Amp rated higher thAn subs?
I'm not really into car audio but I came across a pretty good deal on some pioneers and an amp and installed them today (with help). The amp is 800w peak and 350w RMS and the subs are only rated at 150RMS... I want to know how to safely adjust the gain to get the max output from the subs without hurting them... We had the gain on the amp turned up half way and it sounded amazing but my friend said that it was too much so we turned them down...

Basically I wanna know how one would go about getting the right gain to the subs without burning them up, since the amp can put out more than twice the power that the subs are rated at...

Alright to get a perfect adjustment you would need a special tool to read the right amps, to also to mind you, you amp with put at different rates has you RPMs on your car goes up n down, to takes a good ear to adjust it right but there is really no "perfect" balance to where you can set it

I know there are special tools for this job but I am sure most people dont have that tool... basically how would you adjust it? I dont wanna blow the subs... how do i tell if im overworkig them? my freind said he smelled it getting too hot but i didnt smell it until my head was right in the sub... is there a way to use a standard multimeter to figure out wattage?

Yeah but also every sub is different, can you give me more information on the amp and subs

pioneer 6m-7300m amp 800 watt max 350w rms
2 pioneer ts-w301r 800w max 150w rms subs

subs are 4ohm if that matters

thank you for the quick replys

If you have (2) 150W subs wired in parallel then the total power the subs can handle is 300W @ 2 ohms. The amplifier is rated at 360W @ 2 ohms. You can have it turned up to 75% and still be safe. The subs will begin to distort and bottom out before you burn them out.

Depends on how old the subs and amp is, newer amps have built in fail safes to where the sub will send a little signal back before it blows and the amp will lower the power to it! I've ran two JL 12W6 off of a 1000/1 amp and those subs were really old but since the amp was newer it wouldn't blow the subs, and trust me! I TRIED haha and tried for 6 months till I gave up!

I think that mine might be that way because I have it turned up pretty far and it hits really hard for a minute or so then it doesn't hit as hard

Nathan21 11-17-2013 08:51 AM

Look for small rips or rates in the foam around your sub

n8mcd 11-17-2013 12:14 PM

I don't see any, they sound good it just seems like when I first turn them on they hit harder then after a few minutes they back off to a normal level

Maybe because they're cold and stiffer, then warm up become more flexible?

^ could be, I don't know much about sound systs
