1 ohm sub on a 2 ohm amp

I'm new to this forum. This is my first question here.

I have an old 1967 Ford Falcon with very limited space for a sub due to other characteristics on the car build.

Presently I have a system with only a Pioneer head unit and speakers, no amp.

It sounds good for what it is. I have 2 6X9 Kicker speakers in the rear deck and I added a 6 1/2" dual voice coil woofer in between them.

Yes I know this isn't the proper way to do things. Remember my statement about limited space? OK. here is my question area.

Since I can only fit a 6 1/2" sub in this car (which can't be very deep as I'm limited to mounting depth) I started searching for a replacement speaker for my center POS woofer. Yes I can fit a SMALL amp in here for the sub. I found a Kicker 6 3/4"" sub model 10CVT651

This is a sub designed for free air mounting with a shallow depth. Exactly what I need for this application. It is a 1 ohm sub.

I already have a 2 ohm amp.

My question is how can I increase the impedance of the sub from 1 ohm to 2 ohms so i don't blow the amp?

I know the obvious response is to hook 2 of the 1 ohm speakers in series but remember my limited space requirements? I can't do that.

Is it as simple as wiring a 1 ohm resistor in series with a speaker lead?

Look, I'm not trying to rattle the house windows when I drive by. I'm not trying to win and competitions. I just want a little more bass than my current set up. I fully know and understand a 6 3/4" sub isn't going to put out much but I also know it will sound better than no amp/sub at all.

My other choice would be a flat 8" powered ready built sub I can slip under the front seat. i haven't heard any good reports on those though...

What can I do with a 1 ohm sub and a 2 ohm amp ? (Besides buy a 1 ohm amp).

Sorry to say but your best and only real option is to either get a woofer that is 2ohms or more. Or an amp that is stable at 1ohm.

Wiring a resistor in series can create some issue. Technically it will be a final 2ohm load but the resistor is not reactive like the woofer. The resistor will heat up.
