many thanks for all the good suggestions to my recent post. I don't want to sound thick but can anyone in the younger generation help me out. I get the idea of using an FM modulator to connect my i-Pod. and I have already replaced the speakers, Kickers in the front and Radiomobiles in the back. I have also decided to keep the original radio cassette. But one suggestion was to fit a further amp on the radio output. I've looked at these on the internet and must admit to be bamboozled by talk of RCAs, cross-overs etc. Can anyone explain to me in simple English what I need to look for when buying such an Amp?

An RCA is just a type of plug or connector that you would find on the back of a stereo, DVD player or TV (see pic)

A crossover is an electronic filter for audio systems that splits any frequencies that a particular speaker is incapable of playing by filtering the undesirable ones out.

 

It's probably best you go into a god ICE shop and ask for advise about what you want to achieve

This can get very expensive!! What I did didn't cost a lot but it works very well.. Dont get too hung up on wattage figures, as long as the total speaker wattage is higher than the amp output. I'm running 2800 watts worth of speakers from a 400watt amp, and it will blow your head off! It's all about the ohm rating.

Buy a decent power amp (not a chinese cheapy from ebay) I got a JBL 2 channel stereo amp and stuck it in the glovebox.

Wire an ignition live from a switch and wire the speakers in parallel. Most amps run at 4 ohms a side, so make sure both speakers are 8ohms then wire like this,

The ones in the diagram are 4 ohms resulting in 2 ohms. Only expensive amps will run at 2 ohms.

If you have 2, 4 ohm speakers you can wire in series which will flip the ohms the other way and not over load your amp

Never overload the amp, it will not last long. The lower the ohm calculation the more draw there will be.

 

Full range speakers dont need crossovers, only needed when running tweeters and bass bins.. leave that to the saxo drivers..!

 

I just wired a 3.5mm jack to the amp so I can listen to my ipod, not a big fan of the radio but I can plug my phone in and listen to the radio that way. You can use the speaker out from your original radio (unless you have a modern radio with an unpowered signal out aux, then it will be ok) and wire to the amp, but the amps that can handle a powered signal input are expensive.

Have you ever used one of those fm transmitters before? they're shit.

Nothing beats a hard wired system...

I wanted to leave the orginal radio as is and run the new set up separately. My orginal radio only had one speaker on the dash top anyways.

Make sure all speakers are wired properly, if not they will run out of phase resulting in the bottom end cancelling out....

Good luck!
