    hey i was wondering if i can get some help in picking out an amp. im getting a infinity perfect 10.1d. im thinking of getting the Sony XM-DS1300P5 amp but i thought id get your opinoin on it first. i was reading how the frequency on the sub goes down to 18 hertz and the amp plays down to only 40. is there a noticeable difference in that. any suggestions would be greatly appreciated im looking to spend no more then 200 on the amp. other info: the amps going in a sealed box, i listen to mostly rock and metal if it helps. and one final question do you think the sub would sound better in the trunk or behind a front seat in a coupe? thanks!

    get either a memphis 500d or 1000d depending on what voice coil configuration the sub is

    The amplifier may be only rated to go to 40hz (not sure why that is) but most likely its real limits are somewhere in the 10hz or lower range. Perhaps you were reading the lowest crossover setting by accident instead?

    And the response of your subwoofer will depend on several variables. It could end up going below 18hz in a car.

    As for the sound, you will just have to play around with it to see which location you like better.

    hey thanks for all the help so far, i was reading on car domain that they recommend the jbl gto300.1, what do u think of that one and where can i find it online for a decent price, not a lot of people carry jbl amps. also im still a little questionable of the overall quality(SQ, performance, etc...) of the Sony XM-DS1300P5 amp. thanks again

    i was totally gona suggest that too :) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=18797&item=5707078666&rd=1 I used to have a bp1200.1 and it put out a ton of power and was worth every penny. As long as the quality hasent changed to the new models u have nothing to worry about. And u wont notice a difference in sound quality between a JBL and an MTX amp or something...

    the sub is underrated as well, I hear the optimum for the sub is 700-800 watts

    700-800 watts?? are u sure about that, from what i know the infinity subs are very fragile and shouldnt be sent more than the rms power rating.

    can any one back either of these up with either knowledge or experience?

    You can put as large or small amplifier on the subwoofer as you want. It can work fine (although your max output can be limited) in any of these situations as long as you are smart with the volume control. You could even put an amplifier rated 4 times as much as the maximum rating on the woofer with no problems, provided you dont crank it up too loud for too long.

    IMO matching the power rating of the woofer with the amplifier is not necessary. Its often a useful rough estimate, but dont think that you have to match the numbers up for 'optimal' performance.
