10 inch type r sun with jl amp

So i have a 10inch type r sub right now with a 650w alpine amp n its not pushing to where i want it so i was going to try out my friends 1000w jl black series amp. Is it even safe to run the jl amp on the type r sub? And i dont plan on blowing up the sub just wanted a high wattage amp for a bit more bass

Is it wired as a two ohm or a one ohm? The type r can handle up to 1000 RMS watts. The JL can produce that with the correct wiring.

If it is the slash series amp then the it should give out 1200 RMS at whatever ohm you wire your sub down to.

Its wired to 1ohms right now. I'm afraid my sub will blow since the amp is running at a constant 3ohms. Its not a slash series

couple things, the alpine can handle 1000 watts no problem. second the JL slash amps, they use a special technology, RIPS, that allows them to put out the same wattage over 1.5,2,3,4 ohms. so if your sub is wired to 1 ohms, the amp will not see this constant 3 ohms your mentioning....
also regarding the 1000 watts, there are many factors to those numbers, volume, music type, and voltage. you would need to put volume right before clipping, and have the proper amount of power to reach 1000 watts. Also your music choice will have some play in reaching the 1000 watts....
sorry to ramble on and on

You would need to test the setup at varying frequencies at the highest volume level before clipping on your stereo, tune the amp to 1000w if not 950 to keep the sub cooler, then confirm with a clipping indicator like the smd-1 to make site the signal is going through clean. I would test this on various songs and test tones before leaving it as a set rig to ensure no clipping. The difference in sound between 800w and 1000w is minimal, the difference in clipping or overheating on the subwoofer is the thin line between max output and a blown speaker however. Make sure to take into account manufacturing defects and whether your car is idling or only powered on when you do this though.

Here's a tip on how to set the level on your amp. If your amp is setup correctly, your sub shouldn't blow the sub unless you max out the volume or something or do something crazy.

The Type R subs can handle good power. I've put a Kicker 1200.1 to a 12: Type R and it handled it really well.

You should find out how he has it wired. you have 2 options: series (4ohms) or parallel (1ohm).
you should wire it for 4 ohms, because technically the JL amp's minimum impedance is 1.5ohms.

a DMM is a good starting point to set gains, but unless you have a Fluke DMM 120 series or higher your still guessing.

also the OP has a 10" type-r. the 12" type r has a higher power handling capability

by the way thats a good point in order to increase sound levels by 3db you need double the power... so you wont see a HUGE difference in sound levels.

3db is barely pervicevable, although anytime "db" gain is mentioned it is assumed that more is better. Sometimes it needs to be matched to the rest of the system, especially if you have stock speakers or unamplified door and rear speakers.
We will need to know which Type-R you have though, depending on the year it will be rated for 500, 600, or 1000w. The new ones at 1000w are very durable, the older 600 had some issues when going above 550.
There are also dual 2 and dual 4 ohm configurations, is there any chance you have the box, or can pull the sub out to grab a part number?

Otherwise a picture of the cone and an ohm reading on the leads from the box can help us better determine the model and capabilities of what you have.
