Dan2427 Posted February 2, 2011 Author Report Share Posted February 2, 2011 I don't want to bash any company! Although I doubt anyone would listen to a SMD noob! But I figure I will for sure be goin with DC Power or Mechman now. Which was my initial thought, but like I said this guy was telling me his 240 amp alt did 230 or some shit at idle so that caught my eye and figured I'd give them a call. I like the warranty, I like that I can talk to the guy who makes the alts but I hate the thought of paying $700+ for an alt that I would have to make brackets for to fit!

Torres Posted February 2, 2011 Report Share Posted February 2, 2011 haha wow i would never buy from a company that said his alt did almost full power at idle. that's just stupid Quote Link to comment Share on other sites More sharing options...

soundman72 Posted February 2, 2011 Report Share Posted February 2, 2011 Most people can't hear a difference in volume change unless it gets to/or exceeds a 3db change. Now while this is a big difference to those who have witnessed it...keep in mind... if your vehicle is pulling 135db @ db drag... you (under perfect conditions) would gain 3db by doubling your power. So for however much the amp and wiring costs you, you've moved from 135 to 138db...the question is...is ONLY a 3db gain worth the time and money? VS say...a better box? A better design? A better woofer could make the same difference given efficiency ratings... All about how you want to go about it. Side note: with regards to doubling overall output...for those who don't recall....you must multiply your original power by x10. so 500w...turns into 5000w in order to double the output. (Keep in mind these calculations are based in a perfect world; other things will play into this) Quote Link to comment Share on other sites More sharing options...
Robert8252 Posted February 2, 2011 Report Share Posted February 2, 2011 A very very basic rule of car audio is: double the cone area gain 3dbs. Double the power gain 3dbs. That's a very generic idea but usually very true depending on the situation and actual power. But at the least to the ear another 4k will sound twice as loud toyou.

Neo_frog Posted February 4, 2011 Report Share Posted February 4, 2011 Did everybody miss the original point here? If he adds a second amp to his 1 amp/2 sub setup, chances are, he will hear very little difference in reproduction. Load distribution will be better across two amps and it will be more efficient, but he'll be halving the load (doubling impedance) on each amp yielding half the power from each. I'm assuming you're using D1s. So unless you're planning on running @ .5, you won't have a big difference. Or did I miss an important part of the story here?
