hi guys i am new here, i just bought these 12" Kicker L7 Solo-Baric 4 ohm. Subwoofer. Only 1 of them,NOT DUAL. heres the description becaues i am a beginner to the car audio world. lol.

Power Handling peak: 1500 watts

Power Handling RMS: 750 watts

High-temp dual 4 ohm voice coils

Titanium deposit impregnated cone woofer with rolled outer edge

Santoprene rubber surround

Full coverage back bracing

Solid pole piece

Cast-aluminum basket

Spring loaded terminals

Top Mount Depth 6-11/16"

sealed box volume: 0.88 -2.0 cu. ft.

ported box volume: 1.75 - 3.25 cu. ft.

and the amp i have in mind is the zx750.1 because someone had recomended me those amps. Help please :-) description of the amp below

* Mono subwoofer amplifier

* 375 watts RMS x 1 at 4 ohms (750 watts x 1 at 2 ohms)

* 750 watts Peak x 1 at 4 ohms (1500 watts x 1 at 2 ohms)

* Variable low-pass filter (50-200 Hz at 24 dB per octave)

* Variable bass boost (0-18 dB at 40 Hz)

* Subsonic filter (12 dB at 25 Hz)

* Wired remote bass level control

* Class D design

* CEA-2006 compliant

* Speaker-level inputs

* Preamp outputs

* Fuse rating: 40A x 2

* Requires 4-gauge power and ground leads 80 amp fuse recommended, wiring and hardware

* Not included with amplifier

* 14-11/16"W x 2-5/16"H x 9-5/8"D

To be specific the head unit I already have will be a Pioneer DEH-P6000UB. I drive a 93 Acura Legend LS Coupe. Since my rear speakers are blown. I was thinking on replacing all 4 speakers in my car, and so my next question is If I do get new aftermarket speakers, will I need another amp to power that up? If so is a low wattage amp good and how many channels? This is really my first time trying to get these sound system to setup up and I don't want anything to go wrong. If any information is needed please do ask!

If you get aftermarket speakers you SHOULD get a 4 channel amp to power them, you don't have to though. It will probably sound like if you run it off the deck too! Sundown 100.4's are great, but out of stock right now.

would I have to add up all 4 speakers RMS power handling? and get the right amp for that with 4 channels? and the same 4 ohms impedance?

each channel will put out a certain RMS power at a certain ohm load. The Sundown amp I recommended is 100 WRMS x 4 channels at 4 ohms. I believe it is 160 WRMS at 2 ohms per channel. You don't have to get a 4 channel, but it will make life easier for you.

so if i get something similar to that for my speakers. will it still be enough for my head unit to be powered to my zx750.1? with my subs?

Huh? You are going to run subs off your HU?

[kosalvick 0]

should I? i have no clue lol. i don't think so though because the zx750.1 is just enough for my subs. so I don't think i will be doing that

HAHA, I was just making sure you weren't going to do that! What do you mean in your question though?

[kosalvick 0]

ok basically. I know my subs will run with the zx750.1 lol now the problem for me is figuring out the right speakers with amp. I want to replace the 6x9 with another rear speaker that are 6x9 3way. and 6 1/2 on the doors. which most likely be 2way it doesn't matter. I don't know if the impedance on the speakers have to be all 4ohms or what lol. just confused with those

Oh its okay, we are here to help! With the ZX350.4 it is 90 WRMS per channel at 2 ohms. It will run the 6x9's well, but probibaly not the 6 1/2's.

Why wouldn't it run the 6.5's well?

It will be fine.

Ok. So which wiring kit will be able to run the speakers with the amp? A 4gauge or 8 gauge will do? And also for my kicker subs with that zx750.1 amplifier. Appreciate the help;)

[KU40 173]

at LEAST 4 gauge for power and ground. 12 gauge will work for the subs.

[kosalvick 0]

hmm. it said on the specs for that zx750.1 " Requires 4-gauge power and ground leads 80 amp fuse recommended, wiring and hardware" so would it be worse to go for a 12gauge? not sure on these. or is you recommending to use a 12gauge?

I just think it would be too much for them.

If you mean 12 gauge going to the sub then yes. If you mean 12 gauge power wire...ROFL

He's saying use 4 guage for power and ground to the amplifier, 12 guage wire from amplifier to speakers.

That's what the gain is for. You can always lower the output of the amp below what it's rated for.

But yeah, apparently I wasn't clear enough on my wire suggestions.
