I have two alpine type s 10" subs, and I want to run them on a JL 250/1 mono amp. How do I got about doing so? I know how to set up and amp wiring kit and all that, just not sure how to wire the subs to the amp to get the best sound

You have two choices depending on the speaker impedance and the impedance that the amp is able to drive: Serial or parallel. If you hook the speakers in series, the load impedance that the amp sees is double that of a single speaker. If you hook the speakers in parallel, the load impedance that the amp see is half that of a single speaker. What is the speaker impedance and what load can the amp handle?

if you don't mind, just google
alpine type s 10 specs
jl 250 1 specs

That's something you should be doing.

haha, i did but reading that means nothing to me sorry so i was hoping someone who can read ohm description and watt output can tell me the best way to wire up my subs :\\

okay well the JL amp specs are:
250W RMS @ 1.5 ohms - 4 ohms
and the alpine type s 10:
Impedance 4 ohms

You can wire the speakers in parallel or in series. To be safe, I would wire them in series.

Take the positive output from the amp to the positive of the first sub in.
Take the negative terminal of the first sub to the positive of the second.
Take the negative of the second sub to the negative speaker terminal on the amp.
Voila! a series connection.
In parallel, all negative terminals (amp and speakers)are connected and then all positive terminals are connected.(amp and speakers)

Your amp is a very good amp and capable of and designed for operating into loads as low as 1.5 ohms. Definitely wire it in parallel.
If you wired it in series you would be presenting the amp with an 8 ohm load and you would not be getting maximum power from the amp.
This is how to wire it in parallel:
From the amp's + to 1st speaker + then to 2nd speaker +
From the amp's - to 1st speaker - then to 2nd speaker -

Although I agree with your recommendation (as I stated in my earlier response), in order for this amp to operate effectively with a 2 ohm load it will require a robust power supply (strong battery) and large gauge wiring (from the Crutchfield catalog: 8-gauge power and ground leads and a 30-amp fuse recommended wiring and hardware not included with amplifier). Based on the questions asked in this thread, I am not sure the OP has the required knowledge to understand what this means, nor the skills to implement it. Hopefully he will read some books to gain a working knowledge of basic electrical theory (impedance, ohms, current draw, wire gauge, etc.) before attempting such an installation or that he consigns it to someone with that knowledge and skill. I would hate to see him damage the amp and spealers, or worse, his car's electrical system, through an incorrect and inadequate installation.

haha, I was just unsure of the terms parrallel and series wiring.. and didn't understand how to achieve the best ohm load dude. I'm using 4 guage wiring for both power and ground and have a 75 amp fuse

I still have my doubts about the OP's level of understanding and knowledge. Oh, well. Not my problem, I guess.![]()
