Amp to Sub Wiring Advice

I suddenly had a panic today that the Pioneer GM-D1004 Amp I bought to run my Infinity component speakers may be too much for them to cope with, as I’m struggling to find any specs for the 5.25” Pioneer 500cs speakers (Mids/tweeters).

I’ve attached the Amp spec sheet, can someone tell me what the minimum/ideal speaker spec would work?

thanks

Looks like 45w @ 4 ohm is what that amp is rated for. You may need to double check your component model numbers because earlier in the thread you said Infinity 600CS (Which doesn't exist) and now you're saying Pioneer 500CS (which also doesn't exist) AFAICT. Infinity 6000CS 6.5" or 5030CS 5.25's.

The speakers are proper old school (as is the car) but they are in good condition and seem to be well made. There are no spec details marked on the speakers, this is the best info I’ve found on the net.

I started the audio upgrade only intending to replace the head unit but I’ve got a bit carried away now with the interior of the car stripped out so I can properly mount, sound deaden and seal the speakers. I’m now wondering whether these component speakers will work okay or if I should replace them. I don’t want to blow a load of money on new speakers but if I can find some decent spec used replacements I may be tempted.

With the power capacity listed, I'm going to assume that's max wattage so 37.5W RMS. Based on that as long as you set your gain correctly you should be fine. There are plenty of speakers in the 45W range in all comes down to what you want to spend money on.

Thanks I think I’ll try them and see how they sound.

Saying that I've started researching component speakers, looking around at used sets for sale, would these be a good choice?

Hertz Energy ESK 165.5 - used in good working order £75

Focal K2 Power 165 KR2 - used, current bid £50, what would these be worth?
