View Full Version : Why am I smelling voice coil?

05-04-2009, 04:36 PM
So I got a new amp to solve a previous tuning problem with my speakers. I have 2 6x9's, (2) 5 1/4's and (2) 6.5 components.

I got an Alpine MRV 450, 5 channel amp to run them. The 6x9's are hooked up as the sub channel.

The speakers are all CDT EF series. They are all rated 165 watts RMS. The amp is rated 50x4 + the sub channel.

The problem is with the components. I set the deck to an output freq. of 150 hz, tuned the crossovers on the amp to 150 hz, turned the deck to a volume setting of 30 out of 35 to prevent clipping, and turned the gains about 3/4 of the way up on the amp. The speakers are not distorting or over bassing.

If I leave it turned up for a while, I smell voice coil overheating. The amp is not putting out enough power to overdrive the speakers (50w vs. 165w), and the power seems very clean.

whats up?

maybe your speakers arent accurately rated.
maybe your amp is over rated

clipping is probaly your answert ho

hey Booneville, try turning your amps xover off.
only use the decks xover,then turn your gains down to see if that helps.
so i guess your'e useing only two of the channels of the amp two power those comps, if you underpower a speaker you can clip them, try bridging the amp for more power then adjust your gains from there, make sure you aren't useing any basss boost.

The EF series wasn't that great to begin with IMO. I should know, i've got a set in my corvette :crap:

just turn down the bass boost if you've got it on.
