hi i am considering running an amp to power my speakers. currently i have a Pioneer DEH- 2750 (last year model, can be found on their site in archived products) headunit. i also have a set of pioneer TS-A1681S 4 ways 6inch in the front and pioneer TS-A6971E 3 ways 6x9inch in the boot in boxes (i have a station wagon). i am thinking of amping them firstly hoping to let me turn the volume up further without causing distortion and secondly to improve sound quality. can it be done SIMPLY and economically, $300 or less (australian dollars) and will it do what im after.thanks

Find a Good 50 wrms - 60 wrms x 4channel amplifier.
Alpine, JBL, JL, Blau, Kicker, Rockford, Hifonics, Orion, PhoenixGold, Kenwood, or any other reputed manufacturer.
Keep away from Lanzar, Plye, Legacy .........etc cheaper brands.

Pioneer speakers are fairly efficient. As you amp them, be careful of the power you send to them full range. To get more clarity & protection at higher volumes, the amps built in crossover will have to be utilized. A amp with a variable crossover should fit best here. Just make sure if your not going to run a sub, the amp should have crossover settings available at the frequency needed to protect each pair. This way it will work as an subsonic filter for them. At least 40hz-65 will do fine as anything lower can do damage. Too high (80hz at the lowest setting) and some of the fullness will be lost.
If your going to add a sub later, then a higher setting can be used to produce more volume. Just stick to the brands that "Vic" stated and you should be good. Just watch out for brands that state power output that doesn't correlate to fuse ratings (10 amps per 100rms watts is a good starting indicator) .

ok thanks heaps, my other concern is that my head unit has only one set of rca plugs. i have noted that other (better) headunits have a front rear and non-fading (sub) rcas, is this a problem that i only have one? does it make wiring more difficult?

You may need a Y-splitter depending on your wiring needs.

Agreed! A good 4 channel amp with a solid 50 RMS per channel @ 4 ohms will brings thingds to life well.
That Pioneer HU, how many RCA jacks does it have and what is the RCA voltage output? (You'll find that info in the specifications part of your manual)

alrighty, it only has one set of pre outs and its 2.2volts/ 1kiloohm- does that sound right?
swez on 05/4/2006 09:52:52
Yes, that is pretty common in newer mid-budget HU's. You will not have fade (front to rear) control this way, but can use the amp gains to tone down the rear speakers.
Are you planning a sub at some point? If yes, consider the 5 channel Alpine MRV-F450. It has a 200 Wrms sub channel and only needs 1 pair of RCA's to get all channels running. (Internal control panel does all this for you) Best place to find this one is off e-bay.
They also have the MRP-F450. It's a 4 channel version.
