Amp...

[sschevy]

Ya i have 2 Alpine type S subs 12" dual 4 and a kicker 350.2 and my amp stopped working and caught fire. I was wondering if bc the amp is only putting out 350 bridge and the RMS with both subs put together is 600 will that cause my amp to fry like it did? Thats what the store i bought it from told me just wondering if someone could give me some help. Thanks

you probably fed the amp a load it couldnt handle. meaning the suba were wired down to 1ohm and the amp isnt 1ohm stable for example.

no i had them wired 4 ohm tested with ohm meter, and i have the right size fuse in my power wire matching what is rated on the amp. the amp had been shutting off here and there and the gain is not even half up and im not even driving it that hard but the dude i talked to said my subs total rms bridged was to large for my amps output. i duno any ideas guys??

The sub's power rating doesnt have an affect on output of the amp. The gain knob doesnt care if it was all the way up or not turned up at all. You shouldve match it with the signal that is coming out of the source (HU) so there is no clipping.

ps: subs cannot be bridged.

so pretty much what ur saying is if ur speakers rms is higher than ur amps output it cannot damage the amp??

Dude if you had that amp bridged and were running two 4 ohm subs you were not running it at 4ohms. I had that amp it is not stable below 4ohms bridged.

two dual 4 ohm speakers equal 4 ohms bridged so its better to just run each speaker to a individual channel then correct?

If you run 2 4ohm dvc subs wired correctly you could run one channel per sub and be at 2ohms per channel that amp can do that.

The amp wont "try harder" if you put a higher wattage sub on it if thats what your thinking.

alright thanks no thats what the guy i called said when i told him what happened and i didnt think that was true but that was all i was wanting to know if those subs and amp will work together i guess if i run 2 ohm on individual channels. Thanks for all your help.
