My friend says it's not wise to do, but it seems like a couple people have done it

 

I have a mono amp going to 3 subs

 

Monoblock amps are specifically built to run subwoofers. Multiple subwoofers are generally no problem with them. I have 2 on my monoblock JBL BP1200.1. Your friend doesn't know what he is talking of. In most SPL cars, only mono amps are used on the subwoofers. Typically multi channel amps are geared towards mids/highs because of the stereo sound and higher range on the freq scale, and they are ususally less effecient than the class D switching found in most mono amps.

 

Should be no problem at all as long as it is hooked up properly (ie total impedance the amp sees is correct). With this in mind it is possibly even better to hook up two like subs to the same amp. Both subs will be assured the same amount of power and perhaps more accuracy with both subs getting identical signals.

From this I take it your friend is not as wise as he/she believes. I have always felt that it takes time or experience in a subject to gather wisdom. It only takes one days experience installing car stereo's to determine the value of a mono amp for powering multiple subs.

 

do class d amps take more power from the battery than a class a or b amp?

 

In general class D's are more efficient (ie less battery drain) than same size class A or B's. The trade off is sound quality. That is what makes them ideal for subs. A lot of power, little battery drain, small size, and a little lower sq.

 

Your friend is a dumbass and is trying to sound kewl...Start by raising your leg to the rear then in a swinging motion kick them in the nuts and tell them to stop talking like the know anything.

 

so i hooked up a 600.1 with 4 gauge wire to my 02 max, with stock battery, will my headlights dim? because i dont want my xenons dimming, imsure its bad for them, and it looks ghetto.

 

thank you guys ... i didn't think he knew what he was talking about, but i just wanted to make sure before i purchased the amp .. i'm gonna be going with a jbl bp600.1 amp running to 2 pioneer 304dvc (impp) subs .. max is 600 watts, and nominal is 300 watts each .. thanks for your help

 

why the DVC's? Just get the 4 ohm SVC version.. and wire in parallel..

 

Yeah, good point. I missed that. Although the JBL may be stable at 1 ohm, it will run hotter. And probably draw more current.

 

You could also run a 2 channel bridged mono for a single load to multiple subs. That's how mine are set up, 1.5ohm final. Although as of this morning the amp has given up, not sure why yet.

 

ok guys ... i finally made a decision ... i went with the rockford fosgate 700S on ebay ... http://cgi.ebay.com/ws/eBayISAPI.dll...393471625&rd=1

 

I have a MTX amp powering 2 subs. Works fine.

 

My mono block amp is 2 ohm stable and running 2 12" 4 ohm subs and works perfectly.

 

JBL puts out an underrated 600 watts RMS, so that is far more than 600 max...

 

"Monoblock" doesn't neccesarily mean "mono sub amp".. there are plenty of full range monoblocks, and are considered by some to provide the best sound quality up front..

Zapco & Sinfoni come to mind.. ie- http://www.ampmanaudio.com/products/details.asp?id=999

 

yes, but he has two subs.. 600w RMS / 2 subs = 300w RMS per sub..

 

I thought when he said
He meant the bp600.1 put out 600 peak watts...

 

I guess that's the connection I made..

Conrad?

 

i decided not to go with the jbl ... instead i got the rockford fosgate 700S ... it'll put out 350 to each sub, and it's 2 channels

 

Good luck with it.. be sure to get an insulated female spade for the remote turn on.. the clearance is not always good, and they tend to short to the amp chassis..

 

good choice with the amp, better to have extra power laying around =]
i dont think i know anyone running an amp for each of their subs, im running a JL 500.1 to 3 10" Cerwin Vegas, not a problem here,

sorry, but ur friend is a moron

 

i knew he wasn't right as soon as he told me, thats why i posted it here .. thanks for you help ...

now when you say i need some power does that mean 1) yellow top battery or 2) 1 farad cap

 

When the engine is on, you need the cap. When the engine is off, you need the battery.

 

so i would need both
farad cap on ebay is this a good one?

 

only 2 things to know about caps,

1. low ESR rating
2. 16v rating
