Wiring question
Got my goods, so Im going to try to get it all hooked up before it gets to cold out.
My only question at this point is wiring my two subs.
I want to wire them in series, but am unsure what exactly that means.
Any help is appreciated.

I'm assuming that when you say you are wiring them in series you are running them off a single channel or sub output. Your amp should have one configuration to run in stereo, and one configuration to run mono or bridged. Use the mono or bridged configuration on the amp. Be sure that you have the correct polarity going to the correct terminals on the speakers. That is red to red and blk to blk. Then all you have to do is run two sets of wires from amp to speakers. But run them off the same terminals. By doing this you will have the same wattage running to both subs off the same channel.

Wiring question
for a series connection u would want to run a positive from the amp to the sub, then connect the negative to the positive to the other sub, then connect the negative on the 2nd sub to the negative to the negative to the amp like this:
amp +-----+(sub 1)-
]
amp -=====-(sub 2)+
amp +-----+(sub 1)-
]
amp -=====-(sub 2)+

Wiring question
Wiring your subs in series will double the impedence eg. 2 4 ohm subs will now have an impedence of 8 ohms. + sub 1 to + on amp - sub 1 to + sub 2 - sub 2 - on amp. If you have a two chanel amp to obtain the most bang for your buck you would get two dual 4 ohm voice coil subs wire the two voice coils on each subs paralell which would now make the subs 2 ohms which on most amps increases the output by 50% or more, then hook the left subs + and - to the left amp chanel and vice versa on the right sub and right chanel or the other option would be two 2 ohm subs wired in series which would make them 4 ohms and run the amp in bridged mono, since most amps can't run less than a 4 ohm load in bridged mono or just get two 2 ohm subs and hook them to their left and right amp terminals respectively. Before I start rambling to much what exactly did you get for an amp and subs?

Wiring question
if your wiring in a series(im assuming with two 4ohm subs)you want to first of all make sure your amp is 2ohm stable so that it doesnt overheat. as for wiring, bridge the amp and run the the speaker wire to one teminal(just to keep everything clean). inside the box you need to bridge the subs pos. to pos. and neg. to neg. and run the same from the terminal to one sub. also use an electronic crossover with bass boost to filter all voices and raise the voltage to the amp and therefore making the sound more loud & clear. also use the appropriate wiring, at least 10ga. and ground it to the frame. with that you shouldnt have any problems

I ended up with two Rockford Fosgate HX2 RFD2210 10" Dual4-Ohm subs,
and a Rockford Fosgate punch 700s, (700 watts RMS x 1 at 4 ohms in bridged mode)
I know it's not the best stuff out there but like I said at the beginnig, I didn't want a competition system, It's only a regular cab so space is a problem. Also I thought it was a good deal at $350 cash and carry.
So wiring in a series would be amp pos to pos on sub , neg on sub to pos on next sub , neg on that sub to neg on amp?
Just don't want to fry anything.
Thanks for all the help!

[updated:LAST EDITED ON 14-Oct-02 AT 11:53 AM (EST)]You would want to wire the each subs voice coils in series to obtain 8 ohms then paralell the 2 subs to obtain 4 ohms if you are going to run the amp in bridged mono. If you are going to use it in stereo mode wire the voice coils on the subs paralell to obtain 2 ohms then run the + and - wires from the subs to the left and right chanels on the amp and you shouldn't have any problems, to be certain if the impedence is correct you can use a digital ohm meter to double check. The way the subs are wired as described in your last post would make an 8 ohm load which would be correct if you are going to run 2 subs in bridged mono.

Thanks again, that will be next weeks project. Just got done installing my other amp the "right" way.
It was flopping around behind the seat for the last 2 months.
I ended up putting it under my middle seat.
It didn't seem to produce that much heat before, so I figure it should be ok under there.
