Skar Audio RP-800.1D Monoblock Class D MOSFET 800W
Taramps Smart 3 Bass 0.5 to 2 Ohms 3000 Watts RMS
Big bass systems need headroom, and this Taramps model leans into that with a 1 ohm mono layout and class D amplification. That combo suits a trunk setup where you want strong output without turning the amp section into a space hog.
The LED monitor indicator gives you a quick visual read, which helps in a dash-to-trunk installation where you’d rather catch a fault at a glance than chase it later. Compared with the smaller Skar Audio RP-350.1D, this one belongs in a much more serious build, and the honest trade-off is that it asks for a more capable electrical setup.
Strong Points
- Mono design keeps bass duties focused instead of splitting attention across too many channels.
- Class D layout usually means less heat for the amount of output it’s meant to handle.
- The LED monitor is useful in a real trunk install, where quick status checks matter.
- Full-range support makes it more flexible than a sub-only amp in mixed audio setups.
Things To Consider
- That 1 ohm emphasis suits a proper sub build more than a casual factory-speaker upgrade.
- Higher-output gear like this tends to make wire planning and ventilation more important.
- Owners often end up taking extra care with gain and crossover setup so the system stays clean.
Feature Snapshot
Who It Suits Best
You’re the right fit for this amp when your car audio build already centers on a dedicated subwoofer and you want serious output.
Where A Sibling Pick Shines
Taramps Bass 400 2 Ohms Monoblock Amplifier 400 Watts Rms suits a simpler starter setup that doesn’t need this much electrical demand.
Four-channel amps are often the practical middle ground, and this Yaeccc model fits that role with room for multiple speaker runs. It makes sense in a daily driver where you want bass support plus broader cabin coverage, not just one loud corner of the system.
The full-range design helps it work beyond a sub-only task, though you’ll still want to match it carefully to your speaker plan. Compared with the mono-only Taramps picks, this one is for people who want routing flexibility more than a single-minded bass section, and that flexibility usually comes with a more involved install.
What We Like
- Four channels give you more routing options than a single-channel bass amp.
- Full-range support opens the door to broader system layouts.
- The 12V design suits standard vehicle electrical systems.
- Useful for a build that needs both sub and speaker coverage.
Room For Improvement
- Multichannel setups usually take more planning than a simple monoblock install.
- Its broad flexibility can also make tuning less straightforward for first-time installers.
- Clean cable management matters more here because more outputs can mean more clutter.
Technical Sheet
Right Fit For
You’ll get the most from this one in a mixed audio setup where speakers and bass both need attention.
Look Elsewhere When
Skar Audio RP-800.1D Monoblock Class D MOSFET Amplifier with Remote Subwoofer Level Control, 800W suits you better when the whole plan is a focused subwoofer upgrade.
This AUDIOZERONE monoblock sits in a useful middle zone for bass-focused installs. The 1 to 4 ohm stability gives you more breathing room with sub wiring than a stricter amp, which matters in real garages where parts get swapped over time.
It also includes a low-pass crossover, so the amp can keep higher frequencies out of the sub path, and that usually helps bass stay cleaner. Compared with the Taramps HD 3000, it looks more approachable for a moderate build, though the trade-off is that it won’t suit the same level of output ambition.
Highlights
- 1 to 4 ohm stability gives you more wiring flexibility.
- The low-pass crossover helps narrow the signal toward bass duties.
- MOSFET power supply design is a useful marker for a serious car amp layout.
- Mono format keeps the install focused and easier to plan.
Small Caveats
- The power ceiling sits below the heavier Taramps option, so huge systems may outgrow it.
- As with most sub amps, tuning still depends on the rest of your setup.
- Heat management and cable quality matter more as output demands rise.

The Right Fit
You’ll appreciate this most in an entry-level bass system where easy setup matters more than chasing the loudest possible output.
Swap It Out When
Taramps Smart 3 Bass 0.5 to 2 Ohms 3000 Watts RMS suits you better once your build moves into larger subwoofers and higher demand.
Stepping up from the 350W Skar Audio unit, this 800W version gives you more breathing room for a larger sub or a system that’s grown over time. The remote level control still matters here, because the extra output can be as much about control as it is about volume.
That makes it a sensible middle upgrade for someone who has already outgrown a small starter amp but doesn’t want to jump to the biggest Taramps option. In a sedan trunk or small SUV, that balance tends to feel practical rather than flashy.
Reasons To Buy
- More output headroom than the RP-350.1D.
- Remote level control helps you shape bass for different drives.
- Monoblock class D layout is still easy to plan around.
- Works well as a growth step between entry and high-output systems.
Softer Spots
- It still focuses on one sub path, so it won’t replace a multichannel amp.
- Big bass gains still depend on the rest of the system being matched properly.
- Some installs may need a little more space than the smaller RP-350.1D.
Quick Facts
Built With In Mind
You’re a fit for this amp when your current system needs more punch but still values a simple monoblock layout.

Taramps Bass 400 2 Ohms Monoblock Amplifier 400 Watts Rms is the easier path for a smaller install that doesn’t need all this adjustment.
How To Choose The Right Car Amps For Bass
Start With The Subwoofer Load
Impedance, which is the electrical load measured in ohms, tells you how hard the amp has to work. A 1 ohm or multi-impedance amp gives you more wiring paths, while a 2 ohm design often suits simpler builds.
That choice matters because a mismatch can leave you underusing the amp or narrowing your upgrade path. For most bass setups, the right load is the one that matches your subwoofer wiring without turning the install into a puzzle.
Match Output To The Rest Of The System
RMS power, the continuous output rating, tells you more than a peak number ever will. A 3000 watt-class monoblock belongs in a serious bass build, while 350W to 800W is often enough for smaller trunk systems or daily drivers.
The honest read is that more power only helps when the enclosure, wiring, and electrical system can keep up. A bigger number can feel exciting on paper, but a clean, stable setup usually sounds better in real use.
Choose Controls That Fit Your Routine
Features like low-pass crossover, bass boost, and remote sub level control affect how easy the amp is to live with. A crossover trims higher frequencies so the sub stays focused, and a remote knob lets you soften or raise bass from the front seat.
Those controls matter most in cars with changing listening habits, like a commute in the morning and bass-heavy playlists at night. If you want less fiddling, a simpler amp can be the smarter call.
Think About Install Space And Heat
Class D amps are common here because they stay efficient and usually take up less room than older styles. That helps in tight trunks, under-seat spots, or compact enclosures where airflow is limited.
Still, higher-output amps need room to breathe and clean cable routing to stay reliable over time. A well-placed smaller amp can be more satisfying than a crowded big one that’s hard to cool or service.
What To Weigh Before You Click Amazon
Hidden Buying Traps
A common mistake is chasing output without checking impedance and wiring compatibility first. Another is ignoring the difference between a mono bass amp and a multichannel amp, which can leave you with the wrong tool for the job.
Mounting space also gets overlooked. A compact amp can save you from a cramped trunk install that’s hard to service later.
The Case For Spending Up
Higher-tier amps usually buy you more tuning control, stronger output headroom, and better fit for complex sub setups. That extra headroom matters when your system grows, because the amp doesn’t feel strained as quickly.
The upgrade is worth it when you already know your sub plan and want more control over how it behaves. For simple factory replacements, the added features can be more than you need.
Frequently Asked Questions
What makes a good amp for bass in a car?
A good bass amp gives you the right impedance support, steady RMS power, and crossover control for your subwoofer. It should match the rest of your system instead of overpowering it.
Is a monoblock amp always better for subwoofers?
Monoblock amps are usually the cleanest fit for a dedicated sub setup because they focus on one channel. A multichannel amp can still make sense when you need bass and speakers handled together.
How much power does a bass amp really need?
That depends on the subwoofer, enclosure, and how loud you want the system to feel in the cabin. Small daily-driver setups often do fine with modest output, while larger builds ask for more headroom.
Why do some amps list several ohm ranges?
Multi-impedance support gives you flexibility in how you wire the subwoofer. It helps the amp work with different load setups without forcing a single wiring path.
Do remote level controls matter?
They do for people who want quick bass adjustment from the front seat. That kind of control is especially handy when one playlist wants more low end than another.
