ive bought a pair of type r 4ohm coaxials and im trying to figure everything out before i install them.

i was wondering if they can handle 140rms? because my amp is a crossfire vr354 and is rated as

35x4@4ohm
70x4@2ohm
140x2@4ohm*bridged

would i be able to wire the speakers up to run at 2ohms or is bridging them my only choice to make power

I was recommeded not to throw my sax125.2 at a some alpine type r components

how well do your speakers take the 125w's?

ttt

please someone chip in some information :D

would 140wrms be way too much for type r coaxials??

Alot they are very inefficient, I had them on like 200w but i also know what im doing.

i think you would be fine. bridge the amp. 1 coax per side. just use the high pass x-over setting, preferably 80 to 100Hz.

Mine sound like ballz.. running them and mb comps on a T400-4. high pass for the type r's around 90-100 hz, gain 5 out of 11 in the rear doors of a tahoe????

mm dam..so you wouldnt recommend them being powered that high?

About 200 watts a piece, but that means nothing. It just means they're inefficient. I ran 4 off them and IMO I've heard other brands get louder with less power like Focal and Boston.

I had 4 type r coaxials and I only ever ran them at 95 RMS on my amp, but I also didn't set the high pass and two of them eventually blew like within a year. My music is country and not a ton of bass, and one blew I believe because that channel picked up interference the other one I have no idea about.

say if i were to NOT use the hpf how quick would these speakers blow?

i like midbass and im not going to be able to order my subs,etc till about 2 weeks

Mine blew in under one year on 95 RMS with country music so if you put 140 to them and listen to any sort of bassy music, fast.

Where is your sense of adventure? I am running two Lunar L60x2 amps with one bridged to each set of door components in my Civic! My door speakers contain an Alpine Type R 6.5" woofer and a CDT TW-25 tweeter. I think the Satnet crossover will blow capacitors before I hurt the speakers. I just hope they don't take an amp with them if that does indeed happen.

Anywho, with the gains as far down as they will go, I get 140 watts RMS @ volume level 25 on my Alpine HU. Those little Lunars are capable of outputting 280 watts RMS each:eek: I finally found a "newer" amp that gives me great RMS power and headroom in a decent footprint:veryhapp: I guess I will start putting my Linear Power amplifiers up on eBay now:eek:

Not meaning to highjack but I just had a simple question....So with my Pioneer Revs it would be ok to give them around 100 watts RMS as long as I keep the HPF on and cut out all the lows right???

And set your gains properly!;)

In most cases it is too little power that damages speakers from clipping and distortion produced by over driving the amp. Granted, it is quite possible to destroy speakers by giving them too much power too if you don't pay attention to the signs of distress. Regardless, I would rather run too much power than not enough!
