The A1500.4 is a True Dual Stereo Design providing better stereo separation and imaging as compared to traditional stereo amplifiers - the chassis being the only thing common between channels. In an effort to provide the very best signal to noise ratio and lowest distortion possible, 109 dB (A-weighted) and <0.027% THD+N the amplifier utilizes a Mirror Image Design with positive and negative output signals of each channel generated using identically mirrored circuitry. Each of the two channels is also a mirror image of the other. A1500.4 operates the current amplifier devices in class A/B operation and the voltage amplifier devices in pure balanced Class A mode offering a realism and truth to the source never before available from a mobile power amplifier.

From a design standpoint, the A1500.4 utilizes separate PCBs for the voltage amplification stage (and each of the 4 channels has its own) and current amplification stage to maximize the signal to noise ratio so that it's dead silent. It has been designed from the ground up around the highest quality components available at any cost, including; Nichicon Fine Gold™ capacitors, Nichicon Muse™ audio capacitors, (8) On-Semiconductor complementary bipolar junction transistors per output section per channel, Burr Brown Op-amp and non-inductive resistors, all assembled on 4-layer heavy copper PCBs! Its dual stereo channels can be wired as two single channels with double the output voltage for applications where high power is required. Finally, it includes two pair of gorgeous LED output meters to indicate actual amplifier power for each of the 4 channels as well being used for self diagnostics during a fault condition.

Collected installed over 1000 amps this is the best solid state amp I've tried

Only rivaled by audio wave cr class a series maybe this is the best amp I have ever tried for sq very much like a good home amp thus was designed by Tony and tweaked by Japanese as he said in his video if you have the money and are really into sq for car audio and gave great speakers dsp and head units and electrical 0 Guage and extra batteries etc then you will hear what I hear and know this is one of the best car audio amps ever made imho the list if Amps I own or have tried is into 1000 currently I own mpz studio amp venti audiowave celestra steg mc50 phass mcc602tm etc

What dreams are made of

For reals this things what dreams are made of, I know becsuse that’s where I own it haha if only I could make the dream a reality!

Copious amounts of mediocrity

When I design an amp... I think to myself, what will make people think this is cutting edge... then it dawns on me... . Think of a reasonable MSRP to a factor of 4-5... I know, I'm amazing... Thanks. Tell you're friends about me.

serious achievement for mobile audio amplification

I can honestly say that its a large advancement compared to the competition. the idea is from old school thinking ...but the implementation is nothing less than stellar. And concidering its an sq amp that has voltage and current abilities of Spl amplifiers ....its the ONLY ANSWER for those tired of excuses and needs a REAL amplifier. This is it ..
