Review: Solid performance, awesome budget amplifier! - DB 45 is an awesome budget amp! Replaced a couple Boss amps that I didn’t do my research on first (amplifier benchmarking) and I spent less money on this and then I did for the other two. Rocksolid amplifier. It does warm up pretty quick when you’re pushing it but it did not get hot. Very happy with the purchase. Only problem I have is that when using the low pass option for a sub there is no sub sonic filter. At least not adjustable, I was playing 19 hz tone to my sub and it was flopping pretty good with no audible sound. Was hoping it would have sub sonic filter set for either 15 Hz or 25 as an option. Update 8/9/2019: I've had this amplifier now for around 10 months now and it's still going strong. Have it hooked up through a pair of 50amp AC to DC power supplies in my garage powering 2x 400w RMS Floor Speakers and a 425w RMS Polk Audio 15" Sub. It definitely pushes out the rated power (as dyno benchmarks have also confirmed they hit around the rated CEA RMS power as stated). Extremely loud and clear music (my neighbors can affirm this too... ). I have a couple other car amplifier / custom sub installs in my house where I still have poorly rated amps and I'm looking forward to purchasing more Rockville products to replace those amplifiers very soon. They will not disappoint!

Speaker and wiring terminals are higher quality than other models in its price bracket and offer tight, clean, reliable connections. adjustable low pass hi pass crossover. RCA output jacks make system expansion even easier, too! I’m not just impressed by the great value of the amp but the features you get, too. I’m impressed that such an inexpensive, solid amp still offers features others don’t.

### ⭐⭐⭐⭐ works great as rated
*by S***Y on September 27, 2025*

Worth the price. Used amplifiers in the 90's and been out of the car audio world for quite a while. I ended up buying a sound stream amp because they were all the rage in the 90's only to find they are not so good now. It was blown anyways on a channel from the start. So went looking for an alternative that was as advertised. This comes with a dyno sheet from the actual test for the individual amp. I just have it hooked up as a 4 channel amp so can't say much on running it for a sub. It works great for what I use it for but is quite large. It doesn't really fit under the front seat but that's where it is.
