Amp to match 15" Fusion Sub

Lenny New member Username: Triangle Post Number: 1 Registered: May-05	Posted on Saturday, May 21, 2005 - 04:44 GMT I have a http://www.fusioncaraudio.com/products.php?action=view&product_id=34 If you click the tech info, more stats are available on the pdf. The shop remommended an Alpine MRD-501 AccuClass-D Mono Power Amplifier for AU$700. The brochure says: 550W x 1 RMS [2Ohm @ 14.4V (1%THD)] 275W x 1 RMS [4Ohm @ 14.4V (1%THD)] 425W x 1 RMS [2Ohm @ 12V (1%THD)] 225W x 1 RMS [2Ohm @ 12V (1%THD)] 8.5V Input Capacity blah blah blah I havn't used Ohm's law since I was in high school and I can't figure out how to match the figures for the amp to the figures for the sub but the recommended one seems too small to me? I believe the sub is fairly up there in the quality range and I don't want to hurt it by using an underpowered amp. With the Sub being 800W RMS and 1600W Max with dual 4 Ohm each voice coils, what Watt and Ohm combination mono amp should I be looking to get? I intend to bolt the Amp to the side of the sub box and sit it (securely) in the back of my '05 blue suzuki jimny when I don't have need for the back seats... with any luck, it will vibrate the mud off so I don't have to wash it... Cheers, Triangle

Not even close to enough power. As for wiring the subs, do it like this. You will have a end ohm load of 2 ohms. Get a mono amp that will do at least 800w RMS @ 2-ohms, if not more. It's better to be over the RMS of a sub then under it. Hope that helps.

If I stick with the brand of the sub, I think the amp I need is slightly bigger than the http://www.fusioncaraudio.com/products.php?action=view&product_id=98 but not as big as the http://www.fusioncaraudio.com/products.php?action=view&product_id=99 Just running this past you to make sure I'm on the right track... Thanks for lending your experience!
Lenny New member Username: Triangle Post Number: 3 Registered: May-05	Posted on Saturday, May 21, 2005 - 06:01 GMT I found a list of feasible amps @ http://www.cardomain.com/shoptype/Subwoofer+Mono+Amps and came up with these candidates all with 800W RMS @ 2 Ohm http://www.cardomain.com/item/ABNA8000T Audiobahn A8000T http://www.cardomain.com/item/BOSRT1500D Boss Riot 1500D http://www.cardomain.com/item/MTXTA7801 MTX Audio Thunder TA7801 http://www.cardomain.com/item/MTX801D MTX Audio Thunder801D http://www.cardomain.com/item/POWA1000DB Power Acoustik A1000DB as well as an this 850W RMS @ 2Ohm that I figured was close enough... http://www.cardomain.com/item/KENKAC9102D Kenwood KAC-9102D I have read that high quality brands sometimes give lower ratings for their amps so that they can get into lower categories in competitions so I'll also add these 750W for opinions sake http://www.cardomain.com/item/ROCT10001BD Rockford Fosgate Power T10001bd and 760W http://www.fusioncaraudio.com/products.php?action=view&product_id=98 FJL-811D If any of you can sort this list from most awsome to least awsome from a quality perspective, then I can hit the local shops and see what I can afford. Any comments on weather any of these amps might clip with the max power of the sub being 1600W would also be appreciated.
