Note: Please be specific about which amplifier model you're interested in
Prices are as listed and firm
Mono Amplifiers(1ch amps used for powering subwoofers):
Formula Mach-4000(photos 2-3)
$50
2 channel amplifier, but the 2 channels channels can be used together in what's called bridge mode which gives power to run a subwoofer
spade terminals
made to look like a Kenwood from the late 2000's
unable to any information or official power ratings, but based on the fusing and similar amps I would say it's:
2 x 100-110watts rms @ 4ohms
2 x 135-150watts rms @ 2ohms
1 x 270-300watts rms @ 4ohms in bridge mode
Power Acoustik RZR1-2500D (photo 4)
had 5 of this model for sale, all 5 have been sold but still have one that I'm using in one of my vehicles that I'm willing to also let go for $80(which is what the others sold for)
650w @ 2ohm
450w @ 4ohm
Made in Korea
Class D
Adjustments: gain, bass boost, low pass frequency, subsonic
8 gauge power input
Has all its endcaps
Exact same amp as: Soundstream Picasso Nano PN1.650D, Precision Power Ion I650.1, Dual DA801D
Other: Connections for high level inputs and bass remote(high level input adapter and bass remote/cable not included). Endcaps can be taken off to make it even more compact.
Even though these are rated for running only to 2ohms, many people have used them just fine at 1ohm which makes this put out around 900w. Of course this is at your own discretion if you decide to try this since it's not exactly recommended by the manufacturer.
Brand: Earthquake
Series: PowerHouse
Model: PH2000W/D (photos 5-6)
$100
Class: D (Earthquake calls it Class J but it's the same as Class D)
Output (Rms):
1000w @ 1ohm
700w @ 2ohm
450w @ 4ohm
Uses spade type connections for power inputs and speaker output(I include some spade connectors)
Adjustments: gain, lpf, bass boost
This amp would be the limit on what you can run on stock electrical. For more than 1,000w you need to do what is known as a Big 3 upgrade to the charging system, otherwise you start starving the amp and your vehicle's electrical system.
Alpine S-A60M(photos 7-8)
$120(sells $220 new and $150 used)
600w @ 2ohms
330w @ 4ohms
easily outdoes its ratings. in real world with music it does about 450w @ 4ohms, and over 800w @ 2 ohms
Adjustments: gains, bass boost, low pass frequency
4 gauge power input
Other: Rca output, bass remote connection(bass remote/cable not included),high level(speaker wire) input option through rca's with special adapter(I have some and can include if you plan on using high level input)
This amp and it's previous versions have regularly been voted as best monoblock of the year for about 20 years straight. I would have to agree with them because these are my favorites of all the amps I have owned, I've owned about 5 or 6 of them and 4-5 of the MRV-M500 which was its previous model. They are compact, powerful, reliable and clean sounding.
Earthquake Mini D2500 (photos 9-11)
$165(sells new for $425)
2,000w @ 1ohm
1,800w @ 2ohm(likely more in the 1,350-1,500w range. its other ratings should be accurate though)
850W @ 4ohm
4 gauge inputs(true 4 gauge not oversized, so adapters to 1/0 gauge won't fit without minor trimming to the adapters)
10 gauge speaker outputs
Includes brand new replacement bass knob and cable
Adjustments: gain, lpf, subsonic, bass boost, bass boost frequency

In order to run this properly, use pure copper 4gauge wire for up to 1,500w, and 0gauge wire for above. Big 3 upgrade should also be done to your charging system.
The following 4 amps are all high power, and require pure copper 0 gauge wire, Big 3 upgrade, and likely a high output alternator as well, in order to fully push these amps.
Soundstream TXP1.6000D (photos 12-13)
$165
700w @ 4ohm
1,200w @ 2ohm
2,300w @ 1ohm
(outperforms its ratings)
4 gauge power and ground inputs
8 gauge speaker outputs
adjustments: bass boost, bass boost frequency, gain, low pass, high pass
clip light on the amp
cooling fan
Soundstream's TXP line are probably some of the coolest looking amps out there, being made of aluminum, having plexiglas windows to show off the guts, and a l.e.d's that light up a spider.
but they don't just look cool, they're all around great. being powerful and very compact.
this model does pretty good even when only being fed with 8awg wire. most powerful amps are current hungry and always require thick wire, but with this one you can use smaller wire depending on how much power you plan to put out of it.

Nakamichi NRO-3000 (photos 14-18)
New in package
$185
1,000w @ 4ohm
1,600w @ 2ohmm
3,000w @ 1ohm (this is the only one they didn't rate properly. meets its 4ohm and 2ohm ratings, but people typically measured 2,400-2,600w at 1ohm, which is actually what you would expect mathematically based on its 2ohm rating)
1 gauge power and ground inputs
4 gauge speaker outputs
bass knob
cooling fan
high level inputs
Adjustments: gain, lpf, hpf(can also serve as subsonic), bass boost
Soundstream TXP1.12000D (SOLD)
1,300w @ 4ohm
2,300w @ 2ohm
*4,300w @ 1ohm, pretty sure it was meant to be 3,300w
people that have dynoed it got 1100w, 2100w and 3100w certified, so should have no problem doing the rated 1300w,2300w,3300w dynamically.
Taramps Bass 3k (SOLD)
3,000w @ 1ohm
1,920w @ 2ohm
1,000w @ 4ohm
NVX XAD-14 (photos 19-22)
$235
new in package
1,100w @ 4ohm
2,000w @ 2ohm
3,000w @ 1ohm
0 gauge power and ground inputs
bass knob with power light
tiffany style rca inputs
clip indicator light on the amp
Adjustments: subsonic, lpf, gain, bass boost
5 Channel Amplifiers: For powering an entire sound system(4 door speakers plus a subwoofer)
NVX JAD900.5 (SOLD)
$165
4ohms: 70w x 4 + 220w x 1
2ohms: 115w x 4 + 440w x 1
Bridged mode: 230w x 2 @ 4ohms
Class D
8 gauge power inputs and speaker outputs(I will include a pair of 4 gauge to 8 gauge adapters so you can use 4 gauge wiring for the power inputs)
Comes with brand new replacement bass knob and cable
Adjustment: gain, lpf, hpf, subsonic, crossover switch, channel mode switch
Can be used in 5/4/3/ or 2 channel operations
Works even if you only have 4 rca preamp outputs. Has a feature where it can extrapolate bass internally from the other channels and use it as the signal for the subwoofer channel.
Very compact for something that can drive an entire system, should fit under the seats of most trucks or suv's. And it has a decent amount of power to it.
