Contour Enthusiasts Group Archives Forums Modifications Audio Infinity blown speakers (WHY)

Hi guys,

I have this setup a pioneer 6200 head unit with infinity 572.1 kappa speakers and a rockford amp 75rms. The infinity speakers are rated for 70 rms and 140 peak so they should be able to handle the power fine. But the other day I found that the woofer part of the speakers on the passenger side of the car are blown, both of them. I find it odd that one side of the car blew and not like the front set or the back set. Could this have been a wiring problem of something that needs to be checked regarding teh install.

Or do I need to set the crossover on the amp to now block out some of the lows so I dont blow them again because I had both hi and low going to the speakers.
Just dont want to put new ones in and blow them agian too.

Thanks Brian

Depends on how loud you like to play your stereo. If you like it loud that is most likely the culprit, try using a crossover. It is strange that the pass. side blew and not the other. As with any stereo problem it is usually better to check any connections/wiring first to eliminate that cause. If wiring is fine it could have been pushing the speaker too hard or simply a defective speaker. You have a few places to look at to be sure of the problem. Good Luck.

Amps can fail in such a way that they send DC voltage to the speakers. In that case, the bass speakers voice coil heats up til failure. The mid and high speakers are protected from this by their crossover capacitors. I used to repair car amps and have seen this happen a few times. You can test for DC voltage with a volt meter. Should read near zero.
