Every installation amps that matches
39 models match this page. The 15 above are covered in detail; the rest are listed here with their published specifications.
Installation Amps by the numbers
Measured across all 39 models in this category, so «wide», «short» or «expensive» mean something you can check.
How to Choose the Best Installation Amps
Power Output (RMS)
Don't get fooled by peak numbers. Look for RMS power ratings that are realistic for your needs - 200-400 watts per channel is a good starting point for most small to medium installations. More importantly, consider how that power translates to headroom; you want to avoid constant clipping.
Damping Factor
A higher damping factor (ideally over 300) means tighter, more controlled bass response, especially important when driving passive speakers. A low damping factor can result in a boomy, undefined low-end thump that muddies the mix.
Connectivity & Routing
Check for balanced XLR inputs and outputs - essential for minimizing noise. Multiple speaker zones and bridgeable operation offer flexibility for different setups. A few decent EQ adjustments are a bonus.
Cooling & Reliability
Installation amps live a life of their own, often running for hours. Look for efficient cooling systems (heat sinks, fans) and a reputation for reliability. Cheap components often mean early failure.
Signal-to-Noise Ratio (SNR)
A higher SNR means less hiss and noise in your signal. It's not a huge deal for most applications, but it's a sign of overall build quality and can be crucial in quieter environments or when recording.
Buying Guide
At this price point, you're making trade-offs. Don't expect premium features like advanced DSP or ultra-low noise floors. Most amps will have a slightly harsher top-end response than more expensive units - listen for that ice-picky high-frequency edge. Prioritize reliable power and clean headroom over fancy routing options; a stable amp that delivers consistent performance is worth more than a bunch of features you won't use. Consider used options - you can often snag a higher-end model for a good price.
How This List Is Built
We don't play these instruments — we're a catalog, not a review desk, and we'd rather say so than pretend otherwise. This page covers 39 installation amps from the Thomann catalogue, which is the largest single source of specification data in this category: 15 in detail, the rest listed with their specifications.
Position is computed, not curated. We parse the manufacturer's own description into actual values — nut width, scale, fret count, fingerboard radius, size, alloy — and rank on them: how many specifications a model has published, how many of them are measurable numbers, and how precisely it meets this page's criterion. A product image adds a little. Price is not a ranking signal: it tells you nothing about whether a neck fits your hand. The same inputs always produce the same order, so nothing here is shuffled to look fresh.
What this list is good for: narrowing a category down to a shortlist by spec and budget. What it isn't: a substitute for hearing an instrument. Before you buy, read hands-on reviews and, where you can, play it. Full methodology.
