Need some help picking an adequate amp Options

[computers4kids]

Recently changed my pod speakers to the ones below and primarily just use my phone or ipod. Pretty much never listen to the radio. No amp.

I've come to the point I would like some more volume and quality sound and would like to add an amp and a sub--need your help. I don't want to cut my doors for more speakers. Hopefully a foot sub or console sub with these speakers will be adequate for me. I'm thinking of mounting a amp in my center arm rest with a little modification or behind the driver seat. I don't want to mount the amp in the trunks.

Can you help me know what size amp (RMS) I need as a minimum, number of channels, and do I need a premamp. The guy at the stereo store said I need a premamp if I want really good sound without static?? Speak slowly...I am not a stereo guy LOL (IMG:style_emoticons/default/smile.gif)

A good 4 channel amp. ~100 watts per channel. Two front channels to your plate speakers, the rear will be bridged (both channels in to one) to run a 8" or so sub. Don't think you need a pre amp personally with iPod. You can adjust the input signal on most amps to tweak the sound. You will need to get an adapter to get al 4 RCA connections to one 3.5 mm iPod plug. Make sure the amp has a built in crossover, you don't want to put any bass in to your plates and you don't want highs in your sub.

Bottom line...

Buy a name brand amp. (Kenwood, Alpine, Rockford Fosgate, etc)

100-200 watts

The fedral trade commission does not regulate car amp ratings. So, the manufacturers can claim any output they want. Major manufacturers (name brands) will rate their amps correctly. Off brands will claim outrageous ratings.

This one should drive everything fine, wont be one of those b boxes, but will be loud and clear.

Thanks. When you bridge to channels together do you get the RMS watts of both channels added together or less?

My last car I had used y connectors to connect a 2 channel amp. Is a kit like the one below worth the effort to gain an external volume control separate than the ipod? Currently I have a cable that charges my ipod as well as sends the signal to my period correct radio.

Bridging will "double" the output. Not truely double but close. You can also run in tri mode; 2 stereo channels and a bridged mono channel for bass.

Might be a nice option, less adapters and your iPod will never go dead. Not sure the volume control would be handy or not. How much is that kit?

$59 Since the ipod/phone sits between the seats the volume control might be handy for not having to look at the ipod while driving. Another option would be to use the volume control for just the woofer since I'm not sure how easily the controls on the amp are going to be.

Cheap enough. You can always adjust the bass through the eq function of the iPod as well.

What do you think about one of these for some base in a 914?

Boss Audio BASS900 - 8" Low Profile Amplified Subwoofer, Remote Subwoofer Level Conrol, 900W

May be OK however, this proves my point too. Look at the fuses. Two each 15 amps (30 amps total)
Power=Amperage X Volts
14V X 30A =420 Watts max

So they claim 900 Watts but ohms law equals 420 Watts. Boss is not a name brand. But this setup may work fine in a 914.

Actually, I was thinking of something like this in addittion to an amp. I liked the compact size and could be tucked away and be self contained.

I ended-up buying the amp below but now trying to decide how to do the base. I have coca mats so I believe the floor sub idea is out. Don't want a center console. Still thinking.

Those are the details that are good. (IMG:style_emoticons/default/smile.gif)

That way you don't have to try and compensate bass with the ipod EQ at 80hz when the frequencies you 'feel' are more-so 30-50hz.

EDIT:

Can you provide a link for the volume control connection kit? I've considered just running an amp with input jacks, but having a volume control other than what's on the iPod would be nice.

The kit to connect an ipod/mp3 player to a 4 channel amp can be found at here.
Price is $59

If you go to buy this amp...do an internet search. I found the price varied over $130 (159-270) from the usual suspects, some even included no tax and free shipping. Interesting enough, Walmart was one of the highest.

Mark...I have pretty much that same amp in my truck (few years older model) and have been happy with it ever since. I have it running 2 5 1/4" components and a 6" component set and it works fine. Should work great for you.
