his jvc kamelan hu has sub preouts and rcas plugged into them rcas and power wire ran w/ eachother to the amp, all i know its a alpine supose to be 200w 2 channel at i dont know what to one audiobauhn 12 in the trunk
i have a jvc hu dont know the model num bc im at work and car is outside i have rcas plugged into my sub preouts and ran to the amp, a pos sherwood amp 4 channels 50x4 i am using 2 channels bridged to one infinity 12 in the trunk

when we just switch amps it doesnt push my stuff nearly as hard as it will in his

 

well, the #1 thing... you CAN NOT bridge a 4channel amp to MONO!!!!!!!!!!

You are going to blow that amp up if that's how it's wired...

and that's could be causing 95% of your problem there... get a nice 2ch amp... if you're on a budget look at a JBL 600.1 or a Us Acousitcs...

I'd say it's your amps... fist thing.. you're not pushing enough juice for that sub... heck you said it yourself. it's a 200Wx2... whereas yours is wired down to a 100x1 if you only have 2 channel's bridged. there's your difference...

 

i know you can not bridge a 4 channel into mono, i said tho when i put my amp in his car wired the same say as mine, it pushes much harder then in my car and when i put his in my car it doesnt push no where near as hard

 

How are the subs wired? If/are they are DVC subs? You could have a 4 Ohm load, and his might be 2 Ohm. His speaker will be seeing twice the power from the amp.



I think

I'd almost be willing to be his sub is a DVC... and wired in parallel.. giving it 1/2 the impedence... thus 2 ohms, vs your 4 ohms...

 

HurstWS6speed..........how many subs do you have. In another post you said you have two of them and we tried for 3 days to explain to you how to wire them up paralell (I know that this is a difficult concept to grasp). Now you have 1??? WHY DID I TRY FOR THREE FRIGGIN DAYS TO TRY TO EXPLAIN THAT TO YOU.

Doesn't make a difference on the grand sceme of things if the gains are adjusted correctly.

You do bring up a good point though. Maybe they aren't adjusting the gains for the different set up's.

 

So many factors at play here.

1. You aren't dealing with the same subs so theres efficency of the subs that will come into play.

2. There's no mention of box size of these subs or box configuration. The size of the box makes a difference on a subs performance and also on how well it can perform per given power. The configuration (sealed, ported, bandpass) can also make a difference here.

3. What are the configuration of the subs voice coils? Are they dual voice coil subs or are they single voice coil subs and what is the impedance of those voice coils? Also, what type of load is given to the amp?

You give basic details of what you are comparing but in the end you aren't giving enough details to really be able to answer your question.

Since we are talking about two different interiors it could just be the way the cabin gain works out for how the subs are put in that makes that happen. The cars interior boosts the sub output a lot so that is also a major factor to have factored into this comparsion.

Just some thoughts of mine that's all.
