jlaw Posted November 24, 2008 Report Share Posted November 24, 2008 What's up, I currently own a 12" Kenwood sub, wired at 4 ohms 300 watts. I want more power, so I'm looking at two 12" MB Quart RWE-302. The specs are here== http://www.woofersetc.com/index.cfm?fuseac...Product_ID=3415 , I want to buy 2 of these so I can run 1000W RMS, and I want 2 12" subs. I want to power each sub 500watts rms, but I need help matching an amp for each sub, I have this amplifier== http://www.woofersetc.com/index.cfm?fuseac...Product_ID=6401. I was wondering if I wire my Kenwood amplifier to the MB Quart at 2 ohms if it will run at 500, and if so I want to buy another amplifier like this one and run both MB Quarts off of 2 Kenwood amplifiers at 500watts RMS per sub. I also need help cuz I want to buy a dual 12" ported box, and I also need to know the Gauge wire , and if I need a capacitor. I'm brand new to the whole sub scene so if you could help me out it'd be much appreciated, thanks a lot! i also tried hooking up a kenwood head unit to my 2001 GMC Jimmy, with a Bose system, I put the harness on and wired it all together, but there was no sound.. The head unit worked but no sound came out of the speakers, if you could help me out there, I'd be even more grateful, hit me back please!!

donsie Posted November 24, 2008 Report Share Posted November 24, 2008 The sub page won't load for me, but I got the amp page up. Yes, your amp with run at 500 watts RMS if you wire it down to 2 ohms. If you get two, you will need to buy a distributor to split the power wires into 2. For this setup I'd say get a distribution block that has 1 1/0AWG input with 2 4AWG outputs. Run a small amount of 1/0 from the positive terminal on the battery into the block, and then run the 4 out of the block to each of the amps.

amazinblazin10 Posted November 24, 2008 Report Share Posted November 24, 2008 yeah dude just do the big III upgrade and like donise said you'd need to get a distribution block but those are relatively inexpensive. as to your dual ported box, why buy? learn to build, you'd get so much more satisfaction out of building one, and you can build it specifically for that subwoofer, but hey if you aren't able to build one at the moment that's totally fine, as to you head unit problem.. can't help ya there sorry.

donsie Posted November 24, 2008 Report Share Posted November 24, 2008 (edited) Just got the sub page working (shitty college wireless network)...Unfortunately the amps won't be able to see a 2 ohm load using those subs. The subs are dual 2 ohm voice coils. If you plan on wiring each sub up to their own amp, you could wire it in parallel which would bring the load down to 1 ohm on the amp, but your amp isn't 1 ohm stable. You'd have to wire the voice coils in series to the amp, bringing the impedance up to 4 ohms. This means your subs would only see 300 watts rms a piece. If you can find the sub with dual 4 ohm voice coils, then you can wire them in parallel and the amp would be seeing 2 ohms, resulting in your subs seeing the 500 RMS you want them to. As for the rest of the questions not answered before, can't help with the factory amp. I doubt you'll need a cap or anything, just do the good ol Big III upgrade and you should be good. Add another battery or a cap if you get a lot of dimming when the bass hits. EDIT: Don't forget to get a fused distribution block for the power wires or you could fry some sh!t Edited November 24, 2008 by donsie Quote chicken is basically the native american hulk, you think he broke that curb with his rim? think again, that was merely him stubbing his toe.

jonathancullen89 Posted November 24, 2008 Report Share Posted November 24, 2008 does the bose system use an external amplifier? maybe u need to hook up rca's to something. if all else fails run new speaker wires to all the speakers Quote 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!- Link to comment Share on other sites More sharing options...

Beanz Posted November 25, 2008 Report Share Posted November 25, 2008 but if you run thoe subs with those amps after you wire them they will be seeing a one ohm load which your amp cant handle.And for the head unit is the harness ment for that one.Cauase i know that their is seperate harness 's one for the reagular stereo and one cause the bose's have a amp so it'd be a speciality one. Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

Get the 4 ohm model. That was you can wire it down to a 2 ohm load. Your amp won't see a 2 ohm load with dual 2 ohm subs.
