Need help converting a car subwoofer system to work as a home audio sub

[js3]

I have a spare car audio subwoofer enclosure with (3) blown 10" subs in it.

I also have a main home audio receiver and a spare home audio receiver. The main audio receiver has a pre-subwoofer output.

My desire is to:
(1) Replace the damaged subwoofers
(2) Use the main receiver's pre-sub out (to get the isolated low-frequency signal) and go into any input (ie: CD) of my spare home audio receiver, and then wire the subs to the Left or Right speaker output on the spare amp (or bridge them?)

Based on the limited research I've done online, I believe this is "safe" to do (ie: the amplifier should be able to power all 3 subs since it is dedicated to only the subs, and not get over heated), and I believe this will also give me the capability to use the spare amp to independently control the volume of the subs.

I would love to get an audio expert's thoughts on what I've proposed, and/or a link to a wiring diagram that I can refer to in terms of how to safely wire the subs so that I am able to match ohms (ie: series vs. parallel and bridge or mono from spare amp to subs).

Concerns:
1. Most subs I see online are 4 ohms, but my receiver is 8 ohms. I believe this can be solved based on how I wire the system.

2. Do I need to consider single-voice coil subs vs. dual voice coil subs?

Thanks!

Your avr isn't a good sub amp, and not likely going to like low impedance loads let alone demands of subs in general, and likely isn't suitable for bridging either. Your sub driver/box combo may be useless in large rooms like a home compared to a small compartment as in a car. Post specific make/model of your receivers and details of your sub drivers/box. Most at best likely you need to be looking at a separate power amp for your subs, but first need to determine if they're worth considering for your room at home.

This plan is a total waste of time and money.

Car sub's usually don't sound as good in a home theater setup, however, if you're set on doing this, your best bet would be using a pro audio amp, since it can handle the low impedance, and connecting it to the sub out on the receiver. A regular HT amp or receiver would likely be destroyed by heat from the kind of low impedance used in car subs.

If all of the drivers are blown and need to be replaced you should really just start over and build a sub with a new box, driver, and amp. No need to use used parts that weren't made for the job.

By the time you replace the three damaged subs, you could have bought a quality driver and basic flat pack cabinet from Parts Express along with a plate amp. The bright side of all of this is you already have a receiver with a sub out.

I'd personally rather throw $100 bucks away on the sub in the link, then to invest the time and money into that project. Be far better to just save for a better sub while running the Yamaha into the ground imho.
