just got a jl w7 and got some alpine type s speakers in my car.. was wondering what kinda amp would be best to power both of those?

 

Without knowing which W7 or Type S speakers there is no way of knowing what amp(s) to recommend, however, I can say you should be running two amps, one mono block sub amp for the W7 and a 2ch amp for the Type S. 94

for your w7 something in the realm of JL's 250/1 to 500/1 will power up a good amount. as for your alpine type s, something 2 channel form alpine would do your type s speaker wonders. but i know for a fact that the w7 can handle more than jl's 500/1, you might want to upgrade later on, but its gonna cost you..good luck

 

damn..theres no way to hook up subs and speakers to one amp huh?

 

Only if it's powerful and you have a few crossovers.

That leaves you with having to find a 4x250W RMS amp that is stable below 4 ohms when bridged, if you can then you will just have to turn the gain down for the two channels running the front speakers, however that brings us to the other main problem, because it takes a lot of power, [current] to make bass, the sub side of the amp will draw a lot more power then the high-pass side, and it will do it to the loss of current to the high-pass side at high volume levels, when you crank it, this will result in distortion on the high-pass.

All the above assumes you have an 8W7, if it is a 10" (750W), 12" (1000W) or a 13" (1500W) the problem becomes worse.

With that said, if you can control your urge to "crank it up" and underpowered amp will run a speaker, [sub in this case] no problem at all, just not to it's full potential, it's not the under-powering that hurts the speaker it's driving an underpowered amp into constant clipping, [by cranking it up] that hurts the speaker, the output of a clipping amp is DC current, and DC current overheats the VC, too much DC current, [clipping] will burn the VC. 94

 

thanks for the help..but got rid of the 12w7 for a 10 w6v2..planning to get a jl 500/1 for that and not sure which amp to get for the speakers..planning on bumping it occassionally, not too much. Would it be cheaper to run it through one amp rather than 2? sorry..im a noob dont know too much about this stuff

 

One amp or two, which is cheaper?
That will depend on the amp(s) used, generally one amp is cheaper then two amps, but finding an amp that will work for two, you said Type S Alpine, high-pass speakers, [probably 50W] and a 600W 10W6v2-D4 will be very hard, even more so with the 10W6v2-D4, it is a DVC 4 ohm sub, meaning it can be wired to 2 ohms or 8 ohms.
As mentioned, 4ch amps are not stable below 4 ohms when bridged. 94

 

would a jl 300/2 amp power my alpine speakers?

damn fcm thanks for all your help..o yeh..and also do subs take a while to turn on or something? when i turn on my car, the music will start playing and then like a minute later, the subs come on. sometimes the sub will just turn off and then the sound from the subs will come back on 30 seconds to a minute later. could this be a wiring problem?

 

What gauge wiring kit do you have for the amp?It sounds like it's under powered and overheating.

 

There should be no delay, [a possible 1sec. delay if a delay trigger circuit is installed] but the subs should not be cutting out.
So something is wrong, the first thing I would check are all the connections, power ground and trigger at the amp, at the ground point and batt. also check the connections to the fuse holder in the power lead, and if you are using an AGU type fuse, [big glass type] replace it, even if it looks good. 94

 

got it checked out..something was wrong with the amp..sent it in to jl to get it fixed
