Great Sound Quality
I bought this amp on closeout. Got a great deal. I upgraded from a 90's Alpine 4x25w amp. I'm using the AA-75.4 to power some Kenwood 6.5" + 1" soft dome tweeters in the front doors and some 5.25" coax speakers in the rear doors of my 4Runner. I've had these speakers for a while and I'm now hearing things in songs that I haven't noticed before. This amp sounds super clear and balanced. Very open sound. It's paired up with an Aura Sound RPM 2150 Stage 2 powering a 10" sub in a bandpass enclosure. My system has never sounded better. I'm not using the crossovers in the amp. But, I could see how they would be useful. I find setting that stuff up inside the head unit to be way more convenient. I'd recommend this amp in a heartbeat.

Extremely Pleased!!!!
I only ordered the Ampere Audio AA-75.4, BUT I have to say Down4Sound knows how to do it right I've ordered from DroppinHrz and SSA and I was dissapointed with both the package was nicely boxed they took the time to read my requests to get package signed because it was circled. Got a nice looking shirt,volt meter ,lanyard ,a thank you signed by JP, and even a candy cane the amp was new not used which was an issue I had somewhere else. All these companies sell the same thing same price, but here there take care of you with extra things but truth be told I'm just happy how my product came MINT!!! I was waiting to see the condition and now that I'm super satisfied I'm going to order the Ampere Audio 3800.1 so I can strap!!
