New sub, now I need an amp
I have bought an Infinity Reference 1230w, but I only have 25W RMS going to it and it needs 300W RMS. Its peak power is 1200W so I wouldn't like to go over a 900W peak power amp. I have looked and there are many different kinds of amps at many different prices. I need a 2 channel I can bridge or a 1 channel at 4 ohms. Oh yea, my price range is about maximum $200, this isn't very high but I am on a budget of $80 a week. Any help would be appreciated, thanks.

How do you measure how many cubic feet the box is? My box is about 12.75Wx12.75x13.0H. I need a 1.25 cubic foot box, and was wondering how big of a difference the size of the box would make? I am new to car audio.

your box is about .85 assuming its made of 3/4" wood. do you happen to know the minimum recommended box size is for that sub? you can put about 1 lb of polyfill into the box to make the sub think its in a bigger box. id just do that and put 200-300 watts rms to it.

The recomended internal box volume is 1.25 cubic feet, I am tryin to calculate what the dimensions would be for a 1.25 cubic foot box but I have yet to figure it out. I would like to make my own box, the wood would be 3/4". The box I have now is made out of 1/2" wood. Would I find polyfill at Lowe's or Home Depot? Thanks.

this should help.
yeah build a box out of 3/4 mdf. you can find polyfill at walmart for like $2.
edit: go to #110 on that website.

Until then I will stick with the 25 watts I have going to it now
oh BTW, how are Legacy amps? how would this amp be in putting 300 watts continous? http://cgi.ebay.com/ws/eBayISAPI.dll...703438936&rd=1

Yea 25 watts, at leasts that what I believe thats what it says on the back, but I could be wrong about the 25 though, but I know its not more than 100. I'm not sure what bump means but it hits hard and makes plenty of bass, enough to make things in my car shake at least, thats with the gain turned up 3/4 the way.
I am not sure about Legacy but wth the shipping included on that item it would be about $55 and I found the same thing for $46 withought shipping and it's probably about $60 shipped if you don't like buying from ebay, LA220. What I was reading is that it is 300 watts peak powerI believe, but I could be wrong, Specs.

Thanks, Mooney
Edit: I have a Rockford Fosgate Punch 100a2 powering it.

looks like its getting 50 watts assuming is a SVC sub. its probably being clipped which means you are sending more power than the amp normally produce so it sends "dirty" power and causes clipping which can cause popping in your subs. if you like how it sounds maybe just build a big box and see if you like it with the current amp.

Shoot it's late, anyways. Will the popping caused from clipping mess up the sub? Also what is an SVC sub? Thanks for all the info, if these questions are answered this will be all the imformation I will need. Thanks again.

popping will definately damage the sub. It is called distortion and will blow your sub. SVC is for Single Voice Coil. DVC is dual voice coils. The difference is mostly in wiring configurations for the sub to get the most power out of an amp. A DVC will not get any more performance than a SVC with the same power going to the sub.

It is a SVC, I don't hear any popping or distortion. If I turn the gain down on the amp will that help make it not pop? I just want to make sure I don't blow it.

its hard to hear clipping inside the car so go and do this... put on a bass heavy track and put it up to the highest volume you will ever play it at. then go open your trunk and listen to the sub.. if you hear anything strange then lower the gain. do this for about a minute to see if you hear any clipping, but dont **** of your neighbors.

I will try to listen to it in the trunk, I have already **** my neighbors of enough so I don't believe one more time will hurt. I got a new amp today from a friend, it is a lighting audio 450W max, 150.2 RMS. I bridged it so will it make more than 150W RMS? The recomended lowest RMS for the sub is 100 so I think I will be okay, and i have the gain turned up a little over 1/2. Thanks, for the info.
