loosing power
Tuesday, May 12, 2009 9:15 PM
hey guys i am hoping you can help me with a power loss issue i am experiencing.
I have a basic Alpine deck with sony xplode speakers hooked up for speakers at factory size. I also have a 1000watt pyramid pb448x amp hooked up to two subs, which i believe are planet audio 500w rms and 600w peak. when i am hitting hard bass the amp tends to pop into protect mode, or the whole system, deck and all shuts off and comes back on. I have checked battery and ground connections and all seems well, the amp will also blow fuses, and the two bottom red ports don't seem to work when in bridged mode. I am wondering if the big three upgrade would work to fix this problem, or if i may need a capacitor to make up for the delay in the battery power, btw this system is in a 99 cavalier 2.2l.

If by big three upgrade you mean amp sub and speakers then yes.

You have a bunch of very weak links in your system (and by that I mean you own crap products), one of them is bound to fail yesterday.

That said, protect mode:
-Gain too high, try turning it down to a moderate level, you're probably throwing it because of overheating.
-Ground: Make sure it is the same size or bigger than your power wire and is hooked to CLEAN PAINTLESS METAL.
-Impedance of Subs: If it's too low, an amp that bad will likely not go into 'impedance protect mode' but will just run until it heats up and goes into thermal protect.

If the whole system is turning off it means you're dipping below 11V, which is not only bad for your stereo but for your battery and basically every electrical circuit in your car.

I suspect, based on your choice of product that your gain is too high.

i will try turning that down, and as for your opinion that my products are crap, well you are mistaken. they sound clear in my car and clean with no interference, no distortion and no whine. Pyramid is an old school audio company that is known for quality amps that produce clean and crisp sound with little to no distortion. By big three i meant the big three wires off the battery as in the ground, alternator and fuse box wires

Pyramid is essentially the whipping boy of the whole car audio community,
Xplod is notorious for pooping out after ridiculously short lifespans,
Planet Audio is affectionately dubbed "Walmart Audio".

I'm not alone on this.

Brad is right
The audio brands you have a pretty much all walmart generic crap. Things like that don't tend to last at all.

Pyramid and Lanzar may have been good back in the day but now it's the whole cheap parts and big numbers on a sticker...



Do the Big 3 no matter what. That is:
Engine to ground.
Alt + to Batt +
Batt - to ground

I'm going to do mine in 1/0 here soon.

I thought my Pyramid was awesome. Until I cooked the left channel. Then I got a real amp. It sounds better now.

What ohm load are your subs wired at? It really sounds a lot like what my Pyramid did when I would put it to 2 ohms in bridged. I would crank it and for ten seconds or so it would hit nice then pop goes the fuses.That amp is not stable below 4 ohms in bridged.

mine is an old skool one that when bridged is in two ohm and the subs are 2 ohm as well. And yeahh i agree the xplodes are cheap, they blow if you run bass through them easily, but i dont, thatswhat subs are for and i have been running this system for two years, with the amp and a rockford 12inch sub, only recently have i installed the two subs, and they pound hard with no issue, and i have never had problems with planet audio, if tuned properly.

I had a PB1010GX. I honestly doubt that thing is 2 ohm stable in anything besides 4 channel mode. Trust me. Rewire to a higher ohm and itll be fine and dandy. Whats the VC configuration for the subs?

Edit: It also isnt old skool if its still for sale on the Pyramid website. The big purple paperweight in my room is older than yours.

Pyramid is/was terrible. Lanzar is another story though.
