How much power can these subwoofers safely handle?

[plantinseeds]

I have two 12 inch Alpine Type R's SWR1242d, so the DVC 4 ohm version.

Specs are 500 rms/1500 peak

Just wondering how much power I can give them on a daily basis

I have a 1700 watt Soundstream Lil' Wonder monoblock amp to work with and the Type R's are in a ported enclosure.

Stock electrical, either 110 or 130 amp alternator.

the old scool r's can do 800rms easily

They'll take at least this everyday..they're rated at 600RMS, aren't they?

Alpines are durable. They'll survive at least 800w RMS of clean power daily.

Its box dependent...

Prefabricated ported box tuned to around 36 hz.. How do I determine if this amp puts out clean power or not? haha

Yeah I know... was a spur of the moment online purchase. I don't understand all of the hate with prefabricated ported boxes haha, mind giving me your opinion fellas?

Not usually well built, or built to spec for the sub being used especially when going ported.

If it's a prefeb sealed then it's not so bad. But they will take your amp just fine. Make sure you set your gains properly though. What HU do you have?

Most of the time ported boxes are much too small...

I've been looking into my own ported box, but the prefab should suffice until I get my paycheck, plus I need to find a simple box plan that will be perfect for two 12 inch Type R's.

The head unit is a JVC KD-g340 I believe?

Eh, you can try to get as clean power as you can.

I'm still waiting for someone to explain the difference with "clean power" which allows a woofer to handle more heat than the "dirty" power which somehow is bad?

IMO manufacturers rate speakers for a reason. 500W seems to be what Alpine considers "you'll never kill it with this" power and 1500 as "you'd better **** well know what you're doing and not do it long" power.

I'll probably go with 650 watts on each just to be safe.. The second Type R should arrive early this week. Can't wait to get the system started back up again!
