Usually when I do a review on a product I will run it in one of the work vehicles for a week or two testing out different settings and getting a general feeling of how it functions, sometimes I even push the items to its limits. Writing a product review on the DD Audio M4a<\/strong> is slightly different in this case since I have been running two in ABTEC3<\/strong> for about a year now and have used them for everything from SPL<\/strong>, Ground-Pounding<\/strong> to just playing Ordinary Everyday Music.<\/strong><\/p>\n\n\n\n

The build quality of the M4a<\/strong> is just flawless, not just aesthetically either but also in how it preforms too! Over the last year I have powered many Sub-Woofer setups with the M4a<\/strong>, including: 4 x DD-510-D4\u2019s, 4 x DD-512-D4\u2019s, 1 x DD-9518-D1, 1 x DD-z18<\/strong> (the list goes on too) and has always provided plenty of power no matter what Ohms<\/strong> it was run at too!<\/p>\n\n\n\n

As stated before I don\u2019t just use a M4a<\/strong> for our SPL<\/strong> setup that has netted us 154.7dB Officially<\/strong> (We use 2 x M4a\u2019s<\/strong> for this) but I Daily ABTEC3<\/strong> driving a DD-9518-D1<\/strong> with a M4a @ .5 Ohm<\/strong> and it\u00a0absolutely loves it! Anybody that knows me knows I like my music LOUD<\/strong>, so LOUD<\/strong> that the windshield in the Toyota Vitz<\/strong> is usually flexing as I commute to and from ABTEC<\/strong> everyday!<\/p>\n\n\n\n

As far as sound quality goes the M4a<\/strong> lives up to the DD Audio<\/strong>\u00a0motto of True To The Source!<\/strong> I do understand an amplifier can\u2019t be judged on sound quality alone, but in my experience with the M4a<\/strong> and the Sub-Woofers I\u2019ve used with it have produced beautiful sounding Bass. Even down to the low 40Hz-20Hz<\/strong> that I love the most!<\/p>\n\n\n\n

What amazes me with the M4a<\/strong> is where most High-Output Amplifiers<\/strong> are rated at 14.4v<\/strong> or even higher, the M4a<\/strong> is still rated at 12-14.v<\/strong> which makes it ideal for everyday use. At 12v<\/strong> the M4a<\/strong> makes 5200w RMS @ 1 Ohm<\/strong>, at 14.4v<\/strong> it easily makes over 7000w RMS @ 1 Ohm<\/strong> and some people have even clamped their M4a\u2019s<\/strong> at just under 8000w RMS @ .5 Ohm<\/strong> on 14.4v<\/strong>!<\/p>\n\n\n\n
