Hope someone can help as i know just about nothing about ICE.

Want to run some components up front, some 6.5inch 2 ways at the rear and a small 8 inch sub in the boot.

The head unit is an Alpine CDA-9812RR

Right so I was going to use the head unit to run the rear 2 way speakers.

A Polk MOMO C300 amp to run the front components:

Power
Channels 2/1 (bridgeable)
Total Dynamic Power (all ch. driven) 850 watts
14.4 Volts RMS Not Bridged @ 1kHz
4 Ohms 150 watts x 2
2 Ohms 220 watts x 2
14.4 Volts RMS Bridged
4 Ohms 450 watts x 1

--------------------------------------------------------------------------------

Electrical
Signal-to-noise (Referenced to rated power) > 105 dBA
Remote Gain 0 to -30dB
Input Impedance > 10k Ohms
Output Impedance < 0.02 Ohms
Overall Frequency Response (-3 dB Points) 10Hz - 45kHz
Protection circuitry Power and ground reversal, Thermal and Short, Current Overdraw and Low Impedance Protection with auto stand-by mode

--------------------------------------------------------------------------------

Dimensions
Overall Dimensions (with panels) 2-1/2" H x 13" W x 9-3/4" D
(6.35cm H x 33.02cm W x 24.77cm D)
Product Weight 12.00 lbs.
Total Shipping Weight 13.50 lbs.

--------------------------------------------------------------------------------

Filter Settings
Subsonic Filter 24dB/oct @15Hz
High Pass Filter frequency 50Hz - 250Hz
High Pass Filter slope 18dB/octave
Low Pass Filter frequency 50Hz - 250Hz
Low Pass Filter slope 18dB/octave

Is that all I need????

I was going to uprate the std Mitsi battery to something a little more powerfull.

Any help would be much appreciated before I go and buy this little lot!

I have asked similar questions before but this time it is defo getting bought so thought I would make sure i have it all right.

Thanks

What sort of price do audio centres charge per hour Manjit, sure it differs greatly but ball park?? And how long to fit system like the one I'm going for. Bit worried the money is running out, but its too late now! :crackup:

for what your looking at i'd say £100 is cheap, £200 is reasonable - but i can give you some pointers re what to look for! and £300 is expensive.

for £100 id say it would be an almost chuck in job.

£200 - all the cables should be tied into the origional harness on the runners, power cable should be grommited front and rear, power cable should be correctly fused. Tweeters should be mounted correctly according to IASCA ruling. All gains setup without clip.

£300 - same as above but fancier!!

Wow speakers turned up today look awesome mega quality:)

Having bit of trouble finding the C500 monoblock amp to run the sub at the moment though. Could I run the sub using the 2/1 channel C300 amp :confused: God its embarrasing that I dont have a clue about this stuff need to do some reading :eek: That way I could buy another C300 amp which i can find or even better perhaps the 4/3/2 channel C400 which looks the bizz?????

the c400.4 would give you better performance compared to the c500 and the c300 - its not all about power-you have to take the efficency of the electrical systme into account.

The choice is: standered battery: c400

Uprated battery front and split charge rear : c500 and c300

The c500 will draw around 70amps @ 2 ohm bridged and the c300 will draw approx 83apms ...

The C400 driven at 2 x 75w fronts and 1 x 200w rear will draw 68 amps ... more efficient - AND taking into account that you only have a 90amp altenator I'd say this was the better route to take.

Awesome cheers m8 since I havent paid for the C300 yet I will see if I can change it. :) I didnt think the C400 would be powerful enough to run the components and the sub, but if it can then that is brilliant!!!! :jump I bought a 10" sub by the way on your recomendation :cool:

Thanks you, you are saving my life and Bex wallet :D
