Sammitch0 Posted May 25, 2011 Report Share Posted May 25, 2011 I have a 90A alternator and a big brand new regular stock battery. I hold 14.4v when I first start it I can full tilt for most of the day and then it drops down to 13.5v then even longer it drops to about 12-12.5v. I run about 2000RMS with 4 channel and mono block. Would an XS 1200 in the rear clear this problem up a little? I do have big III 0 gauge knu conceptz all around. Also if I get a new amplifier say for example an m2a that does rated @ 12.5v would I get clipping if my system dropped to 12.5v? or does that not matter... Problem is my subwoofer heats up at 1500RMS I clamped my AP and it does 1456 @ 1 ohm clamped power at 14.4v (hooked it to my box DC 270xp and 2 bats) but Im guessing when I hit 13.5 or 12.5 Im losing alot of power and doing a lot of clipping. My subwoofer can handle 1600DAILY but its lucky o handle 1600 for minutes without getting to hot so I have to turn it back to like 1000rms to stay cool. What amplifiers can I run that'll do 1500RMS with my voltage drop and will the XS batteries help keep it up and be enough for 2kw I have a BRAND NEW 90A alternator and I have NO light dimming.

iKidwell Posted May 25, 2011 Report Share Posted May 25, 2011 don't even try an m2a on that...it does like 2x its rated power at 12.5...at 1 ohm theyve been known to do close to 2700..i ran my m2a with a d1200 in the back and a mechman alt and at idle i'd be in the low 13's..never saw 12's, but it won't clip as long as you set gains right. Quote c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old. i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer. 2003 Infiniti G35 Sport Sedan Build in Progress Link to comment Share on other sites More sharing options...
memphisBred Posted May 25, 2011 Report Share Posted May 25, 2011 Lol at 13 minute bump. Lots of amplifier companies have amps in the 1500 wRMS range. Also yes low voltage can cause clipping. My gain knobs clip indicator flashes if I am at full tilt and dip below 12.8ish to 12.5ish depending on the song.

Sammitch0 Posted May 25, 2011 Author Report Share Posted May 25, 2011 (edited) You guys dont seem to get what im asking... My AP is not even close to a high end amplifier it does rated but at 14.4v ONLY. My subwoofer warms up due to voltage drop to 13.5/12.5 right? cause of clipping. I have my AMP SET to 1500RMS on DMM i even set it a little under and it still heats up. I have everything set fine im not a noobie im just wondering WHAT amps will DO 1500RMS @ 13.5v or lower. so I can give my subwoofer 1500RMS without it clipping at lower voltage. I cannot afford an alternator right now so thats out of the question. Could I just get a Hifonics BRZ2400 and set it to 1500RMS and call it a day? will that work?

canderton01 Posted May 25, 2011 Report Share Posted May 25, 2011 look into Crescendo audio. I know a lot of their amps will do rated at 13.5-13.8 volts instead of 14.4 like a lot of other amps.

That's the type of responses im looking for can anyone give models/prices or links and inforamtion? I'm not trying to spend over $300 so that might be a big problem then again its only 1500RMS.
