That 44 watt amplifier happens to be a cheater amp /Zed Amp, and will produce an enormus amount of power than todays amplifiers, along with Quality/tdh, and db ratings.It will, and has pushed a pair of 400rms 15s with authority at 2ohms bridged...I have 2 of those amps for sale if youd like to buy one and try it out for yourselves.Or do some home work on Steze Mantz/Zed Audio, and find out just really where true power lyes, along with SQ.That subs sounds BA in that truck ,and hits beyond 135db, as my meter goes into error after 135.Not too shabby for 44 watts, and 1 ten in a simple Bazooka space saving/light weight enstallement, at a 2ohms load.And only 8.ga power supply was all needed to supply the old school SQ amps,As for my system/systems, they sound GREAT!ALL old school Zed Made amps, and discontinued power house (4,1000rms 2ooopk subs on 200watts slaved).My S h i t sounds just fine.Does everyone need to run at a 1ohm load these Days?And spend a Crap load on upgrading theyre electrical to achieve the true rms ,or stay stock and retrieve only a portion of the amplifiers rms power???//content.invisioncic.com/y282845/emoticons/awesome.gif.4430a219d9aaaa6cadc75e9290979dfb.gif I have been in car audio since 89, and have done just fine with all my systems, and even get complimented on my own installs, as well as doing others, and car audio shops have always asked who installed it, and how the hell can that amp be pushing those, and sound this FKN loud???//content.invisioncic.com/y282845/emoticons/boink.gif.91933e72f927f2cefc79aff02573090c.gif
