Is the Maxi-Cosi Pebble (UK Spec) comparable with the 2007 Honda Element (US Spec)?

I don't really know about the Honda element but I do know the maxi cosi is one of the most popular, reliable, trusted, affordable and safest car seats on the market.

No sound thru horn.

Either components in the SoundGard circuit are blown or the horn driver... VERY SLIGHT chance wires have become disconnected. Open unit an inspect. Use ohmmeter to check the polyfuse and the lamp for open circuit indicating they are blown. Your amplifier should be rated at NO MORE than 150 Watts RMS continuous for safety of the horn. Speaker ratings are based on advertising... so don't believe the specs on power handling... If you dig into the specs you will find for the horn a max of 150 Watts continuous.

I think I need to replace the tweeter in my EVID 3.2. How the heck do I remove the grill without damaging the unit?

The grill is glued on and will pop off with a little effort. Use a small pick tool (small pointy tool with a sharp hook) and carefully pry the screen away from the speaker. Try lightly prying in several spots so you don't warp or bend the screen. Let my know if you find replacement parts

Where can i buy a horn for a ev sx 300? how much?

You don't "buy a horn" as the horn itself is molded into the case and if the case is smashed that is fatal.

If it is the sctive element for the tweeter/mid you are after, the correct terminology is "compression driver". That should aid your search.

It is best to go directely to EV to get an exact replacement for this. Or try to find one at this site:

They vary from about $30 to $500.

I have an old set of EV 1502 PA Speakers. One of my Cabs the 15" driver stopped working... I can plug the Horn and the 15" Driver in Separately and they both work which I think means I have a problem with...

The crossover network is a combination of a LCR circuit. since all these arre passive components you will not have a problem to find the actual fault. Since you have confirmed with the drivers, the line in to the network from the speaker wires must be traced for continutiy, use a good multimeter. now check carefully on the PCB-printed circuit board.- for any track damage on it, if so loop and connect. The main driver is usually in parallel to the main line but with a croos over of a cpacitor and a series inductor. This will be the culprit, either it has come off from the PCB or open out by burning off. replace or reconnect. I am sure it can be sorted out easily by your carefully analysis. Hope this helps. Good day

Start looking for a replacement, you won't get it fixed. Try the makers website, they should put you in touch with someone or supply the part.

I have an Electrovoice MA-1212 That when I hook it up and power on all I get is a constant low frequency Hum. Checked the wiring and speakers on another amp and eliminated them? Any suggestions?

WIth the speakers disconnected, measure the terminals using a DC voltmeter. I suspect that there is DC voltage there where there should be 0V. If that is the case, the output transistors are shorted and need to be replaced.

Wiring tweeters.

Yes you need them. I always put them inline on the positive side. They are to protect the speakers against low frequencies. Actually, I use oil bath capacitors sometimes on pro systems. I don't see how they would work between the positive & negative that is unless they have a positive & negative side with an out and an in? Hope this helps,
