1) If you bridge on a non bridged amp your sound will be horrible as they sine waves comming out of the two teminals will be different... I suggest removing the bridge. 2) The gain knob is to adjust when the amp will reach its max volume with respect to the sterio;s volume. 3) the LP filter is a Low Pass filter and its purpose is to eliminate the higher frequencies that do not sound all the well when played over subwoofers.

SOURCE: Alpine MRP-M650 : Power LED turns on but no sound

is the remote lead properly connected to the head unit? if the power led is on then the power cable and earth must be good, check the remote lead 2 your head unit first, if thats all good try looking at the amp to see whether theres a small switch to adjust the output going to the subs, if its very low or right off then nothing will be going through to the subs. if its on high and fine it only realy leaves the neg and pos inputs from the amp 2 the subs.

cheers, adam

SOURCE: want to bridge my alpine 3555 amp to run my sub.

I'm assuming this atleast a 2 channel amplifier all you need to do is hook the negative side of the speaker wire coming from the sub to the negative channel one. and the positive to another positive on channel 2. Should indicate on your amplifier channel one and two. most amps provide a diagram right on the amplifier over top of the speaker inputs. let me know if this helps.

SOURCE: Alpine mrp-m450 Amp won't stay on

Sounds to me like it might be the remote turn on because the first time i installed it, it did the same thing, and i found out that there is two blue wires coming out the stereo, one with a white stripe, i connected it to the blue wire, and it didnt work, then i connected it to the blue and white wire, and it worked. Well hope this solves your problem, goodluck.

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.

What is the best way to connect 4 speakers and a sub to a 4 channel amp.


I would connect the 4 speakers to channels 1-2 in stereo with high pass filter. Bridge the sub to channels 3-4.

Hi, I've just install an alpine power amp with JL 10inch subwoofer, everything seems to be working properly except for the subwoofer


If you have the RCA's running from the head unit to the amp, and the speaker wires running to the speakers then you have it hooked up right. Now If you still don't have any sound then you need to look at the amp to make sure that you have a green light. Still I would use 8 or 10 gauge power wire and then the same for the ground wire, make sure that you have a good ground.

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

Amp on but no sound from subs


Make sure that you have a good set of RCA cables. Then make sure that you have 14 gauge speaker wire. As for amp make sure that you use 8 or 10 gauge wire. Make sure you have a good GROUND.

Alpine 250


And theres your problem. You can't run 3 speakers on it at once. BIG NO-NO! It can only have 2 ohms or more on each channel or 4 on the bridge. Three speakers is gonna be WAAAAYYYYY below that. You need to correct it ASAP, or it's ALL gona blow.
