How hook amp up to a oem integration SNI-15 line output convertor


The amp needs an RCA input to communicate with the head unit. SOLDER the wires that come out of the head unit for the front speakers to the SNI-15, making sure that the polarity and right/left is correct. Do this for the front and rear speakers if you have a 4 channel amp. Cut the wires if you add new speakers and run the new wire from the speakers or sub box directly to the amp, or skin back the wire insulation and tap on if you use the factory speakers :( then plug your RCA cable from the SNI-15 to the input side of the amp. Don't forget that most new cars have their own amp so you might have to locate it and bypass the speakers wires around it. Don't make a mess in case you have to put everything back to factory for resale. You can avoid all this by installing a new/modern head unit with built in RCA outputs for front, rear, and sub woofer. I hope this helps. Ray

Hello, can someone help me, i want to know how to connect the wires if i want to use 2 channel instead of 4. THANKS IN ADVANCE!!!!!!!!!!!!!


You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:
http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

How 2 bridage an alpine n a kenwood togethes


you cannot bridge them together. if they are bridgeable, you can bridge one amp to one speaker and the other amp to the other speaker. make sure not to go lower than the required ohm for each amp. also, you probably will get a different output wattage for each amp.

Can this power a subwoofer and what is the rms wattage


Hello crucible19,

The Alpine MRP-F240 is a 4-channel amp that outputs 40 watts RMS per channel. It is more suited for powering normal speakers, but since it is bridgeable, you could power a small sub by bridging 2 of the channels.

Hope this helps.

Subs have almost no sound coming from them


Hello meow_mix_666,

If you have tried different amps and different subs with the same result, I'd definitely suspect that you are not getting enough of an output signal from the head unit. Checking the RCA's and perhaps using a different set of preamp outs would be a good idea.

One other possibility that you may not have considered is to check the phasing. I've run into speakers that had the markings reversed and running the subs out-of-phase on a 4-channel bridged would make a huge difference in the bass.

Hope this helps.

My head unit has 1 set of preamp outputs can i conn. 4 speakers


Yes you can use a y to go to all four. Or you could bridge the four speakers wires onto the two outputs for 1 channel

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
