Dual 10" Alpine Type S subs...need power amp advice

No need for LOC or remote line with the Pioneer.

WHOOHOO!!! BestBuy has the Pioneer on sale for $184.99 guys. I just ordered one!

right so I can just tap into 2 speaker lines and then crimp those to the provided wires to rca and plug into the pioneer right?

If you have or have access to a decent multimeter I'd double check the wiring to make sure it's 2 ohms. Simple enough test. Just hook the meter to the pos and neg of the set up before you hook it to the amp and the multimeter on ohms resistance and you'll know what you have. That way you know and you don't either get less power to them than you expected or blow an amp because it's too low a resistancefor the amp.

good idea. I'm not too worried about blowing the amp since the Pioneer I ordered is 1 ohm stable. I'll make sure it's wired correctly though. Thanks!

Make sure you set your gains correctly. If anything, you'll probably want to set the gain on the side of caution versus aggressively. Those Type S subs are pretty efficient and don't take much power to make noise....even in a sealed application. Best of luck

Ya I realize the Pioneer at 1200 watts @ 1ohm is over powered for these, but I'd rather have more power than less...power in reserve and the option of changing to different less efficient subs later if I decided to. I should have the amp in a couple days!!! Crutchfield price matched Best Buy so I ordered from them.

does anyone know....where the speaker wires are in the back of the truck if you do not currently have a sub installed? I need to be able to tap into the speaker wires to get input for the sub. are they in the center? under the seat? how do they reach the rear doors? TIA

 

[JinxCanada]

maybe I should just wire this at 4ohms instead of 1ohm? 500 watts rms might be more than enough for the Type S subs rather than throwing 1200 watts at them? would this be a better/safer option to go with?

 

[BWL]

May not be an option depending on voice coils. Can only run double the speaker or half. Meaning if they're both 4 ohm and you run parallel you get 2 ohm and in series you get 8ohm.

 

[adrianp89]

Always run lowest ohm so you have overhead power.

If you have dual coil coil subs and they're both wires for 2 ohms I'd stick to the 1ohm set up. Just crank the volume till your mid to high level speakers start to distort on something with heavy bass and set you subwoofer gain up until it starts to distort and then turn it back till it doesn't. What are the power ratings for the subs RMS and is the pioneer 1200 peak or RMS? I only ask because whenever I've ran more power than my subs could handle it sounded good and I couldn't resist turning it up until I melted the voice coils. Never took me long.

I believe they are 500 watt rms subs, but i'll have to take one out to confirm. the amp is 1200 watts rms at 1ohm and peaks at 2400 watts.

I looked it up on alpines site. The type S 10" is 500rms 1500 peak capacity. Should be ok, but i'd turn the gain down a touch more than usual to be safe. I'm guessing they're dual 4ohm voice coils wired to 2ohms each.

 

[JinxCanada]

this is the EXACT subs that I have in the box.

[JinxCanada]

so it looks like the older model Type S is only 300 watts RMS. hopefully I don't blow them up....lol

 

[adrianp89]

Back in the day there was a guy running 2500 watts to his 10" Type-R.

It was all about how you treat it. Don't clip it and it will take more than rated, box size is also a consideration. The smaller the box, the more power it can handle. Also how you play it, heat kills speakers, so if you are jamming on it non stop, it will take a toll.

Always run lowest ohm so you have overhead power.

I agree with a few exceptions...I do not like relying on 1ohm power...if an amp is "underpowered"in 4ohm applications, but I can get that extra power in 1ohm...I will go with a higher powered amp @ 4ohms versus relying on 1ohm power. Some amps are 1ohm stable but it adds extra stress and heat to the amp which is never good. I like keeping all equipment comfortable. Amps get hot and I get that...but it may be my conservative nature. I am all about overhead power. Im running 365 watts to my 100 watt rated midbass...but its at 40hms, there's zero distortion, and my midbass speakers are always happy and never uncomfortable. Sub frequencies are very dynamic, can hit very hard with gobs of power outta no where...I personally would try to keep the amp load @ 4ohms for those type S subs....300-500 watts will make those subs pound (i have owned type S 12's in the past....gave them 300 watts each with great success)
Also, let's face it....the Pioneer amp the OP bought is not the highest end of amplifier out there....it offers great power for a great price...but that amp will be more comfortable pushing from a 4ohm load.....which may sound better than a stressed, overheated 1ohm with cut gains. Just my opinion of course

how would I wire both subs at 4ohms though? I know the amp has 2 speaker connections....should I try connecting to each output to each sub? would that keep me at 4ohms?

 

[BWL]

Do you have 2 sets of connectors on the sub box. 1 for each sub, which are already 2 ohms each. If so you wire the positive to the positive on one and the neg to the neg on the other and then run a jumper wire betwen the un used positive and negative. This will wire them in series and give you 4 ohms. Still check with a meter before connecting to the amp as it's good practice.
