How do I stop blowing my subs?

ok so then you dont know how to properly set your gains i take it. the old or new type r's

By low do you mean on the .2v side?

Lol I was JUST thinking about that. He might have gotten confused.

Yes. 2v side my h/u at 15vthe constant and the new type r's yeah 1000I rms rated

.2 is all the way up

0.2v means max on the amp. It's in relation to the output voltage of the headunit. Meaning that the output voltage of the headunit is at 0.2v, so you match the preout voltage to the input voltage (gain). You need to check the RCA's with a DMM and find what the output voltage is of the H/U and match it with the input voltage (gain) on the amplifier.

Also since, mostly likely, you don't know what you're doing, I'd suggest turning the bass boost all the way down (0 db) and not tamper with it until you do some reading and find out what all the settings on your amplifier mean and how they function.

What's weird is it works perfectly at lower volumes still its just when I turn it up it sounds like a ruler is being slapped against my rear window

Watch this in its entirety.


Do this every time you install a speaker or sub.

Thank me later

clipped to shit

Thought .2 was the lowest I don't remember the numbers exactly but its turned max lowest to the left which is on low gain. I just don't recall the numbers because im driving atm

At low volume your H/U's output voltage is low, when you turn the volume up, output voltage goes up. If it goes past 0.2v (which obviously it did) then that's clipping. That noise you hear is distortion, distortion is a sign of clipping, clipping causes heat build up, heat causes death of your equipment.

That is INPUT sensitivity man.

Its supposed to be the HIGHEST value that your deck gives the amp.

Low would show a higher voltage i.e. 5v or in most cases 6v. The gain needs to match the headunit's max unclipped output voltage and nothing higher.

EDIT: Example, if you check your H/U's output voltage and it reads 3.4v, then you want to turn the dial at or a tad above 3.4v on the gain of the amplifier. Anything lower than 3.4v will be considered clipping.

Installing speakers isn't like plugging in a toaster. You have to be somewhat educated on how to set things up before you begin. Not trying to make you feel bad, its just reality.

If you are willing to learn, then great.

If you are not willing to learn, go to an installer and have it done right.
