SoCoDuster Posted September 28, 2012 Report Share Posted September 28, 2012 Alright Im still fairly new on the whole car audio thing, and i need some answers to a problem my friend has. He recently installed two p2 ten inch subs into his dakota sport. he has them running off of a 600w sony xplod amp im pretty sure. When he turns his volume past 22 somtimes 24 his subs shut off. Why? My first thought was the subs are to powerful for the amp but im not really sure. is there an easy fix? Link to comment Share on other sites More sharing options...
Sosebee Posted September 28, 2012 Report Share Posted September 28, 2012 Not enough voltage, which sends the amp into protect. How are the gains set?? You are probably sending a clipped signal with that Sony xplod amp 2005 Chevy Colorado Pioneer avic-x930bt Alpine pdx-m12 Alpine pdx-f4 Focal is 165 Focal ic 165 Sundown SA 15 D4 Kicker 0/1 OFC power wire Kicker 12 awg speaker wire XS Power D2400 DC Power 270 H/O Alt Link to comment Share on other sites More sharing options...
rocking.that.eclipse Posted September 28, 2012 Report Share Posted September 28, 2012 You could be hitting the protect on the amp because the impedence is to low Link to comment Share on other sites More sharing options...
soundstream15 Posted September 28, 2012 Report Share Posted September 28, 2012 Are the subs dual 4 or 2 He's running the amp below its impedence Could be bad ground as well Link to comment Share on other sites More sharing options...
Nikitaaa Posted September 28, 2012 Report Share Posted September 28, 2012 Make sure gains are not cranked up. 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw Link to comment Share on other sites More sharing options...
Tim Lam Posted September 28, 2012 Report Share Posted September 28, 2012 another possible reason could be the amp has clipping protection and shuts off. Link to comment Share on other sites More sharing options...

Is there a way to fix a clipped signal? turn the gain down. turn any equalizers down on the HU. get a line driver. get better RCA's lower/turn off bass boost.

Colin - STAPUFT Posted September 28, 2012 Report Share Posted September 28, 2012 These have been said already, but I would check things in this order. 1. Make sure the impedance isn't too low. The subs may be wired below what the amp is comfortable with. 2. Watch the voltage when he cranks it. Voltage could be low straining the amp and causing it to cut off. Amp have good size power wire and ground? Good clean ground? 3. Voltage from Head Unit may be too high / Clipping. Clipping will put the hurt on the amp and the subs. But- he could have bass or loudness or other settings cranked up on the head unit. Also, the head unit could be putting out a higher voltage through the RCAs than the amp is comfortable with. Are the gain and bass cranked on the amp? 12 - 12"s in the STAY PUFT 1989 Chevy Astro Build & Comment Log Un-Interrupted Build LogYouTube Channel Chevy Trailblazer 5.1 Dolby Digital DTS Install You have a beard of a mysterious sea captain.

conceptM Posted September 28, 2012 Report Share Posted September 28, 2012 I would only make 1 addition: good ground is very important. Make sure the ground of the motor to chassis isn't broken. BIG 3 isn't only a good option for heavier installs.
