Amazing little Amp!

I ordered this with the Alpine ILX-W670 and what a difference it made! I tried the W670 by itself first without the amp and then connected the amp and it made a BIG difference in sound quality and detail. I installed it in a 2018 Nissan Titan with Infinity speakers. I already had the Maestro RR module, so I just had to add one connector to it (supplied with the Maestro) and re-flash it to retain the steering wheel controls. Watch some videos on how to install the amp and how to configure the Crossover/4-Channel/RCA settings and it's pretty straightforward. I had to cut the speaker wire connection on the Maestro harness (Idatalink Maestro Acc-HU-ALP1) for the W670 and connect the speaker wires from the amp to the wires going to the speakers. Well worth the money. Gives SERIOUS punch and clarity to my system.

Great Entry Level

I paired this amplifier with an ILXW650 Headunit in my 04 IS300 bypassing the factory amplifier and powering JBL speakers and tweeters and OMG this setup beats most entry level premium audio packages in even newer cars. The small footprint and close proximity to the headunit significantly simplifies the install and really enriches the audio experience. Sure, you’re not hitting ridiculous db levels or winning any competitions, but for a daily driver, this punches above its weight class. Highly recommend.

Amazing sound, great bang for your buck!

I used to do mobile audio and alarm installation so i have extensive knowledge on the subject. Alpine makes EXCELLENT products, always have, and still do. This amp was added in my 2014 honda pilot which i wanted to keep the stock head unit. It has alpine type R separates in all 4 doors and this little amp now powers them and it sounds AMAZING. I had the speakers connected to the stock deck since i bought the car new in 2014 and i was really missing out. Highly recommended- its paired it with the audio control LC7i PRO. Sounds absolutely astonishing for the amount spent on everything. If you're looking to keep the install simple and nothing crazy, this is a great option. Also, i have it sitting under the carpet below the glove box.

Not working

The geek squad installed it with the Alpine speakers I purchased with the Alpine head unit from best buy. They had run out of the Alpine 445 and 450 power ampI have to wait till June 22 for the third attempt to have this unit too work.Geek squad twice fixed the problem and it still stops working.

Worth the buy

IMO, this is definitely worth it. The difference is night and day. If you've never ran amped up speakers, you are missing out. Virtually no crackle in my speakers and so much more power. Adds so much more to your set up. Definitely plan placement because it takes up space and I barely had room behind my head unit.

Great for 3rd gen Tacoma non JBL

I have a factory 2022 Tacoma with the 8" screen, non JBL. I had upgraded the factory speakers with Rockford Fosgate all the way around. The factory rear outputs are so low level that the sound with rear only fader was barely hearable. This amp has made everything very well balanced, clear, and loud. It is now a pretty amazing system while keeping the factory HU. If you get for your Tacoma, the black plug is all of the speaker outputs on the factory HU. Be prepared to take time and splice. Remote ran to cig lighter purple wire.
