A little help with sub OHM's

[skyguy]

I am replacing my Solo Baric 8" sub with Ztoolman's 10" sub. The audio specialist said to make sure the OHM's match my system. Ok, so not being an audio guy I'm not sure what to check or how to check. Any advice would be helpful.

Thanks in advance,

what amplifier are you using? thats going to determine what resistance the woofer needs to be.

Alpine PDX 4 1.50 Amp. Would this be plug n play?
Thanks in advance,

Skyguy,

From information on the Alpine website, your amp will handle either 2 ohm or 4ohm loads. Since the Earthquake is a single voice coil sub of 4 ohm, the amp will work fine as long as the wiring to the sub is correct.

Have a look at the .pdf for the amp on Alpine's website: http://www.alpine-usa.com which shows the correct wiring config for 3 channel operation. Your front speakers should be using channels 1 and 2 and most likely channels 3 and 4 are bridged for the sub.

You might need to make some gain adjustments at the amp due to subwoofer swap. If it's too quiet or being driven to distortion you can try to correct with the subwoofer output control of your headunit if so equipped. Better to correct at the amp though with the gain pots.

Hope this helps.

note that when 2 ohm its PER channel, NOT 3+4 bridged. thats 4 ohms.

The bottom line is you will be fine Skyguy. No problems whatsoever.

Thanks for the assurance. I feel much better about it. I like the Solo Baric sub but it just takes too much footwell space. I'll post pix when I get the Z's sub installed.
