I'm new to car audio and could use some help upgrading the ELS system in my 07 RDX Tech. I'm hoping to get things done for roughly $500. I'd be fine with the OEM system if the OEM woofers weren't so low quality. My front door woofers are blown so at the very least I need to replace them. I’m open to buying used parts to save money but I’m not sure that’s a great idea for audio. I’m stuck on how to deal with the 2-ohm OEM speakers. Having read through posts here it looks like my options include:

1. Replace woofers with OEM speakers. Super easy, relatively cheap, speakers are 2 ohm as intended. Biggest downside is that the speakers aren’t great quality and may blow again and I could get much better speakers for not much more money.

2. Replace woofers with 4-ohm, coax speakers and not worry about 2 versus 4-ohm, or coax vs component, or OEM vs new crossovers. People on this site have done this. I’m guessing this is probably the most offensive option for audiophiles haha. I’m not a big fan of this option.

3. Buy 2-ohm components but don’t use the new crossovers. This is pretty easy, but there are very few 2-ohm speaker options, and this wouldn’t use the proper crossovers. I’m looking at these JBL GX600Cs:
4. Same as 3 but buy a signal processor to “undo” the OEM crossovers and use the proper crossovers designed for the new speakers. This doesn’t make a lot of sense to me -- if I’m determined to use the proper crossovers wouldn’t my money be better spent for a new amp…?

5. Replace OEM amp with a multi-channel aftermarket amp, which lets me use the proper crossovers for the new speakers, and allows me to go with 2 or 4 ohm. And there should be a pretty big jump in sound quality with the new amp. Downside is a big jump in costs versus just buying new speakers.

Finally, I happen to have a spare OEM amp. Would there be any sense in trying to add the second amp and splitting the work across two OEM amps?

Thanks in advance for any advice.
