x 4, Low Pass Filter and high Pass Filter, Black

Bought it during festival value for money (@5.8k) did whole sony amp & sub+enclosure setup under 10k becoz of this. The bass and sound quality improved a lot(even with stock speakers). Sub is sony xs nw12002 12 inch 300W rms (2.5k). Only problem is with heating. I have kept it in cabin, under seats even with a.c on amp is heating. Didn't cutoff till now due to heating (only regular short trips half to 1hour). Will update on it after long trips. Amp is now poweing front both speaker and sub. Front speaker out & Sub out is taken from headinit itself low rca outs . Rear speaker powered by sony head unit itself (sony headinit has a built in subout so all 4speaker & sub working) (2frnt from amp+2rear from headunit). Bass is punchy but not boomy. Clarity from stock speakers of toyota has improved a lot (planning to upgrade next). You can include 4 speaker and 1 sub of total RMS of 4 speaker is around 140watts (as 70W x 4 is rated out at 4ohm so 4 speaker at 140w won't be an issue dnt forget to match impedence also) and sub is at 200 watts (175W x1 rated out for bridged set up at 4ohm). Package didn't have any screws for attaching amp to floor of car. Warranty cards were there in the box. Value for money at the end of the day that's it....

Pretty clean sound for a budget amplifier. It’s generates rated power as promised but you will have to fiddle with the gain knob as my HU (Pioneer - DMH AP6650BT) preamp voltage (4V) isn’t exactly as advertised. Also, it does heat up on prolonged usage, especially the 500w 2-channel on BTL as I’ve hooked it up to a 10 year old pioneer champion subwoofer (400w rms). Been using it for 2 months now at 2V gain setting at almost 50-75% HU volume and hasn’t given up on me yet. Note: It does tend to reduce volume gradually as it heats up while in use so I have to increase volume accordingly. Never pushed it to distortion so not sure of it. Speakers: Focal access 165 (2-way front & coaxial rear) Subwoofer: Pioneer champion 400w rms SVC Power cable: 4 AWG OFC (100A fuse) & 2x8 AWG Splitter at 14.04V from source Speaker wire: 14/33 CCA Also, once I’ve connected the speakers to the amp the Mid woofers really started to shine, earlier I used to run my tweeters at a -3db setting to cut out the harshness but once I’ve installed the Xplod series I’ve notices a relatively smooth response from my tweeters at 0db and kept it there. Only time will tell about it’s reliablity as I’m pushing these as hard on my daily run.

1. The output transistors are A1908 , C5100 these are high speed Japanese transistors designed for audio use mostly found in the classic Japanese amps . 2. The Input is single stage (Not double differential input stage) It is not a a fully complimentary amplifier but the design will meet all car audio applications . 3. The component selection of Mosfets , High Speed Diodes & Inductor of the voltage step-up circuit is good and robust with a clean output . There is not much buffer capacitance on the power lines , how-ever Sony has kept space for a larger capacitor on the PCB should someone would like to upgrade it . 4. PCB design and quality is good and handling of high current lines have been done well . 5. The chassis is well designed and robust , facilitates opening of the Amp easily to service common parts and has a built in fan cleverly placed . 6. The cross over circuit is good and works well and is of a practical design , it uses smd components , smd is yet not very well accepted in high end audio due various audio requirements . However ' The DC offset measured was 16mv on 3 channels and 32mv on one channel . The Amp is easy to set up and flexible with regard to input / output . Sound Quality --- I have a 4 way Active cross-over setup and this Amp for Mid range and human ear is most susceptible to distortion in the Mid range. The Amp plays clean with a warm sound in the lower mids and an accurate response all over . (Bench-marked using own made 8inch Mid Drivers X 8 units & Tannoy Dual Co-concentric x 12 units ) This is a very good Amp at it's price range and recommend it .

This product its not good after 3-4 months. its not working properly. some outer Port and switch out of order . This product is weast of money.

I have installed it in diggi of Maruti Suzuki Ignis 2023 Zeta model. As the car is new and I don't want to cut or disturb any part of infotainment system. So I installed wooden parcel tray and installed pioneer oval shape speaker in a tray. I installed the amplifier to a rear side plywood of 10inch slim subwoofer by drilling screws in it. I took out speaker wires from rear door speakers of car and given as high level input to the amplifier. The sound output is so good that it seems an expensive car music system. Bass is too good. Hats off to the pioneer ts-a942fh oval shape sound clarity. Each music beat is clearly audible. Fitting amplifier directly on subwoofer back side results into less use of boot space. Amplifier is really a worth.

Good

Excellent product

Installed this amp to go in my Honda s2000. Short enough to fit in space above the gas tank. I really liked that all of the connections are on one side, and this thing has crystal clear sound even with gain turned up all the way. Install it right (large gauge power cable ran separate from the speaker wires) and you will be happy!

I’m installing this in my 1997 Jeep Wrangler (TJ) because my old one bit the dust. The packaging was of good quality and the size of this amp is considerably smaller than my old one. Only time will tell how this amp does. I mean... it’s going into a Jeep whose owner rides the majority of it with the windows off. Update: Wow! I can’t believe how much better the audio sounds. Now I can actually hear what I’m listening to. Perfect. Mine fits snugly underneath my passenger seat.i just drilled some pilot holes before I screwed the unit into the metal.

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.

Just what i expected
