Question about Ultimate Sound T3 Series 4320 Car Audio Amplifier

1 Answer

Need Wiring Help

I just bought a 2006 Ultimate T3-4075 four channel amp in another rediculous attempt to power 2 boxed Alpine S-Type 6x9s and 2 open Kenwood 6x9s (all 4 200 watts). The power and everything seems to operate properly, but I cant get any sound in the freakin speakers. I expect that once again I have been played by some retard salesperson who really doesnt know stereo equipment. The speakers are 4 ohms, but the amplifier has a 2 ohm impendency. Can anyone explain this problem to me, and possibly offer me some advice on whether or not I should take this amp back and look for another. Thanks for your help.

Need help wiring two 10" alpine type E subs to a alpine 500 watt monoblock amp

Just connect both sets of wires from the subwoofers to the same speaker output terminals on the amplifier. Make sure you keep the positive and negative wires together. This is called parallel wiring. The Type E is a 4-ohm, single voice coil subwoofer, so wiring them like this will give the amplifier a 2-ohm load, and the power produced will be divided between the two subs.

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I have 4/3/2 ch. alpine f-240 amp- i want to hook up four 6x8 3-way and one 12''sub. the amp has bass EQ on ch. 3. how would i hook it up and get the most power. can i put the 4 6x8 bridged all together...

run two 6x8s on each of the front channels of the amp. then depending on the sub you can bridge it on the rear channels.only if its a single four ohm. if its a dual 2 ohm sub run each coil on each channel. 1 coil-1channel. the other coil-the other channel. amp should run fine may run a little hot since it will be doing all it can do at a safe ohm load. just make sure it is mounted in a well vented area. should be safe.

How to hook it up to system with two 10s 400 watts per sub and two 6x9s at 200 watts each?,subs behind seats, 6x9s in doors. IF i need another amp i have one,to help push. But either way i need your help...

Hello www_mitzjohn,

I'd definitely use another amp.

The 2-channel Sony is well suited for powering the 6X9's but a monoblock would be better for the subs. The different types of speakers running from the same channel will not sound very good and likely it'll be impossible to get the impedances to match.

You'll want to set the Sony to send higher frequencies to the 6X9's, but not to the subs. You can't adjust the channels individually. So, just connect each 6X9 to one channel of the Sony and use a monoblock subwoofer amp for the subs.

Hope this helps.

Bought some 6x9's now need an amp to power them up cause my headunit is weak.. umm any advice on what amp to get.. i only need to power 2 vibe qb69 6x9s so do i need a minimum 2 channel amp? hope you can...

I know this is a very broad statement, but your budget will allow for what you buy. You will want a nice 2 channel 50 watt rms amp min. 50 watts is a lot of power for those speakers and you will be happy. I would recommend if your budget allowed a nice kenwood, Alpine, Diamond Audio or MB quart. Just make sure whatever you buy that it is a low noise A/B class amp. Nothing to special.

Take care and have fun!!

Can a rf 201s amp push 4-6x9s and 4-104s door speakers

Hello jon_jonmay,

Wiring 4 speakers to each of 2 channels, you will need to wire them series-parallel and run them at 4 ohms. If you wire all 4 parallel, the load will be 1 ohm and the amp is only stable down to 2 ohms.

According to your manual, the 201s will deliver 50 watts into each channel at 4 ohms . So it will be supplying about 12.5 watts per speaker which is about what you get with the average factory radio. They will work OK, but they're not going to be very loud.

Hope this helps.

My head unit has 1 set of preamp outputs can i conn. 4 speakers

Yes you can use a y to go to all four. Or you could bridge the four speakers wires onto the two outputs for 1 channel

Left speaker channel not working

you may have to send it in or back to the company... being that its one side it could be a blown amp or perhaps a bad speaker on that side ..

hooking up two 6x9s and a sub in bridge mode you could have a wiring problem when i bridge an amp i go from positive of one side and negitive on the other to the same positive and negitive on the sub or box

` bridge =========== > SUB
