Question about iLO XM-MP3-CD Car Stereo

1 Answer

Amp? I have a 4 channel alpine amp running a pair of component speakers (6 1/2 and 1") and a pair of 4x6 plate speakers. A separate amp runs the subs. At anything higher than low volume the highs cut out every few seconds and then come back on. It happens when playing the radio, cds, or thumb drives in the USB. It worked fine for a couple mounths. Now I have problems. Any help would be appreciated. Thanks

Make certain that each ouput channel from the unit is driving no more that 4 ohms each. If you have more than one speaker attached to an output then be sure they are wired in series NOT parallel. Two 4 ohm speakers in series is an 8 ohm load and the same two speakers in parallel is a 2 ohm load. If the speakers are dual voice coils then you must treat each voice coil as if it were another speaker when it comes to wiring.

    If your speaker loads are correct then you probably have a blown amp. Good luck.

I have an alpine mrv-f307 4/3/2 channel. I have it hooked up to 2 12in Kenwood subs. Right now standard 2 channel each sub having their own. I heard doing a series hook up and bridging the subs to the amp ...


Bridging an amplifier refers to combining the power of two channels to run one speaker at higher power. If it is wired correctly, your amplifier is running with 4 channels bridged into 2 speakers now.

I've just been given a pair of working Mission 780 speakers. There are 4 connecters on each speaker and 2 brass plates linking the left inputs to each other and the same with the right ones. What's the...


Do not remove the brass plates! These work as a bridge between the connections, making them a universal speaker. You only need one input. The other input should say "Bridge", which is an output to the other speaker, allowing you to run these speakers as monitors or subs. The bridge option runs both speakers on the same channel, making it a mono signal, so if they are used as monitors, everyone hears the same thing. If they are used as subs, equal power goes to each, reducing the chance of a blown speaker.


Hope that helps!

you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.

PXA-H700 optimum set up...


The way the EQ is hooked up is correct.

You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.

I believe your problem lies in the amplification.
Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
Low powered - high in sound quality.

You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
Now the amplifier is working harder to produce the same output.

You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.

a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
and bridge channels 3 and 4 for your subwoofer.

For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.

a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D

If you need more help - just let me know.

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.
A thumbs up would be greatly appreciated if this answer is helpful to you. best-way-connect-4-speakers-sub-4-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

How too hook my kac 7201 up to my two dual 4 ohm Alpine type Rs


Hello manbearpig65,

Well, that's a 2-channel amp, so it's really best used to power a set of regular speakers.

The best power solution, for your existing components, is to wire each of your subs voice coils in parallel, resulting in a 2 ohm load, and then run each sub off a separate channel from the amp.

The amp is stable only to 4 ohms in bridged mode, so you would series the sub voice coils (8 ohm load) and then parallel them (4 ohm load) to the amp bridged connection. This will result in less power to each sub than if you ran them separately.

Hope this helps.

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.

Why connect a car amp in series and will this help me?


Not sure if it's what was meant by previous poster. But if you're just driving the two subs off the 4 ch, and no other speakers, your best bet is to run pairs of bridged channels, ie use the 4 ch as a more powerful 2 ch amp. Then independently run one sub on each of these paired channels.

If you bridge all 4 channels (not sure if this is an option on this amp), and then run your subs in series, you will likely lose out compared to the peak power you could be seeing with two independently paired channels.

Amps


It comes down to Amperage and RMS, your best bet is to go in and talk to a salesman at a stereo shop. That way he can decide on what sort of power you want and how you wanna use the subs. But 1000amp AMP is probably a good start 4 channel of course. Alpine or SOny make some kick a$$ AMPS

How to wire a stereo system


Connect the 2 gage to the battery thru at least s 50 amp fuse, then connect the capacitor in line before the amps. Then run the 2 gage to a connector/splitter block and run 4 gage leads to each amp. You also will need at least 4 gage ground leads from each amp to a body grounded bolt or screw. You need to run a quality set of speaker leads from the head unit to the amps. The speakers will need separate leads from the amp to each speaker.You will need to try some different combinations to get the sound and bass you want. You want to be able to fade from front to rear and control everything thru the head unit.
Use a hole saw to cut a 2 to 3 inch diameter hole in the side of the speaker box for a port to get a better punch from the sub.
Hope this helps some....
