    • Superb Amp
This 5-channel amp is superb. The quality is high. And it sounds amazing. If you want a dedicated channel for your sub, which is a smart idea if you have a strong power-hogging sub, and you don't have the space or just frankly don't want to deal with a mono amp just for your sub, then this Planet Audio AC1800.5 would be perfect for you. My last sub fried my older amp when I connected it. It almost burned down my entire car, but I caught the fire before it spread. So, I realized then that it would be best to buy a well-made, powerful amp with a dedicated channel for the sub. I find the subwoofer level control on this amp pretty useless. It's a separate part that you can keep in your dash that has a cable running to the amp. All it does it control the subwoofer level. Most head units can do this alone, so this is a useless part for me. Otherwise the other controls on the amp are pretty detailed. You can adjust almost every aspect you can think of. The wattage is also plenty for most sound systems. It was a little difficult to install, but frankly most amps are in many instances. I installed this into my 1990 BMW 325i. The best place to put an amp in my case is to attach it to the back wall in my trunk. But man... it was an absolute pain in the arse! Myself and two others struggled to line up holes and drill through the metal frame behind my backseats. It was a huge relief when we got it installed. It would be nice if Planet Audio had a template to make vertical installation easier. Just FYI: make sure everything is connected and the amp sounds how you want it to sound before installing it, especially if installing at an awkward place in your car. It's cool how the logo lights up, too. I do think the manual could be written better, though: It fails to mention what kind of fuse you need for the power cable. You can consider this amp as pricey. But you get A LOT with the amp: a ton of controls and dedicated channels. Plus it looks cool and performs superbly. It's great for any genre of music: rap, rock, metal, jazz, pop, etc. The longest I ran this amp at any one time was about 4 hours and it never shut off. A good amp is VITAL for a dependable, great sounding car audio system. Planet Audio can help you get there. Overall: 4.5 stars which rounds up to 5. This puppy will last for many years. Thanks, Planet Audio and Amazon! ... show more

    • WOW just WOW for only $123 smooth, and loud
This review is for the AC 1800.5. I was hesitant that is accepted balanced differential inputs, but it does. Works perfectly with my BMW Hifi OEM head unit. It is installed with OEM midrange speakers and tweeters. This amp overpowers them. So i recommend replacing OEM mids and tweeters speakers (if you want it louder). I had to cut out my BMW's Ski hole. The 5th channel is connected to A Planet Audio AC10D 10 Inch Sub, mounted in a BBox E10SV Single 10" Vented Carpeted Subwoofer Enclosure. I highly recommend this combo. Links are here: Sub: https://www.amazon.com/gp/product/B007T2PE7G/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 Box: https://www.amazon.com/gp/product/B0013MWT9O/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 I'm not sure if it’s my experience picking out components box is tuned to 39 hz, and speaker requires a 39 Hz box. The speaker’s input wattage max is higher than amps, because if you overload a speaker it’ll blow, but if you overload an amp, it will just shut down. So I always pick a stronger speakers. When tuning the subwoofer channel crossover and bass boost i was able to get a flat bass response (hit hard, and boom) with the bass boost almost to minimum, and increased the gain accordingly. I think the flat response was easy to obtain, because the speaker was so well matched to the box. (granted speaker placement was also key). The final position of sub was it long way up (vertical). When I moved long way horizontal, bass output decreased dramatically. The OEM speaker output cannot keep up with the bass output. But as is for me, it’s loud enough. I am keeping OEM highs, until I accidently blow them up. What’s not advertised is channel 1 & 2 and 3 & 4 can be bridged tri-mode. I am planning on using Tri-mode to power the OEM under seat 8” subwoofers. So This amp has 7 channel potential. I need install passive cross-overs. The capacitor and inductor specs are provided in the instruction manual. Over all for $200 I have a loud system with super low low bass, and good/better hard hitting tight bass. Because I do not have experience with this brand, I wasn’t sure how reliable it is. So I bought the additional Square policy which will replace/repair it for 4 years. I'll update this review if or when this amp stops working. If I don't revise this review, then it never broke, and I sold the amp with the car. ... show more
