D’Amore Engineering - 5 Channel Car Audio Amplifier, 660 Watt Amp Car Audio with 2 Ohms Stable, Clean D Amplifier Technology & MOSFET Power Supply (E660.5)

Attractive unit, doesn't take up too much space, connections are secure, adjustments are simple. Sounds great - plenty of power, good detail and separation - and as class D it doesn't heat up or draw too much current. My only very small gripe has to do with the fact that I had to install the unit transversely at the back of my trunk, which makes seeing those adjustments on the left side difficult. As this cost me about $250, I would also say this is a very good value.

I have needed a new 4 channel amp for my upgraded mids and highs. I currently was running a 400w 4 Chan. To my doors and saw this 700w from D’Amore and knew I had to have it. Tony (the engineer) who is the owner and designer of this amp has had an extensive career in electrical engineering and amp design. Although this is on his lower end of price range it sounds amazing. Compact in size and has the power behind it. Very happy with my purchase.

It's sounded better than I thought it would. Definitely not sound pressure ,more like sound quality in my opinion.

Great amp! 700.4 has great sound quality! Can’t beat it for the price ! And it’s Made by Tony! Definitely I’d buy it again

This amp is by far the cleanest sounding amp I’ve used to date besides JL Audio’s VXi line. I’ve used many amps, and have tried about 5 different amps for my vocals, and couldn’t get as clean, crisp, and sharp of a sound I love that I get from a well tuned studio quality home theater with time alignment and staging. As for a stand alone amp for bass, mid bass, high bass, midrange, and tweets, this is the best amp I’ve ever used in my car to date. Buy one people, and I bet you’ll say the same thing. Thank you D’Amore for “clean D” class D!!!!!

I can't get the 5th channel to do anything. I've sent D'amore 2 emails and given at least a week for response time on each of them and haven't heard back diddly. I had it for the 3 months before installing, so I missed my return window. I'm pretty sure it was an Amazon return because it was missing the manual and mounting hardware and spare fuses. I'm pretty pissed at D'Amores customer service for not even answering questions about it. That's pretty crappy customer service from a company that's supposed to be upper end. I guess I'll stick with CT Sounds. VERY dissappointed with D'Amore.UPDATE 5/5/23: About a week after my initial review, D'amore finally sent me an email saying they would need to look at the amp. I sent it back to them and after a couple weeks, they sent an email with a tracking number saying they are sending a new amp. I received the new one a few days later and installed it. All is okay with new one. Good amp for a decent system in a car. Seems to be very efficient and has good sound quality. I'm changing from 2 to 4 stars. Only 4 because I think you can get a comparable amp for a lot less money.

I like everything about this amplifier. It's chassis size allowed for under seat installation. The connections are made easily with set screw connectors easily accepting suitable wiring. Settings and adjustments are easy and not iver complicater with a quality feel. This amplifier is a mini powerhouse. It pack serious punch to drive my midbass drivers. The amp in my book delivers on all aspects. I will be adding more of them to my system. I highly recomend for installs that need a lot of power in a small footprint. Very pleased, well done D'Amore!

Currently have (2) RF Punch 100ix amps from the 90s. Nothing wrong with my current setup, but figured I'd give this 4 channel a try so I can use my Pioneer in active mode to take full advantage of the head unit's abilities. Pulled the amp running my Infinity 6.5" components and put this e400.4 in. Once all connected and buttoned up, I turned everything on and received a high pitched squeal, then silence. After further troubleshooting I found that channel 3 was the only functional channel. Channels 1 and 2 have zero output, while channel 4 only outputs a loud hiss when the RCA is connected. I had high expectations but those were dashed, causing serious doubts with the e750.1 I ordered from the manufacturer website that will arrive in a couple days. Debating whether to just return this for my $ back or replace with another. I now question the quality control and longevity if I do receive a functional amp. Keep in mind, I'm coming from some 30 year old amps that were the bees knees in my car audio installer days. Looks like they might still be better than the brand new offerings of today. Boo!
