First thing first does your 4 cahnnel amp match mate with your rf twelves? if it is try to bridge them. but make sure to adjust the gain to the lowest range as possible. tune your system and match the desired range for your bass and mids.

How do I hook up my inside speakers and sub's to


if setup 4 channel amp with low pass filter for the sub channel and other 2 channels for speakers with no filter, some amp you can use amp as 3 way if one or two subs, bridging output will give you more power for the sub. be aware that bridging 2x4ohm subs will give you 2 ohms and potentially damage the amp.

Looking for info on how to hook up sub to this amp thunder4160


Hi, you have two choices for hooking up a sub to the 4160 amp. You can either connect your sub to one of the two available channels, or if the amp supports it, you can bridge channels 3 and 4 to get increased power to your sub. You have a 4 channel amp - channel 1 and 2 go to your 3-way speakers up front, which leaves channel 3 and 4 available for your sub.

I have two 12 rockford fosgates p3 hooked up to and 350.2 kicker amp i just got them so i hooked them up and my amp will keep turning on and off


How may ohms are the p3's and how are they hooked up? Some amps won't handle less than 4 ohms bridged. Try running one sub to each amp channel.
Also check power and ground connections.
Useing too small of wire for power, ground can cause the same problem.

How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

I was given a kenwood kac742, what do i have to do to hook up 2 subs to it tom


You need:
1) 2 4-ohm subs
2) Appropriate enclosure
3) Amp wiring kit with RCA's

Connect each sub to a separate channel and set both mode switches to "MONO" (center position). In 2-channel mode, this amp is only rated at 80 Watts RMS, so you need relatively small and efficient subs. I'd say nothing bigger than 8" or perhaps 10". Rockford-Fosgate P1S48 (8") and R1S410 (10") will work OK with 50-150 watts RMS. Some others will also.

Kole amp in protect mode?


Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

I have a rockford fosgate p250.2 amp hooked up to two 12' subs but the amp is not powering on... instead the protect light is on and im not sure if its because its so cold outside... please help and thank...


Remove the load from the amplifier (subs) and the RCAs
Retry.
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s)
125 Watt - 2 Ohm - 2 channel(s)
250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load.
If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.

How many speakers can I use?


Hi,
This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

Good luck

ONE CHANNEL NOT WORKING


Please don't take offense, but some tips on submitting problems on Fixya:
  • Resist the urge to use all capital letters. Reserve them for frustrating yells :).
  • Use a period or two. It's very hard to read without them.
The easier to read, the better responses you'll get!
Anyway, back to the issue at hand.....

Definitely get a handle on the gain adjustment. Both channels should start with a gain at the 50% point. Also, you can try bridging the amp ("+" speaker outputs tied together, "-" speaker outputs tied together) and run the full 800W into the single 10" sub, but that is going to depend on what your sub is rated to handle.

The only other thing I can recommend is call around to a couple stereo shops and see if anyone can test the amp for output power. That'll verify whether there's really a problem on the one channel.
