Amps & ICE q's

Hi all, wanting to get my hands on an amp but don't know much about these things. Can someone clear up their function for me, what I need to look for etc. I am running Pioneer through all my speakers and head unit is also Pioneer so want to keep the same theme running through. What does it mean 4 channel, bridgeable etc? Thanks

4 Channel = how many speakers it can power.

Bridgeable = can bridge the AMP with another so you can power more beefy equipment.

I think those are meant to be a good wee unit for powering speakers.

Thanks guys So boon- if I am going to get a sub in the future should I look at a higher rated amp? What would a 10in sub need? 1200W amp? Sorry, should probably google this **** lol

I would personally run a nice 4x50wrms amp for the door speaker and buy a seperate mono block amp for the subwoofer. These are usually a D-Class amp which are great for subs. D-Class amps are very power efficient and handle transients really well. It also becomes less necessary to run a capacitor in the circuit etc etc. I could go on for hours, anyway, these mono block amps are also a single channel (hence mono)and giving th sub its own special amp will improve performance and sound overall.

What the sub needs, is basically dependant on the subs power handling. Find that out, then you'll know.

And go by the RMS value, not the MAX value.

Sweet, I get it! Thanks guys

I currently run a 50RMS x 4 channel Rockford fosgate amp which came underrated from factory and was actually had an output of 60 RMS per channel as per the certificate that came with it.

I run Polk Audio DB6501 (rated at 100RMS) component speakers on 2 channels and run an infinity sub on the other 2 channels bridged. I had to turn the bass down on the sub down because the bass was hitting way too hard for my taste.

Try and get reputed brands because I have run cheap amps which claim to have higher RMS ratings than my Rockford Fosgate amp but don't even come close.

Any pics of the speaker install? Keen to see how you hid the crossovers. Assuming you have a V8 STi.

Yeap I have got a V8 STI. I don't have any pictures of my current setup on my phone but will take some tomorrow for you.

The Polk speakers were quite easy to install as the car came with some Alpines before and already had a custom spacer built that I re-used. I did not want to use the stock tweeter mount because the tweeters came with the appropriate brackets etc to mount on the sail pod and it looks much nicer on the sail pod. Also, I like the tweeter height and placement on the sail pod due to the difference in sound too but everyone has their own preference so try both locations.

The crossovers were mounted inside the door near the bottom so that window glass would not hit. It was a bit tricky to get it right but in the end it was worth it as there is no rattle from inside the door due to the thick tape I put under the crossover before mounting it.

Luckily I have pics of my old bug impreza which I used to own 3 years ago with a similar setup except in this the crossovers are placed outside the door as seen by the images. The tweeter placement is exactly the same as my V8 STI.
