I have installes an amplifier (4 x 50WRMS) and I did as the following:
Bridged 2 50:s = 100 WRMS driving a subwoofer(MDS 370WRMS MAX)..
2 x Singles 50WRMS supplying 2 coaxial loudspeakers(Sony -Explode-45WRMS)
the problem is that I hear the engine noise when I play music..otherwise there is not any problems with the sound quality..

Re: Jensen Amplifier..4 x 50WRMS at 4 Ohms
This sounds like you need a ceramic noise suppression filter/ferrule on the Power line to the amp.
You should be able to get a suitable one from most car audio shops.
Hope this helps, please post again if you have trouble getting one :)

The wiring configuration is highly dependent on the amplifier being used. The subs can handle 250 Wrms each, so I would not recommend putting them in any configuration that results in power levels higher than 250 Wrms per sub.
This really depends on the setup you intend to create in your vehicle.
The Amplifer (amp) needs to be matched to the speakers you intend to run.
As a rule of thumb, the power of the amp shouldn't exceed the max. power of the speaker (this may damage your speaker). Instead, the amp's RMS output power should be at 75-100% of the speaker's RATED (RMS) input power. NOTE: this must NOT be confused with max power.
Ideally, you want to run each speaker with its own amp channel.
A subwoofer will usually require a hi-power single channel amp, or a 2 channel amp, bridged into 1 (to increase power output required for the sub).
Here are some examples in simpler terms:
1 channel (hi power) amp can run a subwoofer. 2 channel amp can run 2 speakers, or 1 sub (bridged). 4 channel amp can run 4 speakers, or a combination of 2 spkrs + 1 sub (bridged), or perhaps 2 subs (bridged).
You are correct, the amp will not support 2 ohms bridged. your best bet would probably be to have one voice coil on each channel. You could run them in parallel on one channel. but you will be getting the same power to each sub as if you put one on each channel. If you run them at 8 ohm bridged you will be getting less than 125 wrms per voice coil because of amp inefficiency at such a high resistance. It will sound cleaner also if you have one voice coil per channel.
If you are referring to the Kicker L5 solo-baric subwoofer, then an 800 watt peak amp will not blow even one of those subs. The L5 is capable of handling 1000 watts peak and 500 wrms. An 800 watt peak amp will usually have around 400 wrms. Underpowering the subwoofer will not hurt the amp or the sub(s).
your kicker cvr subwoofer should have a max power of 1600 watts therefore your amp is not too much for the sub because the p300-1 amplifier has a max output of 900 watts. if anything your amp would not be enough to produce max power out of your subwoofer. your sub should not produce an odor unless you have your amplifier bridged which doubles the watts pushed to your subwoofer and if that is the case your amp is pushing 1800 watts to a 1600 watt sub which could be causing it to fry or possibly blow soon. other than that if thats not the case there shouldnt be a problem.
400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power
In other words the amplifier won't blow these out now.
