8ohm speaker mono block amp question

[pghram1500]

All, I have an older 8ohm RF 10" sub. This sub is rated at 200RMS at 8ohm. What size amp will I need to handle this. Looking for quality but price conscious amp. This is for my daughter looking to just add mono block amp to handle one 10" in a box in trunk. Not sure on size because of speaker being 8ohm. Hoping to get under $100 amp for her but nothing that is total crap.

Thanks

Edit: adding additional data.

I actually have two of the same subs. Would I be better to wire both to lower the ohm down to 4. Still the question exist what amp size to adequately power both subs then. The subs are RF RFP-1810.

$100 is crap territory. More descent options would start at 150 like this one in the classified.

if u have 2 8 ohm subs yes 4 ohms is lots better either way u better off to go with a 2 channel amp bridged in this case, cheapest mono amp i'd recomend is ppi 1k like mine tested at 690rms @4 ohm so may do like 300-350 at 4 ohm it's decent amp but it's $159 or so.. u in the only situation that i recomend 2 channel fir sub and even low end at that., or if u lived here u could come try my autotek 1600 (probably does 200rms @ 4ohm maybe) u can get those about $79.. i can find u something (i do love to shop) but with that weird ohm man u maybe better to get a cheap package deal like ct sounds 12 and amp and box for $150., other pacages like that ain't bad for kid as long as u set gain low and tell them not to mess with amp.. https://www.amazon.com/dp/B01M3WW0UA/ref=twister_B01N7G2R1J?_encoding=UTF8&th=1

read my last reply ppi 600.2 is about $117 4 ohm should do 300rms or 600 if u use both subs i'd do that and if u ever get other new 4ohm dvc subs wire each to 8 ohm and bridge this to them same way (1 guy here with like probably $8-10k system has 4 of these in his truck)

id get a ppi 1000.1 or cab 1600.1 because its a small amount more with way more headroom for the future and itll retain its resale value

just keep the gain down, and make sure she wont turn the gain up because it will blow a sub with that low power handling and it will put a strain on your electrical

Yes you'll be far better at 4 ohm assuming you have the space for the two subs in a proper box. I hate to say it but you may just do better dropping 100$ into a modern woofer and working around that, you could keep the 8 ohm subs and use them for a home theater sub project or something. Virtually every amp you'll buy today, particularly on a budget just won't make squat for power into 4 ohms much less 8. Even trying to get good power into 2 ohm isn't budget friendly territory and limits your options.
