skittlesRgood Posted March 10, 2010 Report Share Posted March 10, 2010 hmm, probably the dmm im using. batts measured with dmm and voltage at the amp is measured with the xscorpion volt meter. ill test it when i get my box put back together. im still upgrading my batts so i can get more power later... if i choose to do that. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

notorious97200 Posted March 10, 2010 Report Share Posted March 10, 2010 I run a 1500 watts Sundown amp and 320 watts for my front speakers. I have 0 gauge wire from batt to the trunk and 0 ga for grounds (one for the battery, another for the 1500 w amp). All with stock alternator, stock battery. My voltage doesn't move when palying. Honestly, I may loose 0.1 less when I play at full tilt, comparing to the voltage with sound off. With the same system , but with just a 1000 w amp, it was even better : no difference at all playing, or not playing !!! Only the A/C give me big voltage drops ! black BMW X1 2.0 l 192 hp OEM head unit, Amplifiers : Audison AP 8.9 amp with integrated DSP and Ampere Audio 1200. Focal ES 100 K in front doors, and Dayton RS 180 for midbass under the front seats. 2 SSA DEMONS 10" subs, in a 2.6 ft3 ported box. SecondSkin Damplifier on front doors, and Luxury Liner Pro for the cargo area. Link to comment Share on other sites More sharing options...
kmalinich Posted March 10, 2010 Report Share Posted March 10, 2010 look we're not saying get a huge alt setup and we're not riding steve meade's dick ... its just a good idea to move up from stock on a multiple battery setup. the current demanded to charge the batteries as well as to run the amps is much greater on high performance batteries .. plus the audio system.. on 1.5kw? you need something. i've seen cars shut off because the audio system draws too much juice. i've seen amps melt things on the heatsinks cuz the thermal protection was shot.. all because of low voltage and shitty electrical. and i don't give a shit what anyone says.. i can hear voltage drop. when you've got a hifonics 2610 in a cavilier off of stock electrical pushing a 1 ohm load... shit breaks. thats why smart men upgrade and dumb kids break things. just my .02 Link to comment Share on other sites More sharing options...
Ray Posted March 10, 2010 Report Share Posted March 10, 2010 I like getting ALL the POWER I pay for. #1 1000watt rms amp cea rated @ 1000 @ 14.4v does roughly 750 @ 12v should have just bought a 750watt amp and ran the right electrical IMO So, do whatever you need to do to keep your voltage up at 14v PERIOD. Can you "get away with it"?? Yes..sure...absolutely. When you guys spend so much time, getting the best product for the cheapest price, why would you just half-ass you charging needs???

Marlo Stanfield Posted March 11, 2010 Report Share Posted March 11, 2010 With that vehicle it's not needed off that much power, but I would suggest the extra batt and big 3.. I used to run 3k daily in my old '06 Sonata(w/ the v6) and it was just fine with the big 3 + a Kinetik 1000 under hood / 2400 in back. Btw the amps weren't the most efficient either(gold model AB VFL150.1s). 1998 Ford Explorer Eddie Bauer... New setup, old ride... QX56 is staying stock til I get loud...

sabor Posted March 12, 2010 Report Share Posted March 12, 2010 stock should be fine for 1500 watts. You won't be pulling the 1500 all the time. Link to comment Share on other sites More sharing options...
