Christmas has brought a new CD player and money to spend upon the Fiero, so I have decided to put a subwoofer better than the stock one in. I have read "Looks stock, sounds great" and "One man's quest for more bass" and have settled on the sub from "Looks stock". (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-831) However, the amp he used, and Xtant1.1, seems to be nonexistant. So, I have done a bit of searching and was wondering if someone could tell me if the amps I am looking at would work. If they wouldn't, would somone be so kind as to show one that is?

Thanks in advance!

I wouldnt recommend any of these amps if you want your bass to have a good tone to it. These are entry level amps at best and you are better off to steer clear of them!!!

This is a referb but much better quality.

This years model of the same amp, new in box.

There are other quality amps out there but the kicker amps seem to be some of the best when it comes to the features vs power vs price, IMHO.

Thank you for keeping me away from the cheap stuff, but my main issue is that the sub I was looking at is 40 watts RMS and 80 peak. I suppose as long as you kept the amp turned down it would be fine, but it seems to be a waste of wattage. Maybe somone out there has found a higher power 5 1/4 inch sub?

Edit-
Maybe something such as these?

I dont know anything about the sub in your first link but you usually want to steer clear of the Pyle gear. Several years ago they made decent mid level products but the gear went right down the tubes about 8-10 years ago.

I also didnt check the specs out on the original speaker you wanted to use. I was simply using the spec's from the amps you had posted in the links.

Here is a Memphis amp that would work the sub over quite well.

Heres another Kicker. It is rated at 100 watts. 10 Watts over the peak power of your sub.
http://www.overstock.com/El...2667466/product.html

In most cases you can power a speaker with more power than they are rated for provided you have good clean power supplied to the speaker.
I wouldnt be affraid to run the sub on either of the above amps. If you are concerned about exceeding the specs on the sub the memphis is 10 watts under the max power rating.

There are more options out there than the above amps. These are simply a couple that I ran across in a quick search. A couple things I would recommend you look for when you purchase a amp:

1) Make sure the amp has a built in low pass crossover. This will keep the vocals out of the sub and allow it to play at a louder volume since you wont had as much distortion due to it trying to reproduce the higher frequencies.

2) Try to buy a quality amp. A general rule is roughly 1-3 watts/dollar, For some reason the lower output amps actually cost more $/watt than the bigger amps. A few years ago a amp in the sub 100 watt range would have been easy to find and would have ran you roughly $100-150. However todays bigger is better phlosophy <sp??? means a lower powered amp is not in a high demand causing them to cost more than the higher output amps.

Last but not least. Years ago several companies made 6 and 6.5 inch woofers. A quick search for a 5.25 inch woofer turned up almost no results. I found a few speakers but they were from companies that I would not recommend to you. If you find some more speakers link them up and I will be happy to give you my thoughts about them.

remember rms isnt how much is required to power it but how much power it can handle constantly for a given period of time. thusly peak power is how much it can handle for a short duration of time. things like volume, gain and bass boost alter how much power the sub will draw not how much you send to the sub so yes if you keep the settings down you should be fine. as for an amp, due to the limited space in a fiero you pretty much ahve to put em behind the seats which will make an amp nice and toasty so look for a digital amp (class D amp). they dont get as hot unless you crank them up.
