can one amp run all my speakers?

by **navarachi** » Sun Jun 18, 2006 12:28 pm

i have 2 alpine type e's and two type r components. my rears are stock b/c they really don't matter much and im happy with them. Was thinking about buying one big ass amp, probably a power acoustik. Can i do this or should i keep the hi/low pass seperate w/ seperate amps?

Thanks,

Chris

just find a powerful 4 channel amp. use the front two for your comps, and bridge the rear two for your subs. might be eaiser to find the power in two seperate amps though...

Ther are 5 and 6 channel amps out there that you can get for example the Jl audio 500/5 wich will run the whole system.

donkey = as.s. Congratulations, you have just discovered that for some unknown reason, the mods censor adult language, although there's no 8 year-old kids driving or joining this forum any time soon, which is frustrating considering it takes away your intended tone (e.g. you're calling someone a mofo and it comes out jerk, so "I came home to that jerk eating my girl out" sounds like something almost in praise), and the fact the replacement word is uber long.

You can definitely get 1 amp to power your complete setup... And you have a few ways of accomplishing this:

#1 get a 5 channel amp
#2 get a decent 4 channel amp and run your 4 main speakers off the front two channels in 2 Ohm Stereo, then run your subs off the rear channels
#3 get a decent 4 channel amp and power your front two speakers off the front channels and your subs off the rear (powering your rear channels straight off the headunit)

Yeah, the curse filter really takes the impact and substance out of the ideas you try to get across sometimes.

is there any difference in running 2 amps then just running one for the whole system? Because i have 2 10" JL audio's that i want to put for bass so do you think i should get a 2 channel amp for those and a 4 for the 2 speakers in front and the 2 behind the back seat? And Also do tweaters need there own channel ? Ohh and how many watts would you recommend for the 2 10"s and how many for the regular speakers.

Is there any difference in running 2 amps intead of running 1 for the whole system? Yes and no... An amp is an amp, the main purpose being to amplify power driven to the speakers from the headunit. Either way you go (1 or 2 amps) they will accomplish this. Many 5 channel amps put out are actually 2 amps in 1 chassis (JL and Alpine are both known for doing this). If you can get 1 amp (in one of the setups I mentioned above) to efficiently run your setup, then there would be no need for or difference in purchasing two separate amps for that setup. The problem with using a 4 or 5 channel amp to drive everything is the fact that many people drive subs that need a lot of juice to run efficiently...

Most 5 channel amps are intended for balanced systems (for example 75Wx4 and 150x1). That 150W would meet the requirements of most people who want a clean, level, well balanced system with bass fill. It will not, however, impress anyone who has a craving to thump a bit. The best sub output I've really seen on reasonably priced 5 channel amps is around 300Wx1... Will that generally run 2 10"s? Sure... Will it thump hard? Meh... It would drive two 10"s alright (depending on the series), but it wouldn't really pound (well, I guess that's all in perspective). It would be better suited (IMHO) to power a single 10" or a single 12". As I said, that's the highest output I've seen from a good quality mid-priced amp.

Unless you get one hell of a 4 channel amp you will run into the same ordeal... It's difficult to find [reasonably priced] 4 channel amplifiers that put out much more than 80W x 4 (or 160Wx2) unless you sacrifice a whole lot of quality... Many lower end brands claim higher specs, but in reality they can't hold a flame to other, better quality manufacturers. The reasonably priced amps that actually can put out higher wattages are generally crap heaps...

What series of JL are your subs are you running (W0, W1, W3, etc...)? What kind of mids and highs are your running? Those factors right there would influence a few of those answers...

Tweeters generally do not use their own channels (although they can use their own channels in more complex setups, it's not necessary by any means). Generally, when running components, your amp feeds directly into a crossover which branches the power out to both the midrange and the tweeter.

The questions regarding how many watts to run your subs with depend on the series of JL sub... On their lower end you can get away with as little as 150-200W... on their high end you can't really get away with anything less than around 700W for a 10" sub (and it would run better with more)...

As far as mids and highs go; a safe range would be to power them with somewhere between 40-75W a piece.

You want a REAL amp that can handle a whole system? This is a bargain...

There's not much out there that can beat that... Especially for that price. That amp can make even me drool...
