wiring subs under the seat...

noire07 · 05-19-2008, 08:29 AM

This is probably a noob question but this is the first time installing a system.. I've got a 5 channel amp (PDX-5) and want to run two subs (sws8, 4ohm) from the one channel. If I run the wires parallel, it's going to lower the load to 2ohms. Would this be safe for the subs?
or if I run the wire series its going to raise the load to 8 ohms and make the output of the subs lower, right?

Any advice or help would be greatly appreciated. Those who put in 5 channel amps (or mono), how did you wire your two 4ohm subs?

The pdx-5 is 2 ohm stable so you are fine. Just wire them parallel (both positives to the positive and both negatives to the negative).
