Overall great amplifier!
I upgraded from an SFB-2000 to this SIA-3500, what an amazing difference. From the better crossover points to the power output. This beast does what it says it does. It is a must to have the electrical to support it, big 3, high output alternator, dual inputs with at least 2 AGMs or better.
I've ran the 600.1,1500.1,and 2k,awesome amps! Customer Service is the best! I recommend highly. Lots of power in a small package. Does rated power ++. Apex Audio is the source for Sundown Amps !!
Sounds great produces a lot of power and it’s really small
Awesome product. Great packaging. Quick service. Hand written "Thank-you". Will order again.
Big bang in a tiny shell. If you looking for big power and small price ticket then look no further and purchase now!!
Although this is a very powerful 2k amplifier. I realized it's stable down to 1ohm and my subs require a 2 ohm stable and it does not put out enough power to wake up my 2500 rms a peice subs. And I will need another or move up to the sfb5k . But in all it is well worth the money for a small all around system. Apex audio is a great source for my next amp .
Excellent product, strongest amp that actually does as advertised in power output, also come with a lot of cool little freebies from apex which was awesome. Thanks alot guys. Great store to purchase from
Great product. Work and looks flawless.
