Wiring 2 Dual Ohm Subs

[colt325e 10+ year member]

This guy at a car audio store said that i have to wire my two 15s (Dual 2 ohm) like this

because my amp is mono, but cant i just wire them separately like:

and have the subs going seperately into the amp at 1 ohm, or does it have to be at 2 ohm?

depends if your amp can handle a 0.5 ohm load. if not, wire like the first diagram above.

The possible impedance for 2 dual-2ohm subs is .5, 2, and 8 ohms. You can't wire it for 1 ohm.

What Im saying is if I wire them independently. Like wire one sub to 1 ohm, and the other sub to 1 ohm, so then id be running 2 positve and 2 negative wires to the amp. instead of 1 positive and 1 negative.

You still haven't described your amp. What model (specifically) is your amp?

You have a mono amp, so you have one positive and one negative output. You can't wire them independently to it. Wire them together at 2 ohm. It will be fine.

A lot of mono amps have a pair of outputs to allow for multiple speaker leads, but Colt, those terminals on your amp are actually the same connection - they're parallel to each other just inside the amp. Whether you wire both subs to one terminal or one sub per terminal the amp still sees 1/2 ohm. You're going to have to go with the 2 ohm configuration.

bx1500d, yeah actually this whole situation is theoretical because i already wired it to 2 ohm, because i found out my subs are only 300rms when they were listed at 600.

thanks.
