Channel count decides your tuning options for the life of the system, and it is the one spec you cannot change later without buying a different amp.\u003c\/p\u003e\n\n\u003ch3\u003e5 Channel\u003c\/h3\u003e\n\u003cp\u003eFour full-range channels plus a dedicated subwoofer channel. This is the one-amp answer for a factory-replacement build: front stage, rear fill, and bass off a single chassis. It runs a passive front stage, so the crossover between tweeter and midbass is fixed by the speaker maker, not by you. If you want a complete system on one amp and you are not going active, this is it.\u003c\/p\u003e\n\n\u003ch3\u003e6 Channel\u003c\/h3\u003e\n\u003cp\u003eSix full-range channels, which is an active three-way front stage: two channels each to the tweeters, the midrange, and the midbass, with no passive crossover in the signal path. Every driver pair gets its own amplified channel and its own crossover point, set in a \u003ca href=\"\/collections\/digital-sound-processor\"\u003eDSP\u003c\/a\u003e rather than by the speaker.

Four full-range channels drive the front and rear pairs, and a fifth dedicated channel drives the sub. It is the complete one-amp answer for a factory-replacement build running a passive front stage. If you want your whole system on a single amplifier and you are not going active, a 5 channel is the amp.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need a 6 channel amp for an active three-way?\u003c\/h3\u003e\n\u003cp\u003eYes. An active three-way is tweeter, midrange and midbass, left and right, which is six amplified channels with no way around it. A four-channel amp forces one driver pair to share a channel or stay passive, which gives back the reason you went active. Six channels lets a DSP set the crossover point, slope and level of every driver independently. The subwoofer then goes on its own monoblock.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is an 8 channel amp for?\u003c\/h3\u003e\n\u003cp\u003eAn active three-way plus something extra: rear fill on the last two channels, or a bridged pair driving a subwoofer. Every driver gets its own channel, so nothing shares and as little as possible stays passive or bridged. It is the full-active and competition answer, and it consolidates what would otherwise be two or three separate amps onto one chassis.\u003c\/p\u003e\n\n\u003ch3\u003eCan I run a subwoofer from a 5 channel amp?\u003c\/h3\u003e\n\u003cp\u003eYes, that is the point of the fifth channel. It is a dedicated subwoofer channel, separate from the four full-range channels driving your speakers, so one amp handles the whole system. If you want more sub power than the fifth channel provides, run the four channels on your speakers and add a dedicated monoblock for the sub instead.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between a 5 channel and a 6 channel amp?\u003c\/h3\u003e\n\u003cp\u003eA 5 channel is four full-range channels plus a dedicated subwoofer channel. A 6 channel is six full-range channels. Five channels is built for a passive front stage plus a sub on one amp. Six channels is built for an active three-way front stage, with the sub on a separate amp. Five is the complete-system amp; six is the SQ amp.\u003c\/p\u003e\n\n\u003ch3\u003eDo these amps have DSP built in?\u003c\/h3\u003e\n\u003cp\u003eThe amps on this page do not, so an active build pairs them with a standalone DSP in the signal chain. If you want the amplifier and the processor in one box, look at the Goldhorn DSP amplifiers, which combine channel count and onboard processing on a single chassis.\u003c\/p\u003e\n\n\u003ch3\u003eAre these new with manufacturer warranty?\u003c\/h3\u003e\n\u003cp\u003eYes, unless the listing says otherwise.

That is not a missing feature, it is the design. In a modern sound quality build, crossover points, slopes, time alignment, and EQ all live in the DSP, where they belong. Analog filters in the amplifier would only add components to the signal path that the processor makes redundant. The Lanna takes the signal straight in, amplifies it, and stays out of the way.

There is usually enough power for the front and rear speakers, but what is left over for the subwoofer is an afterthought. The link1000.5plus fixes that. The four main channels deliver 75 watts RMS each at 4 ohms and 125 watts RMS each at 2 ohms, with any pair bridgeable to 250 watts at 4 ohms, while the dedicated subwoofer channel produces 300 watts RMS at 4 ohms and a robust 500 watts RMS at 2 ohms. That is enough for most subwoofer systems without adding a separate monoblock.\u003c\/p\u003e\n    \u003cp\u003eAll of it fits in an 11.9 by 5.5 by 1.65 inch chassis that mounts under a seat where a stack of separate amplifiers never could.\u003c\/p\u003e\n    \u003cdiv class=\"pls-power\"\u003e\n      \u003cdiv class=\"pls-power-cell\"\u003e\n\u003cspan class=\"num\"\u003e75W x 4\u003c\/span\u003e\u003cspan class=\"unit\"\u003eMains at 4 Ohms\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"pls-power-cell\"\u003e\n\u003cspan class=\"num\"\u003e125W x 4\u003c\/span\u003e\u003cspan class=\"unit\"\u003eMains at 2 Ohms\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"pls-power-cell\"\u003e\n\u003cspan class=\"num\"\u003e500W x 1\u003c\/span\u003e\u003cspan class=\"unit\"\u003eSub at 2 Ohms\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pls-section tint\"\u003e\n    \u003ch3\u003eCrossover Flexibility on Every Channel\u003c\/h3\u003e\n    \u003cp\u003eThe link1000.5plus gives each channel pair the filtering it actually needs. Channels 1 and 2 carry a variable high-pass crossover at 12dB per octave with a 1x\/10x multiplier, so they can protect front speakers in the normal range or shift up to drive tweeters directly in an active setup. Channels 3 and 4 add a full variable high-pass, band-pass, or low-pass crossover at 12dB per octave, flexible enough for rear fill, dedicated midrange, or midbass duty.\u003c\/p\u003e\n    \u003cp\u003eChannel 5 is where the bassFREQ processor lives. It combines a variable low-pass crossover at 24dB per octave, a variable subsonic filter at 24dB per octave, and an adjustable parametric EQ, so the subwoofer stage can be crossed cleanly, protected from over-excursion, and corrected for cabin resonance without any outboard processor.\u003c\/p\u003e\n    \u003cdiv class=\"pls-highlight\"\u003e\n      \u003cp\u003eBuilt-in summing accepts up to six channels of input, recombining the split signals that modern factory systems send to different speakers into a usable signal.

Adaptive OEM Load Technology and 40V input capability let it accept high-level signal directly from demanding factory amplifiers, and differential balanced inputs reject the noise that plagues OEM wiring. Auto turn-on works through DC-offset or audio signal detection, so no remote wire is required when one is not available, and it is Start\/Stop system compatible for vehicles that cut power at idle.\u003c\/p\u003e\n    \u003cp\u003eThe build matches the intent. A compact aluminum chassis with detachable mounting tabs supports multiple mounting orientations, Active Thermal Management holds output under sustained load, and 4-gauge power and ground terminals feed the current. Variable gain with a clip LED makes level matching precise, and the optional linkRC remote brings subwoofer level control to the front seat.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pls-grid\"\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eSubwoofer\u003c\/span\u003e\n      \u003ch4\u003eReal 500W Sub Channel\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003e300 watts at 4 ohms and 500 watts at 2 ohms, enough for most single-subwoofer systems without a separate monoblock.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eFront Stage\u003c\/span\u003e\n      \u003ch4\u003eCH 1\/2 HP with 1x\/10x\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eVariable high-pass at 12dB per octave with a 1x\/10x multiplier to filter full-range speakers or drive tweeters directly.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eMid Channels\u003c\/span\u003e\n      \u003ch4\u003eCH 3\/4 HP \/ BP \/ LP\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eFull high-pass, band-pass, or low-pass at 12dB per octave for rear fill, dedicated midrange, or midbass.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eProcessing\u003c\/span\u003e\n      \u003ch4\u003ebassFREQ on CH 5\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003e24dB low-pass crossover, 24dB subsonic filter, and adjustable parametric EQ for a tuned, protected subwoofer stage.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eSignal\u003c\/span\u003e\n      \u003ch4\u003eBuilt-In 6-Channel Summing\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eRecombines split factory signals into a usable feed internally, with no outboard summing processor needed.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"pls-card\"\u003e\n      \u003cspan class=\"pls-card-label\"\u003eIntegration\u003c\/span\u003e\n      \u003ch4\u003e40V Input + Adaptive OEM Load\u003c\/h4\u003e\n      \u003cdiv class=\"pls-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eAccepts high-level signal from demanding factory amplifiers with differential balanced inputs that reject noise.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"pls-cta\"\u003e\n    \u003ch3\u003eOne Amplifier, One Complete System\u003c\/h3\u003e\n    \u003cp\u003eFour main channels, a subwoofer channel with real power, and the crossover flexibility to tune all of it, in a footprint that fits under a seat.
